Bitmain is proud to announce that the AntMiner APW3-12-1600 PSU Series is now on sale!

The APW3-12-1600 Series AC-DC PSU is specifically designed with mining operations in mind, and combines high conversion efficiency and a strong dynamic performance into a power dense package. It also features short circuit, overload, overheat, low voltage and overload protections.

1. This PSU includes  several features which make it optimal for cryptocurrency mining operations, including:

1) The air flow direction runs from the AC input to the DC output, which is the same configuration as most miners. This proves beneficial for those with large-scale mining operations where heat management is a major consideration.
2) The PCB uses a conformal coating to prevent damage from high voltage spark discharges on MOS pins, or near high-pressure solder joints when external conductive particles or dust enter the PSU.
3) The APW3-12-1600 can work stably in environments with a 50°C ambient temperature. If temperatures exceed 50°C, the PSU should be underclocked (refer to Max Load vs. Ambient Temperature Graph in the user guide for details). Considering the high temperature in mining operations, all internal components are selected with a standard of 105°C, so the APW3-12-1600 has a much longer lifespan than a general use PSU under similar high temperatures.
4) The APW3-12-1600-B2 uses a PCI-E connector which is compatible with currently available ATX PSUs, as well as most bitcoin mining machines.One APW3-12-1600 is enough to power two AntMiner S5s at the same time.

The high power efficiency translates to big cost savings -- if one uses a secondhand general use PSU running at 83% efficiency, when compared to the APW3-12-1600 running at 93.8% efficiency, assuming an electricity cost of $0.10 per kWh, a user could save more than $150 USD per year in power fees.

Very nice and official PSU :)

I don't understand why other PSU manifacturer never offered a mining PSU.

Good job, Bitmain! Is it an allusion to your new not yet announced 1U miner?  ;)

No, its the same PSU in the S4+, which is 3U.

PCI-E cables 16AWG or 18AWG?
Noise? and at what fan speed?
Fan speed variable or fixed?
Who is the original manufacturer?

Good question, I'll try and find out. The spade connector version used 10AWG.


I couldn't notice the fan noise even during a 45C ambient test, unsure on the RPM but its not quick.


This unit can 100% load @ 50C and 80% load at 60C so I would have thought it was variable to hit those higher numbers.


I doubt they'll say who the OEM is.


It was always the plan to sell the PSUs.

https://bitcointalk.org/index.php?topic=1035657.80

sorry bitmain but at that price used server class delta psus is better option

and please show me a delta server with a breakout board for 12 pcie connectors they said 12 pairs in the copy but I think they mean 12 connectors


.that does 1600 watts at 92% efficency

with a 1 year warranty  .

cost 155 usd.

My issues are not with price .

Quality control based on the post above yours .

and does it do 92% at 1500-1600 watts?

does it do 93.8% at 1200 watts?

last question is are the wires 16 gauge? 

I could see someone running 2 s-5's and this psu have issues if the wires are 18 gauge.

Its 18AWG.

not good but thanks for an honest answer.

if I buy this with 2 s-5's  I will be pushing the wires at freq 375 and higher.

btw 1 of these psu's and 2 s-5s is 911 usd with shipping

1 s4+ is 1071 usd with shipping

In that case it would seem appropriate to provide a maximum amperage per connection in the specs and make it clear, it could be dangerous for your customers if not..

18AWG? Gross. Though 1600W at 12 cables is only about 4A per wire... That'd be good enough for most things. I'd like to see one of these hooked up to some Neptune cubes and watch the entire setup burst into flames though.

Also, Phil, how does my DPS-2000BB breakout board and PSU stack up to your criteria? The efficiency might not be quite as good, but the board holds 12 cables natively (I've run 16 without issue, pushing two Prismas per PSU) and a kit costs less than $155. We don't 1-year the PSU (90 days typical for used equipment) but lifetime on the board and cables.

By the numbers this is a nice-lookin' PSU. I hope Dogie's right about the fan not sounding terrible, because every 1U fan I've listened to (for example DPS800, DPS1200 and all SP rackables) are super annoying. It'd be nice to have user-defined cabling too.

actually you don't need breakout boards for them i solder wires directly to psu pins it only requres time and 100W soldering iron

Holy shit.. Be careful with these things guys..

Look at those pictures above.. Looks like bitmain is selling house burners if you ask me.
I'd advise everyone to be careful as hell if you are buying these and make sure you inspect them inside and out.

I'm disgusted that shit like that even made it through their QA testing... Step up your game bitmain before you kill someone.

So, does this mean that you will only provide support for people using Bitmain^(Tm) power supplies for future miners?
Or is this just me being paranoid?

Why would it be? S6 @ 375 is no more than 600W pre PSU = 150W per cable strand = perfectly fine on 18AWG. On tubes we were doing 250-300W per cable strand on 18AWG which was the sensible limit.


Fixed :D


That's what I expected to, thought I'd have to stress test it during the first day then turn it off but nope, I actually can't hear the fan in my setup. While I can't tachometer it (blades are too small for a marker dot), it does look pretty low RPM. Maybe we can have different cabled versions in the future.

Extremely paranoid :P As long as you're not using a 300x 12V rail PSU made by SUPERHIBIGPOWERWOWLED corporation, I'll help out where I can.

It has short circuit protection, as it worked in this case. I'm not sure what the point of that drilled hole was, but it will get fixed.

No, I stand by what I said. It'd be fun to see someone hook one of these up to a Neptune thinking "oh, 1600W is plenty" and see the jackets on the 18AWG wires wilt off within a few seconds before the whole thing starts burning. The PSU itself might survive but not the cabling. It's a terrible idea (I can't in good conscience ever recommend anyone run Neptunes) but if someone does it I'd like to see video.

Be much less fun if it had 16AWG wires. 150W on 18AWG is probaby okay. 8-pin PCIe for GPUs are probably mostly 18AWG and those are rated for 150W by the standard, which means they're probably capable of more, and 8-pin PCIe only has three power leads.

These power supplies are great but it highlights the need for bitmain, and other miner manufacturers, to continue to produce miners without power supplies. I'm sure we are getting a bottom price or close to from Bitmain. But we can still do so much better with recycled server equipment. Here are some numbers:

Bitmain PWS: 1600w $155 or .096875usd per watt

2880w IBM Server PWS:
$40 for power supply
$60 for breakout board
---
$100 or .034722usd per watt, and, you get better efficiency, these are actually rated titanium 80plus level so >96% eff at 50% load. Better fans, 3 of them for redundancy when one burns out. You also get to choose the gauge of wire for your pcie and it is not hardwired but modular. You also get to support the smaller bitcoin guy with the breakout boards.

I'm sure bitmain is not charging us 3x their actual cost. And I'm sure IBM paid a lot more than $40 to manufacture those 2880w power supplies.

But remember that there are two 8 pin PCI-Es per cable rail = 'rated for 300W' on 18AWG. We're running a single PCI-E per cable rail on this PSU.

Regardless of short circuit protection or not that's pretty shit workmanship not to mention quality control if they are letting garbage like that past.
I've owned Bitmain devices in the past (I think you help me set them up actually Dogie) and found them to be of decent quality..
Seemingly not the case with these power supplies though.. :/

Depends on implementation. All I can speak for is 150W per 8-pin, and the PCIe standard doesn't actually have provision for 2x 8-pin per card last I checked. I would not run 300W through 18AWG wire. I would run 300W through 16AWG wire, but I would never run more than 300W through a single PCIe 6-pin no matter what wire is behind it. But 150W through 18AWG is no problem at all.

It is noisy psu??????.,

Some where I said   2 s-5's at freq 375 would push at these 18 gauge wires.


the s-5 at freq 375 uses 1200 x  .52 = 624 watts  that is 162 watts per cable on the ac side  or 150.88 watts on the dc side

I will amend my statement


two  s-5's at freq 400 would push the 18 gauge wires beyond spec


1300 x .52  = 676 watts x .92 efficient =  169 watts per cable  or 155.48 watts on the dc side.

I have mined 24/7/365 for 3 years.

This psu should have 16 gauge cables.

That said  12 cables 1 power cord 1 year warranty at  155 shipped is not terrible.

Personally there are 4 sellers on bitcointalk

sidehack has server psu's

quakefiend has server psu's

the 2280watt one  is plat jabborwocky? sells it.


pmorici has a very good 1200 watt intel plat that I reviewed  this was 136 shipped for 1 with 4 16 gauge cables. 


I am not sure I need one from bitmaintech with only 18 gauge wires

Shipping Cost  0 BTC
 ( 0 USD )

Freight calculation error, please send e-mail to info@bitmaintech.com

Can you PM me what you had in basket and going where please?

While it's quite possible that all the Bitmain gear has enough PCIe connectors to never draw more than 150W through a 6-pin connector, that's not universal. My experience is that the power supply is usually a better long term investment than the actual ASIC mining hardware. It seems short-sighted to use 18AWG wire instead of 16AWG wire. Of course maybe this will just be an opportunity for somebody else to produce a "kit" that upgrades the Bitmain power supply to replace the 18AWG wires.

Bitmain should reconsider this choice, or offer a "heavy duty" version with 16AWG for a $5 more (IMHO).

yeah they should  as this psu driving a pair of sp-20s'  can do 750 dc per sp20 which will melt the wires

I have seen a lot of psu stories about melted wires.

worse 1 sp20 maxed to 1600gh will use 1240 watts dc  which would surely melt 18 gauge wires.  so much easier to use 16 guage.


or as alh says a lite duty 18 gauge maybe 12 pcie connects


and a heavy duty 16 gauge maybe 8 pcie connects.

I run S3s with only two connectors all the time and they pull 360w or so, so that's 180w per cable right there.  There's a ton of people that do the same thing as me...

The cables that I'm selling with my kits are 16 gauge for this reason and because of what sidehack posted above.

I'll be the first to admit that I have a bit of a conflict of interest seeing as I'm selling mining PSUs myself, but between the pennies scrimped to save on 18 vs 16 gauge cabling, and the QC woes posted just earlier, I have to wonder just how well made these kits are compared to what I or other members here such as sidehack and j4abberwock are selling...

well I saw the photos of metal shavings in the psu. I left that alone only because the 15 s-1's and 20 s-3's I got  had 1 bad cap.  most likely it was knocked off when it was packed the s-1's had very tight  static bags which I think knocked off a few caps.

Either when packing the s-1's or pulling the s-1's out.

So for quality control on s-1's or s-3's 34/35 worked out of the box.   and of the working 34 every worked and when I sold them every buyer said they got working gear.


But back to 18 gauge wire.  I ran 23 gpus in 10 pc's from sept 2012 to june 2013.  all in my garage pulled 5kwatts or more pretty steady.  long term running 24/7/365 is hard on gear.  wires get soft. shit burns fans fail etc.

my garage is 22 by 24 about 500 square foot concrete slab 5 inches thick.  the entire slab got warm around 40 day into non stop mining  say oct 30 2012.  stayed warm the whole winter and when I sold off all the gear and switched to ASIC MINER usb sticks in June of 2013 the slab still felt warm for about a month.

Point is 18  gauge wire is "stupid cheap" or the polite way "penny wise pound foolish"

I would love to see some first adapters give a good long review on these .  attach it to the sp20 and see at what point the wires melt my guess is 1400gh would take a while to be an issue  but 1500gh to 1600gh and problems will happen.

I have a bunch of SP20s here, if someone wants to send me one I'll take a video and see how long it takes to melt it at top speed haha

I guess that for wholesale buyers the price is more or less acceptable.  >:(

Well dogie got back quick to let us know it was 18 gauge.  Maybe if we complain more they will go to 16 gauge.

Another Joke from bitmain !

The hell with the PSU and bring out new miners made with newer chips already !

Like the long awaited S6 or S7 !!!

I am tired of BITMAIN !

you somehow went from saying its 18awg to justifying the safety of 16awg wires.

If this is made with 18awg, thats not good. It might be fine for an S5, where you occupy all 4 connectors with thier own 18awg wire (and could fit 3xS5 on the 1600W PSU, possibly with a tiny amount of underclocking if required), but for a lot of other hardware (ie: anything that would draw >180w/cable) its dangerous.

my rule of thimb is that 18awg can handle a maximum of 150-200W depending on the cable quality. 16awg can handle 250-320W depending on the cable quality. I would much rather see bitmain offer this PSU (or as a secondary option) with 16awg wire for a few dollars more.

How about no dollars they can keep that junk. They would have to pay me to take it.

i was playing with a whole bunch of dps800 power supplies last year.  two of the pins can tell the supply fan to run at low speed.  and the dps800 gets very quiet.  using each to power 2 antminer s3's, never had a problem with failure or overheating due to the low fan speed hack.

Fixed, I was talking about 18AWG but wrote 16. As I said before, anyone powering tubes with 18AWG would be doing 300W+ from their cable rails. Look at the Corsair CX750M for example, its 750W rated for 12V yet uses 2x18AWG cable rails for that. Do you think they'd sell something potentially dangerous with 375W per 18AWG cable rail? I've 100%+ed that PSU and while its toasty its certainly within limits.

That Corsair CX750M is a real hunk o junk. I have 4 dead ones here from over the past year. One wouldn't even push 500watts out of box without shutting down, two popped with shotgun bang and accompanied flames, only the last one died quietly, probably because I wasn't there to hear the screams. They were by far the cheapest most sloppily made pws I ever had in my mining setup. I would laugh at the thought of even including them in my mining toolbox at this time.

I've been running 3 of them @ 100% for nearly 2 years, no problems here.

This is very good job done BITMAIN!!! It is high power mining PSU with competitive price compared to other 1.6kW PSUs. I do not uderstand stupid comments comparing NEW APW3 with used DPS1200 or other. If someone wish to compare, please compare NEW with NEW, not NEW with USED!

Again, very good job! Please consider to add more qualified suff to QC, your products are not perfect and like to fail soon.

I run TWO EVGA 1300 watt G2 supernova's at roughly 50% load and they run at ambient temperature "ROOM TEMP" not even the slightest bit warm !


one S5 on each PSU.


 ;D ;D ;D ;D ;D ;D    

I don't know if I would brag about this.   That is pretty much overkill.  And at around 80 percent is most efficient.

*I stand corrected 50 percent is a little bit better.  I can still learn I guess :).  

But I still would go for at least 80 percent gold.  And would run closer to watt's used and not 1/2.  Just would take a lot for that extra few percent to pay off a EVGA 1300.

rule of thumb if your going to run PSU's 24/7 run them at around 50% load max. this has been proven in a lab.

If you run them at max load you will get ripple voltage which is an UNCLEAN VOLTAGE with BITMAIN antminers knowing how sensitive they are. Ripple voltage is unclean period don't run them more than 80 percent load if you must. this also has been proven for many years in a lab.

Single rail PSU is the way to go. I get hardly any HW errors and I don't have to reset them every week. and that's enough proof for me.

 

That actually looks pretty good to me and I'm a huge fan of the HP 1200w and the IBM 2kw PSU's. It's fun to putter around but...

Modding and soldering cables on the HP's for running 3 s3's or using the breakouts and cables from http://gekkoscience.com/products/IBM2K_board.html (http://gekkoscience.com/products/IBM2K_board.html) for a IBM 2kw PSU takes a fair bit of time each. The 2kw PSU, breakout and 12 cables total $133 vs $155 for Bitmains - pretty close there already, scale power/price and pretty much dead even.

 it takes me about 1hr total to twist the 12 PCIe 36" long 16ga cables into nice looking ones followed by twisting them into 6-pairs of cables to look pretty. Then screwing down all the wire lugs  onto the terminal block. Once that's done more twisting. This time the 6-pairs into 3 master cables running to the miners. Plus the IBM's do not have fans so gotta do that as well. But, sure looks nice ;)

Most of my main Ant colony http://imgur.com/gallery/gvJDH/new (http://imgur.com/gallery/gvJDH/new)

With Bitmain's we get the 8 PCIe needed to very comfortably run 2 s5's even OC'd with 4 spare cables for whatever or can run 3 fully plugged S3's. Also uses the normal C13/14 plug so easy to find cords. A minus is the cables only being 18" long - makes for interesting arrangements..
Query: Does it have local/remote control, status pinouts or can it be tied into n+1 redundant?

With the IBM 2kw and 12 cables (again, 36" and 16ga) I comfortably run 3 S5's pulling 1.8kw, no spare PCIe. It also uses the harder to find C19/20 plug. But the breakout provides local/remote control - has a switch for local, has headers for plugging in up to 2 of the needed fans and has local/remote fan speed control as well. Also has scaled current output signal (33mv/Amp) and can be wired as N+1.

That said, Bitmain's still looks good enough for me to give 2 a try. No time spent futzing around, just plug in and mine ;)

The stock boards don't have the current measurement anymore; that feature was too expensive to implement in mass (not many people wanted it). Also, the Bitmain PSU is C13/C14 plug and the DPS2K is C19/C20.

Post corrected about the plug, thanks. Might as well add that one source for 240v C19/20 cords is http://www.stayonline.com/detail.aspx?id=38741 (http://www.stayonline.com/detail.aspx?id=38741)

Bummer about the current signal. It isn't derived inside the PSU and just bought out via the high-density plug?

are there no shipping charges on this?

looks that way.  it is small and lite compared to a miner.

Sorry to disappoint but the bug has now been fixed :P Shipping charges for all!

you just love to say that doggie it must be most gratifying for you especially when you get yours free !

  and it is now 155 + 33 = 188   usa

 which really is too high   but if some one gets it and wants to show it on power ratings please do. I am curious to see if it does 92.0% to 93.8%

With Bitmains previous record with PSU's, I would be very wary of purchasing these potential fire hazards. However, having seen the terrible workmanship in the pics uploaded on the first page, I would now say avoid these PSU's at all costs. Stick to superior quality, proven & cheaper server PSU's off ebay.

These things could, quite literally, kill you. They should be banned worldwide.

Bitmain, what are you playing at  ???

PatMan dude, bang on! Let's just look at those pics again:


These things just scream one thing: DANGER!! I can't stress enough how much miners should avoid purchasing these if they value their homes, possesions & lives.

Absolutely Shocking.

GREAT BITMAIN IS NOW IN THE BUISNESS OF KILLING PEOPLE. way to go bitmain I would never buy one after looking at those pics.

If you paid VAT to dogie for items you should read this thread:  https://bitcointalk.org/index.php?topic=1018906.0

not my link just pointing something out.

Dogie I always knew you were a scammer one that works for bitmain to.

Dogie you sure you didn't build that supply for bitmain.
  

Guys not to defend anyone.  Bitmaintech built pretty good

 s-1's
 s-3's
 s-5's

 they don't burn up often.

And while the psu in the photos looks bad on the inside no one  else has done any photos of it unboxed then opened.

Frankly I am not interested in buying one to test it for everyone   because


it is 188 usd to my house
I do not need it.
I know I do not want 18 gauge cables.------------biggest reason is this.


I AM CURIOUS does it do 92-93.8%.
I could hook a lot of lower power gear to it.


But I am only saying  188 shipped to the USA is high price.

I rather 16 gauge cables .

Agreed, 18 gauge isn't enough & the price is too high. These reasons alone are enough not to buy one, but the workmanship, quality & history of Bitmain brand PSU's (S4) are even more reason to avoid these. Bitmain have already lost one of their own mining farms to fire, it's no surprise why looking at those pictures, you'd think they had learned their lesson.....

As far as PSU's go, you can't risk compromise: quality parts & workmanship win every time, something these don't have. It's just not worth the risk.

Did you just make that up?

Pretty sure he's thinking about the mine in Thailand with a bunch of Spondoolies(not owned by them, but built out with their equipment) gear.

Dangerous stuff indeed. What is even more worrying is the question of quality control - what happened in that department? If this sort of thing can get through QC, one has to ask, what else does? QC is of utmost importance, especislly when high voltage/amperage power units are concerned, & is supposed to stop this kind of shoddy workmanship ever getting out into the wild - but here it is......

I'll pass on these things thanks, & would advise everyone else to do the same until Bitmain pull their finger out.

Giving advice about electrical safety when you are not qualified / certified to do so is a crime in the UK (and many other jurisdictions). Latif aka dogie, your only qualification is taking pretty pictures of mining rigs & waffling on about them plus forging education credentials and that does not qualify you give advice about electrical safety. If at all bitmain want to flog these wares, they should get them certified by BSI (or the relevant authorities in respective jusrisdictions) which will itself speak volumes, rather than let users rely on a non electrically qualified fraudster's advice.

I provided the feature from the specifications, but feel free to report me to the police then let us know the crime reference number if you believe a crime has been committed. BSI is not a certification agency, they're a national standards institute - two very different things.

I agree with you 100 percent doggie is a fraudster and will be locked up soon for that and other things !

This is a bitmain issue and your clearly dangerous advice to users is tantamount to criminality. And that you're clearly refusing to take heed of even other users who are, on the face of it, qualified electrical engineers, I'll notify the HSE (who may decide to take it up with the police) of your fraudulent and illegal electrical advice.

Obiter dicta: What part of this did you not understand, you fraudster?

And I can't believe people haven't yet gotten tired of flaming Dogie in every thread on the forum. Does anyone want to fetch one of these PSUs and formulate an opinion based on actual performance and inspection, or do we want to just keep trash talking anything and everything based on a few scattered bits of information and massive doses of prejudice coupled with the comfort of relative anonymity?

Seriously, guys. The only way you can say something that hasn't already been said a hundred times is to actually discuss the product for which this thread exists.

Get rid of Dogie and we will. I am not going to buy that PSU Just to test it and Give a review I will never use it anyway even though I am qualified to fix the issues.

If someone sent me one for free like Dogie gets then I will. Other than that theres no point in doing that.

I am sure the pun was intended in "getting tired of flaming dogie" as this PSU will most likely burn down somone's house if I am to go by dog1965's advice, seeing he is a qualified electrical engineer.
But if you tire of reading about pointing out the clearly inept "advice" spouted by the fraudster, there are as many people that tire of your patronising, wiseacre, holier than though posts too. But like dog1965 said, I too shall NOT be getting one of these just to prove it won't burn my house for that price. If you want, you get one! And don't tell everyone what to post in this forum.

I'm actually considering buying one, just to see what it'll do and actually know things for real. I like knowledge. I don't like assumption. I've never though of myself as holier than anyone else here, just more vocally annoyed about people who are very vocally annoyed about the same thing over and over without actually doing anything about it except increase the general "useless noise" level in almost literally every thread ever. Do I agree with everything Dogie says? Nope. But do I agree with taking everything Dogie (or anyone else) says to the extreme and threatening legal action over every available comment, and commenting the same opinion I've already expressed repeatedly based on no experience with the thing being discussed, as a thinly-veiled means of staying "on topic" while giving myself another opportunity to be a dick to someone I've never met? Additionally, nope.

I'll just leave this thread alone until someone puts up a review about the actual product. Might be me. Who knows. Y'all have fun with it.

There's your presumptuous, holier than though nonsense manifesting itself in just one sentence!
For the record, you are not my point of reference on that, and you were NOT the first (let alone only) person to mention the inherent lack of safety of this particular PSU.


Yep, good riddance ... hopefully you keep away for long, you patronising twat.

Looks like we got some fanboys here  ;D why should bitmain produce better psus than others?

Stop throwing wood on the fire. That is known as being a fire starter.

1) According to pics the thing could be unsafe I would sure inspect it and fix it before I tuned it on I have the whole lab. Just trying to make a point.

2) Like I said if someone wants to send me one for free I will do it. But I am not going to pay for some forum's satisfaction when I can dam well make my own.

3) And I will not post my credentials as an engineer because its nobody's business.

4) In the labs we work together to analyze a products safety or to fix the design flaw and get the bugs out that other people made using proven theory's. we even create dangerous conditions just to see what will happen. A lot passed,  a lot went up in flames or exploded then went in flames.


5) I also like fact which is proven by sound methods and formula's.


6) we don't need bootleg doggie out here "WANNA BE ENGINEER"  it is only making things worse.

Those of you who are engineer's you know exactly what I mean.






  

This thread is so far off track....

Anyone remember this?  https://bitcointalk.org/index.php?topic=139380.0

Just plug into wall outlet.

Are you deleting and reposting your pic now?  Earlier your comment was below my last one...

No just added something to it in case you have not noticed in wich you should have.

Guess I missed whatever super clever detail you added to the pic that you seem to expect me to have committed to memory.

You said that not me all I meant was you should have looked but not a problem good day.

Man, some of you guys are fucking annoying. Get off of Dogie's case, or start a thread dedicated to Dogie bashing so you folks can congregate there and circle jerk each other in privacy so we don't have to continually read your fucking useless drivel.

Since none of you geniuses actually have one of these, I'll comment on them. I've got 3 S4+, and so far they're running great. Not a single issue. They seem much better than what came with S4s, by a long shot. Will they die in 2 months? Who the fuck knows. If BITMAIN is serious about these PSUs, they should send a sample to Oklahoma Wolf over at jonnyguru.com. He'll reveal the truth about this PSU in short order. (BITMAIN: If you're interested in this, I can set it up... Just PM me)

About those 2 pictures posted earlier... The first has nothing to even do with the PSU, it's a heat sink fin loose in the main S4 case. BITMAIN QC failure for sure, things like that are hardware killers. The second picture is of a pinched 12V fan wire inside the PSU. Yep, another QC issue, but one that falls on the PSU OEM, not BITMAIN. BITMAIN can't be expected to open up every PSU to check them out for physical damage, in fact they'd probably cause more problems than they'd catch if they did. What that picture tells me, is that the short circuit protection works perfectly in that PSU, and it saved the PSU from failure. You'd be a fool to think this only happens to BITMAIN hardware. Pinched wires have happened with Delta PSUs, Flextronic PSUs, Seasonic PSUs, etc... Shit happens. It'll just happen much less with the big boys I just mentioned.

Now, this PSU is a no-go for me. 18AWG wires and unknown quality means I'll stick to used server hardware made by the likes of Delta.

Blah Blah Blah Blah.....

All of his comment was very valid.  Like a product or not your able to voice your opinion. 

Eventually it becomes trolling like behavior.  Posting meme equivalent images, trying to hurt a product over and over.  It becomes bad behavior. 

Exactly like a product or not you have the right to voice in this case post and image or opinion as many times as you like to as well. when I said blah blah blah  I meant its getting repetitive nothing else. and of coarse his comments make a lot of sense "Except the cursing" especially Johnny guru he gives excellent reviews of PSU units.

to sum it up this forum reminds me of the jerry springer show that use to air in the USA years ago I don't know if it still does.


 

Pot, meet kettle.

So after all the complaints mine included.  No one purchased this to test it?

 At bitmaintech :

 I have no need for it  so I will not buy one ,  but If you send me one I will test and review it and mail back to your   USA

location.  

I will run 3 s-3's  using a 240 volt source.  I will use the 12x  18 gauge cables   4 per s-3 and determine the amps is uses.

I have no interest and gave a fair review of your s-5 I also showed how to mod the s-5 to decent noise levels.

3 s-3's pull about 1200 watts at freq 250    your gear should do a good job running 3  s-3's

I would do a comparison  to an evga 1300 running s-3's you should get better watts.


Note I no longer do any signatures and have been known to do fair and accurate  reviews.

I can test it with one S5 and send in to your representative in Russia too.  ;D Everyone have seen my freestyle review of S5.

It was a good review.  With the s-5 you can push the individual pcie cables harder then I can with my s-3's

An s-5 at 1300 gh would be a good test of the cables.

Being realistic, what can we actually test on a PSU without proper DC equipment? "Yes it turns on, yes it didn't explode, yes it powered some miners, yes it consumed this much power". We already know these things from the 100s and 100s of S4s its in. The circlejerk of made up stuff is what needs to change, and it probably will now the guy with 7 different accounts is banned.

Basically. All we (most of us I'd imagine) can do is measure AC in and DC out and come to a very rough efficiency conclusion. Most of us won't be equipped to measure anything else.

Dogie, can you ask someone at BITMAIN if they'll stand behind their product by sending a review unit to jonnyguru? I'll gladly put them in touch with Oklahoma Wolf, or even take care of making it happen myself if their English isn't up to snuff.

I could pull out my fluke and tell some about it.  I have not had a reason to use it in a while.    Normally I use my cheaper gear for just getting readings.

I have had 3 S4's all new from Bitmain.  All still work great on PSU not a single issue.   So I personally have not had a issue with Bitmain PSU's.   

Asking, I guess it depends if they want to sell 100 or 10,000 of them.

Did you get that fluke for free to ?

This thing is, on the face of it, a fire hazard!
Once we get an independent, forum trusted reviewer that can give an unbiased opinion (not pretty pictures accompanied by waffle from a certified VAT fraudster) then that opinion can be changed. Is this PSU certified by any EU agency anyway?

No... i payed quite a bit on it at one time, plus accessories. Looking back I should have spent it on something else.... but I always wanted a fluke.  

I have not gotten one these for review either..... so might check your sources.  

No. Only http://snappi.wpengine.netdna-cdn.com/wp-content/uploads/2014/05/FCC101.png and China Export

and yet to see any testing on this by anyone on any gear.

which shows the current state of home mining is pretty much dead at the moment.

Or the current state of people able to test this thing effectively don't care to put up the $180 for it.

I offerred to test it and return it to the USA rep.  They never responded. Other then the dog barking at my generous offer of 2 or 3 days of testing it at no charge to them. and returning it on my dime to I believe Colorado.

So no one has offered to prove if it is a platinum psu. or if it is not.

I also wouldn't mind playing around with one, but I don't have the money to spend on stuff I don't need. I wonder how many they'd sell if it had your stamp of approval? Or conversely, how many they specifically wouldn't sell if it had your stamp of rejection? Maybe they're not willing to make that bet. Or maybe they figure they're selling enough of them anyway that it's not worth coordinationg a handoff.

Always hard to tell.  Some gear I said was great sold well.

Many times newer people will trust me due to my 11 year ebay record.

I also post on:

I have a decent rep on the net since 1998 which sometimes is longer then the person reading the posts.



    My gut feeling is we are going to see a big shift in mining.   Big farms 10ph or more are looking at  a huge hit if price does not come up.
I really think putting a chip or two in gear that always runs will take off.
It would avoid the hafling problem coming up.
I have 3 cable boxes and a cable modem they are 24/7/365. Some small chips may be the way to go.

It could be a lot of fun for you in a few years.  Getting  scrapped routers with super good chips and building .05 watt per gh miners.

I don't like the idea of putting a few chips in every device. It becomes almost the same arguments that everyone has against USB stick miners, with the addition of not being able to actually play with it making the idea less attractive. One main concern I have is that the manufacturer won't tell the customer it's in there, and the customer may not care to spend the extra $2 a month in power even if he knows about it, but that's fairly evil by my standards regardless. Then there's the concern over locked pools. If you can find a more efficient, reliable and still actually fully usable way to make a miner than to actually make a dedicated miner, sure. But if companies can hide things from their customers and thereby increase profits, odds are good that they will. I also don't mind seeing big farms take a hit, but I don't want to see them take a hit because they're being replaced by big dispersed farms with no power costs. But there's plenty of that discussion going on in at least two or three other threads already.

 I have three pieces  APW3-12-1600 PSU.

 APW3-12-1600 do not have power switch.  I do not like that.

APW3-12-1600 powered up 3 x Antminer S5 and this is good.

any idea of efficiency ?  

 I was afraid it would be short   of power to do 3 s-5's at 1150gh freq 350  .

 Please post details if you can.

Tried it only with one PSU of the 4 hours, and is efficiency is not  bad.

1700 W at  223/216 V

Bad was miners GH/S(avg).  
In this you are right. It would be short   of power to do 3 s-5's at 1150gh freq 350  .


1575W at freq 325

1450W at freq 300

1610 W at freq   331,25M

Or most folks already are well stocked with HP and/or IBM server supplies to take care of immediate future needs (like me)  ;)

But ja, unless folks have several 'spare' kw to use at home and a way to take care of the heat, home mining could well be kaput. Now, that doesn't mean that the only customers left for Bitmain and any other mfgrs still around will be only Peta-farms, just that it's now past the hobbyist stage and in the hands of folks who can afford & locate larger setups.

yeah for me I have summer rates of 16.9 cents add in 1.1 cents and at 18 cents home mining is done until oct 1  rates drop to 13.3 cents and with the heat made take off 3.3 cents and from oct 1 to june 1

 I am at 10 cents.

I have 1 spot to mine at 3.2  cents in the summer and 2.4 cents in the winter but my max power there is 1kwatt.
I am running 3 s-3's slight under clock.

any other renting is from rentals see sig.

please note my sig is a gift to west-nice hash and ck solopool

Heh heh.. I'm one of the lucky ones. I pay 15 cents kW-hr at home where I run 4.4Ths but at work my electric used for miners is 'free' so have 28Ths running there.  :P Our light-industrial rate there is 7.5 cents/kW-hr.
Nice being one of the owners ;)

Is this plug n play, or am i going to get this and have to go buy a power cord for it?
im in US, so i assume i am ok with the 205V minimum?
Thanks

As Bitmain states in the product description, we need to supply our own cord.
Gets them off the hook in supporting the gazillion different national plug types out there.

If you are willing to cut the male end off of a 14ga 110v IEC cord and replace it with a 6-15P that can be used. Barring that try Amazon/eBay or here http://www.stayonline.com/208v-straight-blade-cords.aspx (http://www.stayonline.com/208v-straight-blade-cords.aspx)

With being in US you would need to check and see to make sure your above 110/120.  It warns if "The PSU cannot be used in countries with a mains power voltage lower than 205V. The PSU will not start below this voltage."

Be careful (call electrician if feel uncertain with electricity).   But you can tell by looking in your breaker box and looking at the breakers. Specifically the breaker being used the the area where this PSU will be plugged in.  For myself I had 120 and got 240 added in via a new breaker and wire. 

Which would you use to replace the PSU that has stopped working in an S4. The PSU is connected by bolts to the board not a PCI

DPS-2000 + breakout board + S4's cables. You'll have to check if the breakout board has a limit per wire channel, I don't remember one.

Ohh dog-ie. You produce a pure loss for your  owner Bitmain with your barking.  

BITMAIN AntMiner APW3-12-1600 PSU Series  hat is own separate power board to connect the PCI-E cables with S4 cables.

Named S4 Power_Board V1.0

wtf am I to do with that?

I just ordered 4 new S5's, (which im going to assume they were running, because they do not look fresh off the factory line- but they hash  ok i guess) and also 2 of these PSU APW3-12-1600-B2 from bitmaintech. My third purchase, after the S3 and S5's i already have.
My issue is that upon pluggin the psu in, the fan comes on, but fails to even light up the S5, which i checked the actual s5 unit with another PSU i have working on another S5 that i already have. How possible could it be that i had 2 BAD PSU sent? Odds of that are wierd.
I sent a ticket in last night and this am woke to this:
Hi,
please confirm what's the voltage from the wall in your side.
The PSU cannot be used in countries with a mains power voltage lower than 205V. The PSU will not start below this voltage.
Please confirm whether it's due to this issue.

I wrote back that im in the US, upper middle class neighborhood with a house built in the late 90's.
Power is fine on my side, even as i told them that the unit works with my own PSU's and not my power issue, but a FAULTY PSU by them.
I hope they pay for the freight for return and EITHER A REPLACEMENT AT NO COST TO ME, or just give me back my frickin btc, ill go back to using the 750W like the other 3 i have working just great.

- AS OF RIGHT NOW, I GIVE THESE UNITS A FLAT THUMBS DOWN. well see if that changes with the Bitmain Customer Support.

-For what its worth in my two cent mining ops
:)

An upper-middle-class house in the US will not have 240V common circuits, no matter when it was built. DId you wire in 240V outlets specifically, or are you running it off a repurposed dedicated AC or dryer plug or something?

I assume you have tried taking one of your "new" (i.e. recently arrived) S5's and swapped it in place of a working S5? You just want to make sure that the S5 is functional, and not a broken PSU.

Sidehack is very right with most US houses they normally do not put in 220/240 for devices unless you had asked when being built or added it on.   Chances are you have a outlet that's 220/240 for your washer/dryer and maybe a stove depending on settings.

But you will need a 220/240 breaker with higher guage wire installed most likely to mine with the PSU's.  They need the extra power to be able to boot up, that's why warn about "The PSU cannot be used in countries with a mains power voltage lower than 205V. The PSU will not start below this voltage."

As always be careful with electrictricity but if you have a nice power multimeter you can tell at the outlet what it's putting out.  If you do not have one you can tell by finding the breaker used for that outlet.

sounds like you dont know the difference between 'MINIMUM OF 205 VOLTS' and a typical 115V outlet.  obviously a 240V-only device wont work on 115V. Thats like trying to plug in a microwave to your 240V dryer outlet (hint: it will probably release smoke)

please confirm that you are either using a correct outlet, or simply did not read the PSU description properly before ordering

http://www.lowes.com/pd_246702-1571-L630-RCCV3_1z0yt2jZ1z10vpr__?productId=3537736&pl=1
 usa 240 wall plugs look like this.

As others in the thread stated, your issue is likely due to insufficient mains voltage.  If you're interested in platinum PSUs that will work for you, check the link in my sig.  Two of the 1100s will power 4 S5s and will run on your residential 120V power just fine.  Highly recommend you put them on two different breakers, however.

Please shed some light, I just wanna know if I'm gonna use this APW3-12-1600 PSU to my antminer S4 (Terminal type) the 1st batch of S4, there is a big difference when it comes to the switch of power supply.
My question is how am I gonna power up this power supply without power button, unlike in my 1st batch S4 it has a builtin power switch with the PSU.

Thanks & best regards

kae1078

Its auto on, which means when you provide it mains power its already on. Think of it like a phone charger, if you plug it in its just on.

Thanks dogie for shedding some light, now I just need to order from bitmain since my s4 has been down for almost a month.

Please make sure your miners are using 205V or higher at the power outlet. 

Normal USA 110-120V outlet will not power this PSU on.  Minimum Operating Voltage is 205V.

Yeah I'm sure, I make sure of that.

Hi,
I wanna buy this for my s5's.
Is this compatible with s5? connectors and efficiency? I have 10 s5. 5 psu is enough for them ?
and it really auto turn on ?

they should work if you have 205 volt or more power in your home.

where do you live?  If in USA most homes do not have 205 volt power they have 120 volt.

Probably should clarify that some, it's fair to say all US homes have it however it's generally limited to appliances and the like, meaning you can have a circuit dropped in pretty easy..

thanks. I have 220 volt
most important thing for me is auto power on. i have a few s4 in a location and every time the power is disrupted they require me to travel about half an hour to press the stupid button to turn them back on.

Yes these are Auto Turn-On

Is it possible to adapt this PSU to fit the older style S4?

Not with the PDI connectors but with the ones fitted with a nut and bolt?

yes but it would void warranty if you do it.    (not sure but I am guessing I am correct)


wait for dogie to confirm.

Yes. BITMAIN AntMiner APW3-12-1600 PSU Series  hat is own separate power board to connect the PCI-E cables with S4 cables.

Named S4 Power_Board V1.0


https://i.imgur.com/tmMMvNO.jpg (https://i.imgur.com/tmMMvNO.jpg)

but you still need minimum 210V

Oh OK so you take the cables from the original PSU connect them to the board in the picture - how using the screw connectors shown in the picture?
Then connect the PCI cables into the board?

Does this board come with the PSU as standard?

Thanks?

Yes.

OK thanks but - connecting the cables do the old style ones connect via the phillips screw I can see in the image?

ta for your patience!

Just to be totally clear, if you have an S4 and you buy this psu everything to convert it to the ring/terminal connections from pcie is included or do you have to request v1 when ordering?  Thanks... this shouldn't be this confusing but I hate to open the package and find out it has the wrong connections. :P

Thanks

I would like clarification also :)

It would be nice if Bitmain could review their own threads and answer some above questions asked.  You would probably get more sales that way.
Can you answer these questions above please.

I think they want you to go to their ticket system.  I would like it to be on forum aswell.  But I am just a little guy :).

Go put in a ticket for quickest help.

I have but the answer I got was simple to say the least and unclear if everything to power an S4 with ring terminals was included in the B2 model.
They stated something about the B1, but there is no way to order that from their site.  Sometimes it would be nice to order by phone in these cases.  I will try another ticket, thanks notlist3d.

Just for the record this isn't me you're waiting on, Bitmain replies will come from the BitmainWarranty account. There are a lot of threads though so they may not be checking all of them on an hourly basis. My information regarding the APW3 is also from release time so things may change.

How about you or Bitmain comment on the S2 upgrade kit?

That's up to Bitmain.

I think the no comment speaks for itself.   It has been asked many many times.  There are a few pushing it up every few day's.

I would not count on a upgrade kit.   They are secretive on a lot but I think they would respond more recent if they had plans of even looking into S2 upgrade seriously.

Dogie, it wasn't directed at you.  I know you can only comment on what's allowed or known.  But one thing you can help with is getting better clarification on this psu for us.  I've contacted support but there answers are vague and I'm left back where I started.  This is what you are here to help with since you can put it in terms we understand not operator answers like "It should work, just buy it and see".
Again the silence is bothersome and in the past it is a known sign that something is up with many companies.  Our point in this forum is to address issues that could easily be adverted by the simplest tasks, it's just damaging to a company not to listen.

All I wanted to know is if the B2 model of the psu will work with the S4 without additional wiring.  The 10 gauge wire with the hoop terminals.  My reply from Bitmain was to use the B1 psu but it isn't listed on the website so how do I acquire that?  It lead me to believe also in another reply from Bitmain that both sets of wires are included in the B2 psu.  So which is it?

Contact their support through a ticket: https://bitmain.zendesk.com/hc/en-us

They can help you get the PSU for the S4.  This psu they are selling is a good psu, but requires OVER 110 electricity.  So if you are running 110 yes you need a different PSU then the one this thread is for.

I have and I'm still waiting for another useless answer but I will play the game again..... but I'm running out of quarters!

Are you on 110 or 220/240? 

If yes on 220/240 sure buy this PSU.  If running 110 NO do not buy this PSU and buy from their support.  No more quarters needed :)

Nothing else, buy this PSU, cut the cables off, twist-lead and bolt the wires directly to the S4's rings. Take about $1 in hardware and some good electrical tape.

I don't believe you can buy from support, ie old psu on 110v ever since the new psu was released, but I may be wrong.

Thought about it but I'm looking to resell it on Ebay and didn't want to "hack" anything although I know it would work. 

I have 1100w Platinum PSUs in my sig that can output power over heavy gauge 12V cables with ring terminals on both ends(can give you the cabling for free with purchase).  However, it may not fit quite right in the S4 case, I'm not sure what the form factor is(mine are 1U units, 14.28" L x 2.15" W x 1.57" H / 362.7mm x 54.5mm x 40.0mm).  If you can't get anything figured out with Bitmain PM me, I can probably help you out.

I will research it this weekend.  Thought to inquire this with you a month ago but I am looking for a solution that will fit in the case as I'm planning to resell it.  Thanks I will get back to you.

What would you take for it without a PSU?

@notlist3d - Have you tried anything from the link you posted?  Seems like a dead site unused for months.  Maybe Dogie can agree, is Zendesk an old site and should all correspondence be through Bitmain's main site?

I will pm you since I noticed what you posted in the S2 upgrade thread.  I have an S2 complete and 1 S2 no psu with 1 bad hashing board left.  Wanted to keep 1 S2 just in case (By an act of God) the S2 kits were released.  I needed it for a review.  As well as the S4 with a psu that seems to be unable to output more than 1100 watts without resetting and is unable to handle undervolting.

It's been maybe 2 months since I had a ticket on it. Was dealt with fast though back then.

It should not be unused, I believe it is most current way to contact them.   They did email at one time but I thought it moved to this.   And it should be maned... if you are not getting a response I'm not sure what is causing that.

But my advice is sound if you have 220/240 yes you can order this and use it.   If 110 no do not order this as it most likely will not even start on 110.  For 110 you need them to help you get OEM of old PSU, unless you use something else.

I'm not contracted by Bitmain any more, so I'm in the queue for information with the rest of you.



Zendesk is the US team, Bitmain site is the CN team, although US team usually takes the tickets from the Bitmain site and actions them via Zendesk. Go to Zendesk.

The link is old and no current info from the Zendesk site, click it and you will see.  As far as getting anywhere with support, previous talks they pointed me to the new psu.  Nothing was said about any support for exact replacement, seems they don't keep much old stock around or are too busy devising new or should I dear say remodified hardware.  But that's my exact point, after warranty period I don't think they care what happens to our heater paperweights.  But I digress.

Edit:  Zendesk did work and responded within 1 hour, amazing.  Still communicating to resolve my issue.

Send in a ticket don't take the front page info as your reference.  Tell the support you have 110 and do not have 220/240 and I think they will arrange to sell you a replacement PSU pretty quick.  Use a ticket and tell them you have 110 and need replacement.   

And it depends on model.  S3's they have controllers and parts for (last I heard). But ones like C1 that were much more limited they did not have parts (last i heard).

PSU APW3-12-1600-B2 can be used on any version of S4 with some may require cable modifications with the breakout board.

1 string attached with the PSU APW3-12-1600-B2 is you must have 208V or higher.  (205v or higher) to be able to use it.

If you have to use 110v, depends on the condition of your PSU, centers in Denver, Ukraine or Serbia may able to repair it for you.  If it still powers on and gives you some ERROR LED Status. 

Support@bitmain.zendesk.com is the route to request servicing your original S4 PSU if it is not completely dead yet. If the fan won't power on, or no LED light comes on, then it is not serviceable.

Unfortunately at the moment, S4 PSU is not in stock.  Time to time, the centers in USA/Serbia/Ukraine may have those in stock so please keep checking with the supports

Thank You... In talks with them now, may send the whole unit to them for problem solving.  Again Thank You.  Although the page looks outdated and blah with little to no info techs responded promptly from US Zendesk.

Is noisy these psu?..???.

It is a server psu.... and 1600 watt's.  I think it is safe to assume it makes some noise :).

Normally when you look into most server PSU's noise is not a huge factor as far as what they worry about.

If you want something that's platinum and enterprise grade but isn't all that noisy, check out the 1100s in my sig.  Fan adjusts with load.  If you run it at max or in super hot temps it will make some noise.

Also see J4bberwock's 2880W IBM breakout boards as linked in my sig for North America.  Will power 2x S4's (externally) with a power harness, 80+ Platinum rated, etc: https://bitcointalk.org/index.php?topic=1036295.0

I use DPS-2000. They come with no fan and you have to add cooling yourself.So I can use whatever cooler I want.Ofcourse I had to modify casing to fit the cooler but these are good psu's and they are cheap.

OK so I sent my S4 PSU to Serbia for fixing came back fixed and worked for about 10 days then same thing. Machine off with ERROR LED status.

Is it a reset that can be done easily - as it costs a small fortune to send to Serbia from UK. If how? Looks fine inside :)

Re the PSU APW3-12-1600-B2 I notice in the pdf manual it offers 2 types of wiring Type 1 : old type with M4 ring connectors and Type 2 PCIe type

Is this provided? - if not what did you mean by cable modifications with breakout board. Is it as simple as unscrewing/unbolting the PCI cables from the position shown in the image showing the cables and replacing with the original cables from the old PSU.

I'm looking for an S4 with dead PSU. would you sell yours?
Shipping to France.

Not at the moment  ;)

Probably deliberately drilled the whole so they could have a moan

Be prewarned.  My S4 just came back from Bitmain Denver from repair of psu and worked for 10 min before getting alarm light.  Now it doesn't power up.  Seems they are replacing these with used psu's and after $200 spent including shipping I was expecting the psu to be replaced with the 220v new model psu for that price.  Now I'm sending back the psu again since they said they would warranty it for 60 days.  It came back dusty as hell.  Was totally clean inside before repair and pool info switched to theirs.  I sent it to them for repair not to mine their own pools with.  At least if your going to test it let it mine my pools Bitmain.  Another week wasted. 

Doesn't sound good.

I only sent the PSU - have been told by Bitmain that the APW3-12-1600 PSU Series will work with any S4 provided you have the right voltage 205V + - waiting for confirmation that adapting the cables is possible to do properly - not with plastic tape and solder

Yes it will, but moving to that voltage for most means moving it in your kitchen or laundry room.  But the old psu ver. 1 and 2 suck d!c4.  Only viable option is the apw3-12 until J4bberwok gets his working solution.  We want a psu that fits in the case not outside.  Mine will be sent back to Denver, this time just the psu so there's no funny business.  I will demand this new psu since they seem to replace warrantied psu's with used stock.

I'm in the UK so no issue with the voltage all 240  ;)

Dear All

If thinking of buying this PSU for an S4 with the older M4 ring terminals, this is the reply I received from Bitmain.

Hello sir,

when you are making order,

you need to make a comment that you need M4 ring connectors. that way factory will prepare everything and ship.
but please be sure that they have understood you fully. and that you do not need bunch of 6 pins.

send them a picture if needed, that you require type 1 (m4's with one 6 pin). or red cables.
just be crystal clear. so they do not mix order.

Hope this makes it clear how to order

good luck

I just received my APW3-12-1600 PSU that I want to connect to my S4 that has the M4 ring connectors.
Even though I mentioned this when purchasing as suggested by support the PSU arrived with PCI connectors.
However I did come with a power adaptor board.
Can you send me instructions as to how to connect the original cables to this board.
Also the APW3-12-1600 PSU has 12 PCI connectors and the board has only 8 connectors.
Which ones do I use - some included instructions would be helpful or put it in the manual

Just sent this message to support.

The saga goes on :(

Thanks

So doesn't matter which ones you pick??
The controller is the one PCI that fits inside the box sited the back of the original PSU?

I knew that would happen with your order about the connectors.  That is why I held off.  They tell you to let them know that you need the ring term connectors but there is no place to do that when ordering that I'm aware of.  And that they would install them for you.  Does it fit ok in the case?
The controller is the board that is in front of the psu and has the one pci-e connector.

Can't see how it can with all the wires and being a bit longer as well. But the section is a smaller.
Not bothered as long as it will fire up.

Notice that have recently put this up on the purchase page:
4. If you need the PSU to replace the one in S4/S4+, please kindly mark "need the switch board to use in S4/S4+" in comment field when placing order, we'll add it when shipping out the PSU. Otherwise, it'll not be included.
No instructions on how to wire it up though.

But S5+ available needs 3 of these to power it !!

Thanks.  When I looked in the past they didn't have that option.  Yes, the S5+ is a beast for power.

You any idea how to connect up this 'switch board'?

What remains unclear to you?
S4 Power_Board V1.0

https://i.imgur.com/tmMMvNO.jpg (https://i.imgur.com/tmMMvNO.jpg)

From left to right + -  , + - , + - , + -

OK I maybe thick but here goes  ;)

Any 8 PCI's from the PSU can fit in the board?
Any of the remaining 4 can fit in the controller?

Using the old cables from the PSU - do I separate all the cables strip each end and fit them in board as indicated?

Any cables can to to the blades as long as they are gnd to gnd and 12v to 12v?

Or is there a specific order?

The server psu has one rail I believe so it doesn't matter in what order you hook up the wires unlike some atx psu's.

When you do install it in the S4 could you post a pic.?  Interested in seeing how well it bolts up to the case.

Edit: I receive mine on friday and will post pics of it and how it fits in the S4 case this weekend.
I may make a faceplate to help it mount to the case in the coming week.

Well received the APW3-12-1600 in exchange for a non-working replacement they first sent. It is long, don't think for a minute of bolting it to the case.

Mine was sent from Denver and had the ring terminal connectors already installed - Thanks Yoshi!

Originally thought of mounting it on top and placing a bracket underneath but as you see
it fits so tightly in there that the ribbon cables have no room to run to the top hashing board.

https://i.imgur.com/xTWh98Cm.jpg

I will just settle for now laying it in sideways and having it hang 2" past the case.
note:  The mounting holes on the psu in no way match the case.


Question?  The psu came with no cord.  I'm no voltage expert but wondered what cord do I need to plug this
into my dryer outlet or adapter (220v).  (I know not to run both at the same time) but for testing.  The psu itself takes
the similiar type size as any psu but are there differences I should know about?

I was surprised with it's compact size.  It is long but not tall.   Just when I opened it I was expecting it to be more boxy i guess.

I would suggest getting a cheap PDU.  Go from PSU to PDU.  It works very nice and gives you space to put multiple easy.

Are you able to take a picture of your outlet? 

Mine arrived from China with all the PCI cables despite asking for ring connectors

Have wired it up using the switch board provided and it works fine - now looking to tidy up the cables and find place to position the power unit.

Will post photos when I get it done. was thinking of fixing it to the outside - however seeing Meeches attempts might see if it will fit inside somehow

Here is my dryer receptacle and plug, I believe these are US standard.

https://i.imgur.com/oSDjsD3m.jpg                   https://i.imgur.com/7mNxOEVm.jpg


I was looking at this Pdu from CL which I can get for $25:

http://www.amazon.com/Compaq-Power-Distribution-Voltage-NA-only/dp/B0007RAOX4/ref=sr_1_1?ie=UTF8&qid=1440215910&sr=8-1&keywords=compaq+pdu (http://www.amazon.com/Compaq-Power-Distribution-Voltage-NA-only/dp/B0007RAOX4/ref=sr_1_1?ie=UTF8&qid=1440215910&sr=8-1&keywords=compaq+pdu)

It's 16 amp max.  My question is it comes with the twist-lock plug is there an adapter so I don't have to change receptacles?  This is temporary just to test this S4.  The pdu's all come with a different style plug as well, do I need a special cord from psu to pdu?

Edit:  Found some of my answers.  I have an older house so I have 3 prong 220v outlet for my dryer after 2000 all homes were wired with 4 prong outlets per standard.  Found adapters from psu to pdu (C13 to C14) and a 3 prong to 3 prong twist-lock adapter, which most pdu's seem to have.  But what I need to know most is does a 220v pdu output in 220v or is it 120v?  My APW3-12-1600 only runs on 205-240v.  Any help would be appreciated.

I can't say for sure all PDU's do it.  But yes a 240/220 PDU putting out 220/240 is kinda the point.  You want access to a lot of power.    

How many of these do you plan on running?  If multiple you might see how many amp your breaker is putting out to the PDU.  I know when I put my 240 in I specifically went with 30 amp breaker to get a good amount of electricity through it.

It's a 30 amp breaker and this is temporary just so I can test this Bitmain psu.  I will get the pdu off of CL and the adapters needed and try it in a day or two.

Here is  the full review of this power supply on CYBTC English site

http://www.cybtc.org/article-86-1.html

This is confusing, Dogie said that he could not notice the fan noise at all with this unit? So which one is it? I would really like to know how loud this unit is. Would it be as loud as the S5's fitted with custom fans?

I have one hooked to my S4 and the high whine can be heard above the S4 fans.  I believe the back 2 fans on the S4 are the same used on the S5.  So yes it can be heard. 

Thank you, that is what I wanted to know.

Apologies if this has been asked/answered already.

I have a 220V plug in my basement where I will run my new S7 + APW3-12-1600.

But the 200V outlet I have looks like the kind in laundry room, i.e. a round outlet with non-standard plug sizes compared to a regular outlet.
Like this: http://ask-the-electrician.com/images/DRYER-3-WIRE-OUTLET.JPG

But does the PSU come with a standard computer power cable with a regular 3-prong that goes in to something like this?:  http://wesellit.ca/m/image/catalog/products/waterstar_3person/feature/standard-outlet.jpg

If so, how would I make the square peg fit in the round hole?

:)

Only good things to say about this PSU.

Outperforms: (Meaning a little higher output voltage, 0.1-2+)
Corsair 1200AXi
EVGA 1600 G2
XFX 1250

My S7's run very good on this PSU.

You can buy a laundry cord like this at the hardware store with bare ends and then buy a 20-30a socket with lock.  Then purchase a power cord that fits the psu and other end that fits the locking socket which you can buy online.  If you plan to run multiple miners then a pdu would benefit you.  The latter cord then would need to fit the pdu.  Exact cord and socket types I'm not able to provide right now, I'm away from my computer.

Guys, trying to Run 2 EA S5's and 1 EA S3 off a single PSU 1600 from bitmain, this style on thread.
Is this too close and wont hold, in your opinions or anyone else try this?
S5 PSU is 590W at wall, and S3 is 340 total is 1520 W
So it makes sense to me that it would work?
If so why not?

Thanks

On a 1600 watt PSU you would be pushing it pretty dang hard to run at that load.  I would personally do lower.

Or you can underclock so that they use less.  With unerclocking  you for sure could do all 3.

FYI -- I ran a 20amp double 110/120 breaker = 240v to a dedicated receptacle with a standard 3-prong U.S. plug outlet. Then a standard AC power cable (for PC's etc) to the unit and it runs fine. Easy to do, and works well.

In the Notes for this PSU on Bitmain's site it says:

1. The PSU cannot be used in countries with a mains power voltage lower than 205V. The PSU will not start below this voltage.


My 220V line reads 202 -204 at the wall/socket. Will I have enough voltage to start this PSU?

That should be within tolerance, but I can't guarantee anything. I'd try it and if for some reason it won't start you could resell it as new for almost what you bought it for. 200-240V power is what you really want for your miners so its worth giving it a shot. These are good PSUs and you'll be glad if you can get it to work, plus you'll be able to draw almost 2x what you can using 120V and get a small energy savings to boot.

Thx- was thinking the same thing. Just not keen on having to resell if it doesn't work. However, if that's the worse case, not a bad one.

The time to make corrections.


No more S4 Power_Board V1.0 breakout boards with new PSU.
My last bought  4 x APW3-12-1600-B2  came without this breakout board.

And dogie does not work anymore for Bitmain, which of course is not something strange. .
Free land. dogie  are now more committed to the Forum.
Read more doggie doings of my signature.

Guys, is there any way to reduce the fan speed of this PSU? It's a tad too loud, a kind of weird noise for using at home 24x7.
 One option that I am thinking of would be to cut the fan cable and insert a resistor in series.

Peek inside the PSU

There's a Vadj pot at the bottom. The max output voltage is around 12.6V. Need to remove the screws holding the PCB to get access to it.

https://i.imgur.com/Bpw6UhF.jpg<== 56Ohm resistor to reduce fan speed + noise

good info  12.6 volts max is very good  that makes this a decent option for the s-7

Nice job on spotting that.  Interesting that they have it hidden in there.   I do like that it's there.

They have made it pretty much the best out there for the S7  with those 10 PCIe cables needed.  Nice to see a little secret to their PSU.   It's not a bad PSU at all if you have 220/240.

Well that's handy. Have you also checked how low it will go?


Rich

Good question mate, IIRC approx 11.5V.  :)

Yup cool  :), hope this will help someone.
Bitmain should do something about the PSU fan speed. Maybe, make it automatically ramp up / down with temps, or add some kind of user adjustment.

I have a question, I bought 3 x psu from bitmain, but must arrive. my question is:

They are noisy?
They are supplied with power cable? ???

They are not quiet with the little high RPM fan.  I don't consider them quiet.

No cable comes with them, you need to order what ever cable you need.  There are a few different ones really not all PDU's use the same cable (assuming your using a PDU).

1300W correspond to how many amps? :-[ :-[ :-[

If Amps IN = 1300 / Mains Supply Voltage

If Amps OUT = 1300 / DC Voltage (12V)


Rich

I can not find a pdu to power 3 X S7 with 3X psu from 1600W bitmain
I have a section of single-core cable 6 mm, with a magneto 32 AMH

I would think a 30 amp pdu could handle the 1400 watt x 3 pretty easy.  I know I had around 4800 watt's I believe on mine and still had amps to go with 30 amp pdu.

But of-course you need a 30 amp 240 breaker in there as-well. (Or that is how I'm setup at least).

Any chance to test output voltage where undervoltage protection shut down PSU? It could be very good PSU for S5 and first batches of S7...

Does this power supply start up again after power failures or blackouts?
Normal ATX PSUs need to be 'activated' after a power failure with your switch or bridge wire.

it has a bridge wire so it fires up after a blackout stops.

It is 240 volts.
It is loud.
It has a hidden pot for voltage adjustments.

I have found a sale and a low cost (170 usd after rebates)   good quality (evga) 120 volt solution

see link

https://bitcointalk.org/index.php?topic=1308428.0

That is great. S5 keeps powering off when power failures occur on site. ATP PSU does not start up automatically.

here in RSA we are using 220-240V.
The sound i am going to have to make a plan with all depending how over powering the sound is compared to the S7.

certainly sell power supplies without power cord and poor homeless

shame ??? ???

To be fair I think it makes sense in this area not to sell the cord.   There are multiple different PDU connector types..... so what should they do ship one knowing it does not work with all?

I think this makes sense don't charge me for the cable.  And I can buy on amazon to fit my PDU's needs.   If it was a 110/120 I could see your point but with this going to 220/240 on most I don't think they did anything wrong not including cable.

cable 110/120
cable 230/240

simple?

Cord pdu buy,
but at least the power cord for their products may be included in the package.

I tried on ebay, amazon, you do not meet my needs,
They are all of diameter 0.75mm
I have seen no cable psu from 1.5mm.
then I bought:
3x 1.5mm cable
connectors for power psu
shuko plug

Yo notlist3d.

Were is the volt manager? and what is the max output voltage ?.

I got one for my s7 b6 and wanting to overvolt som as the b6 is pretty much lowered.

How could i do it ?,what is minim and max  volt output from this psu ?

Look back in the thread a bit, can adjust from 11.5V to 12.6V.

Yes, i was just checking the pages, you were faster.


I've seen that S7 Likes 13 volts in some treadh , should not be problem to overvolt then to 12.6 and plug to my s7 ?

S7 spec is 12.6V, so is fine. remember overvolting an S7 only applies to Batches 1-5 & 7


Rich

Why not b6 ? :)

Because 6,8 & 9 have a Buck Converter fitted, so there will be no effect. There will be a way of adjusting the Core Voltage on these without touching the PSU, but it has yet to be worked out. I do not have one so cannot help.

Rich

Ok i readed all your post richB regarding the volt.*


So it's fine to put my b6 to max volt of the Antminer psu tp 12.6 , and up to 13v wich it dont suppport, it hsould not damage anything?.-

i should stay out of 14v in other words as there havent been any testes.


Wich side to i turn it clockwise to step up the output voltage?.

Ah okey damn , i am being slow even to read.




So if it runs 11.5v or 12.6 it wont make any changes it will just stay always at 4050 then in other words :)

The Buck Converter in Batches 6,8 & 9 will regulate the voltage to whatever Bitmain has set it to. Not sure what you mean by 4050?

Rich

I just got an antminer psu, so i am guessing its not on the max volt i think th ey come 11.9 ?  .

I meant if i regulate up the psu to 12.6 it won't matter as the hash wont go upp ?.

Correct, hash will only be increased by pushing up the frequency, but need to check HW errors & temperatures.


Rich

Yeah, i will try to max the volt, and ill come back , as at it is sitting, if i go 606, my hash drops to half .

but feeders bitmain what are they?
bronze, gold, platinum?

Ok so i  was turning the knob but it dont have a stop, it go all the way around.

*i noticed that the Screw is not totally ciruclar.

Were should i place the " LINE" that is there.

I dont have a meter on me right now, and its to late to pick one up.

I would put it in the middle of it's travel. The "Flat" needs to be aligned with the 2 pins at the ends of the pot as opposed to the single pin opposite them. If in doubt wait until you have a meter to measure the voltage.

Rich

Upp like the red line is what you mean right , if i understand you correcct?

At this moment it is at the Purple mark, and i tried 612, and is actually more stable than before and less errors.

Ill wait for your response to disamble again :)


On the side atm it is running abit colder aswel less 5c on the temps . hmmm  ::)


http://i63.tinypic.com/207oqcx.jpg

I cannot positively confirm as I do not have one here to check. I would wait until you have a meter and set it properly rather than guessing.

Rich

alrite well thanks for your help, ill be picking the meter tomorrow and ill update how it whent.

do not buy this crap unless you have really good fire insurance.

totally uncalled for useless comment. Thanks for contributing to an otherwise decent discussion

Did one catch fire recently?  ??? ???

Hello everyone! I registered to ask this question because Bitmaintech lets me wait more than 40 days for an answer to my support ticket....

This is my question: How many Antminer S7 units can I connect to one unit of this PSU? Physically it seems that you could connect at least 2 pieces of S7 to one PSU. Does this really work or is it unwise (overloading, fire hazard etc...)?

Thanks in advance for your answers!

Bitmain clearly says that ONE APW3-12-1600 PSU for ONE ANTMINER S7. And there is no extra PCI-E connectors.
See https://bitmaintech.com/productDetail.htm?pid=00020160129054250700R0OMI3KI061A

I have to ask what is your voltage in your place to mine.

You need 205 voltage or higher to use this psu.

where do you live?  as usa is 120 voltage.

Yup only one S7 can be powered by a APW3-12-1600 PSU. There just enough connectors and power capacity for a single S7. http://2.bp.blogspot.com/-dBrvVukrBJk/VmOCabuKaSI/AAAAAAAACV8/CbURVt6XlN0/s1600/DSC06723.JPG

Didn't they come with 12 at one point?

https://i.imgur.com/7wEBQDm.jpg

Image in the first post says 6 pairs of 6.

Typo IIRC

I THINK IT WAS ALWAYS 10

So more false advertising that they don't want to correct.  Gotcha!

The first 2 I got from Bitmain have 12 PCIe connectors. Also no provision for DC on/off unless there is a header inside. Now they all come with 10 PCIe and a DC on/off pigtail  plug w/jumper on it.

Thanks for the clarification.

np. Think my first 2 were from late batch 2 or early 3. I was luckily cautious enough to sit out the first round of them.
Since the s7's came out they are all I use. Most of my HP 1200w PSU's got sent to sidehack to run the s5's I have hosted with him and the my IBM PSU's are in use here.

Just got simpler to use something premade for the job. So far zero problems with now over a dozen of them.
I really have to update pix of the main farm. This is pre-s7 days http://phluph.imgur.com/all/ (http://phluph.imgur.com/all/)

The area looks downright barren now but has more hash power yet slightly less kw used than what it took pre s7's.

I have 3 originals from S5+ day's with 12 connectors.  It did not need more then  the the 10 but it did have it.   

Not sure what caused them to remove it.  Although they might have decided 10 is  all they will use and that is quite a bit.

Can anyone verify the power factor on one of these? I'm wondering if the one I tested is defective, or if they're all crap with a PF of 0.93.

I always struggle with pf vs efficiency

 These are supposed to be 93% efficient platinum.

So what are they?

I know the 2880 IBM psu is gold at best
Th 2980 IBM psu is a platinum.   

Both my test on them were done with stock fans and with my fan mods

Stock screamers use 60 watts, my mods use 25 watts.

So does pf = eff?

No 2 different things although PF does impact efficiency.

Power Factor is how well the load compares to a purely resistive load which is a PF of 1.0. A purely resistive load has current draw exactly in-phase with the voltage.

Toss in capacitance or inductance eg. the cap inputs to a switching supply or a filter choke and current then either leads or lags behind voltage. Normally not an issue for users but when you start running heavy loads like several 10's of kw -- then the power grid starts to complain because the out of phase current draw will start to become much higher that what the average current reflects.

PF can either be passively or actively corrected in a PSU. Passive correction works at the expense of overall efficiency, active control is more efficient but costs more to implement.

EDIT: All about PF http://powerelectronics.com/power-electronics-systems/back-basics-power-factor-and-why-we-correct-it

What power cord do you recommend to use with this PSU?

At least 3x1.0mm2 power cord with C13 connector in other end should do.

if you are usa based 16awg  is thick enough since it is 240 volts.

I like 14 awg

I noticed that there is a new version of the APW3 PSU at cnshop.bitmain.com

Hi, i just got this psu today.
Initially it run for about 20 mins, then it shuts down and i am not able to get it back up. Things i have tried as below:

1) Used different power cord.
2) Used different PSU to make sure it's not the miner that faulty.

You're using it on 205v or more I assume?

yes my country standard wall socket is 220-240v.

It works initially for about 20 minutes. How do i troubleshoot this? any internal fuse or something?

If you are not experienced with servicing electronics DO NOT OPEN IT OR ATTEMPT TO SERVICE ANY PSU! The line power side can at best give a heavy poke and at worst KILL YOU.

I assume the fan runs and it does not get warm/hot? If it simply shuts down and is not being overloaded then time to start an RMA with Bitmain.

The fan run and the miner hashing for only 20 minutes then it stopped completely and i am not able to turn it ever since. Currently using other psu(not bitmain) to run my s7

Again, file an RMA with bitmain. I have dozens of the supplies and many are several years old -- zero failures. Once Bitmain fixed the problems with the batch-1 supplies they have been pretty bullet proof with very few reported failures.

Just to be clear in how this was calculate:
In 1 hour = 1.6 kW
In 1 month (744 hours) = 1,190.4 kW

1 PSU in 1 month @ USD$0.10 per kWh
1,190.4 x 0.10 = USD$119.04

Are my assumptions correct?

I'm searching for an pdf or som specs on the U10 chip:
8233BD
1534DFL0DU

I think it is the switchmode controller in the APW3-12-1600-B2 PSU?..  ???

One of my psu died when the temperature in my mining house dropped to -10c.. is there any drawing of the board and components? The DC bus is ok, the 12v low current supply is working, mosfets and diods seems to be ok..  :-\

i can't get the differences between those two.
one them is 5 pairs pci-e other 9 pairs
all numbers are same max output etc
5 pairs one is for s9 l3 and d3
9 pairs one is for l3 only ??
any idea prices are $105 $115

More cables, more price.

They are both the same power supply.

But you must understand that the one with 5 pairs cables (10x cables) is good to power ONE S9 or L3+ or D3.
The one with 9 pairs cables (18x cables) is good to power TWO L3+ or ONE S9 or ONE D3.

Thanks HagsFIN
unfortunately i have 5 pair cables batch 20 pcs
any way to convert 9 pairs pci-e ? any one know this ?
edit : just checked one of them no way i guess
any one buy future batch my advise go with 9 pairs batches

You would have to re-do the cables but especially if you don't have a clue what you are doing, I do not recommend it.
Use it for a one miner and buy another psu for the second miner. That is a good option too.

What was the max voltage on this 13.6?
