ANTMINER S7 is available at bitmaintech.com with 4.86TH/s, 0.25J/GH

[fhh]

Batch 2 order from Sept 29th shipped 

[dmwardjr]

So just to verify, wil I be ok with 3 Corsair HX850's to power a single S7?  One PSU per blade with the third also powering the board.  I have these PSU's sitting around after selling off the 3 S5's they were powering.

You would be okay with 2 of those.  Don't need 3.

Make sure you use all 3 PCI-e cords on each blade because the gauge wire for the PCI-e cords provided with the HX850 PSU's are small compared to others that are custom made.  If you had custom made PCI-e cords that are 16 gauge like mine, you would be fine with 2 PCI-e cords for each blade.  That's my opinion.

But I believe they only come with 4 PCI-e connectors each, and I need 9+1 to power it up, right?

I edited my previous post to say if the HX850 does not have enough PCI-e ports, you will need 3 x HX850's.  That was the reason I bought the AX860.  It has 8 x PCI-e ports and it's platinum rated.  I use 240 Volts now for IBM 2880W PSU's that are platinum rated with breakout boards that have 22 x PCI-e ports.

All,

I need a suggestion. I order BITMAIN AntMiner APW3-12-1600 PSU Series with ANTMINER S7 BATCH 3 recently. Order hasn't shipped yet.

I am double minded about PSU; will that work in America?
https://www.bitmaintech.com/productDetail.htm?pid=000201505040743496917U7kGsCm0694

Voltage Range
176-264V AC
 
Starting Voltage
200-205V AC

Would some help me please..

Yes, it works in America.  However, you need access to 208 to 240 Volts instead of 120 Volts.  This would be a 2 poll breaker in the Main Service Panel and a minimum of 20 amps with 12 AWG wiring.  If 2 poll 30 amp breaker, you need 10 AWG wiring.  I don't think you are going higher than 30 Amps if you are installing a 240 volt outlet for the BMT 1600 watt PSU if you are in your home.  I would suspect if you were in a data center, you would not have asked this question.

240 Volts is the way to go.  You can run twice as many rigs than you can with 120 Volts.  If you don't know what you're doing with electricity, get some help locally.

That's right dmwardjr,

I would have not given second thought about power calculation if I would have been purchase Colocation space.

So that mean, I will have to arrange electrician to do that power adjustment if I was to use S7 and APW3-12-1600 PSU at my home?

What if I buy this type of PSU http://www.frys.com/product/6806106?site=sr:SEARCH:MAIN_RSLT_PG   then sure I don't need to do any changes above. Right?

Thanks Again

I would use one with more than 1200 watts.  The S7 is rated at 1210 watts @ 600 MHz.  You would have to under clock it for this PSU.  Also, I would be concerned about the voltage provided by this PSU.  I think you're better off getting an EVGA 1600 Supernova.

After the 90 Day warranty, you might want to over clock your rig.  You would be able to over clock it with the extra wattage provided by the EVGA 1600.

So just to verify, wil I be ok with 3 Corsair HX850's to power a single S7?  One PSU per blade with the third also powering the board.  I have these PSU's sitting around after selling off the 3 S5's they were powering.

Your are absolutely right

I found 1500w PSU here. http://www.frys.com/product/7590536?site=sr:SEARCH:MAIN_RSLT_PG   for S7.

I think one should be enough with 120v wall socket outlet in America. Even overclocking S7 shouldn't be a issue.

[notlist3d]

So all this tells me, that I shouldn't try mining with S7 at my home with APW3-12-1600 PSU.

What if I buy this type of PSU http://www.frys.com/product/6806106?site=sr:SEARCH:MAIN_RSLT_PG  

I think lot of other people are doing same. See here https://www.youtube.com/watch?v=uNbaZwqdPAc

He is using http://www.newegg.com/Product/Product.aspx?Item=N82E16817152044 PSU with S5 Miner.

However, I can't find power consumption for S5 whether it's 120 or 240V

S5 and S7 are really nothing alike on power.  I mean just on ports alone were talking 4 PCIe ports compared to 9 + 1 PCIe ports.     I personally would not pick that raidmax if your talking about powering the S7.

If you don't use all 9 power ports you will void warranty, and 1 for controller.   More and more home and hobby miners I think you will see getting 240.

[Biodom]

Kind reminder:
When mining with S7, be sure that you've connected the internet properly and the internet is working well, otherwise, the boards may get burnt easily

I would not take this seriously. This message is not from Bitmain.
They would have used proper channels, and not post a poorly written post on a forum, with an unknown username, lol!

It is a Bitmain account, Janet's successor as she is off doing other things. I've asked them to add it to the BITMAIN signature.

how can we make sure that "internet is working well"?
"oh, no, your miner boards got burned....you did not make sure that internet worked well".
I understand that he means well, but this is just impractical, seriously.

Yea that is a bit unnerving considering no ISP is 100% guaranteed and even my home router needs to be bounced once in a blue moon.

people are being surprisingly nonchalant about it.
...I woke up at 3am this morning and at first could not figure out why.
then i heard a tiny noise coming from s7 (much less than s5)
;run to it, Internet is down ("internet not working well" situation)
miner is still doing something and fans are on very low, and air is coming out quite hot.
Thankfully, I had a Vornado fan blowing into intake for such situations and to help with cooling, so no critical overheat occurred.
Internet came back within 2-3 min and it was back to hashing.

all i am saying: beware and try to adapt. i can practically guarantee that it WILL happen in large hosting because usually service guarantees just 98% uptime.
If service loses internet, but power is on....

That's my problem.  I can't justify going up to 240, with the uncertainty on the halvening next year, I'm just hoping to break even on this with my lower winter electric rates and we'll see what happens to the price next June/July.  Either efficiency will have to greatly increase, or pool hash will have to drop unless people don't mind losing money mining at higher and higher difficulties.

My only concerns with that PSU is the following:

It says it has 8 x PCI-e ports.  You need 10 x PCI-e ports OR you need at least 2 PCI-e cords provided with the PSU that have splitters.  Which will provide the 2 additional PCI-e cords needed to power all 9 ports on the 3 blades and the 1 port for the controller.  It is hard for me to tell by the photos if at least 2 cords have the splitter [Extension with addition 6 pin PCI-e male connectors] on them.

Ah that's a good idea, I'll put my Vornado right in front of the intake fan to help push air.

I rec evga 1300 G2 with two extra PCIE splits, ordered separately. One can be had used for $125-130 or new/new other for ~160-200 before tax.

I think 3 HX850's would do it.
HX850 has 4 pcie connectors on the modular psu.
Each hashboard on s7 is 400 watts.
One of them can power the controller with the extra pcie
s5 is 300 watts per board.

I found is rather scary when you just reconfigure a running s7 that the fan speed drops so low so quickly.
It should ease off slowly allowing the chips to cool a bit.

After looking at it closer, it may very well have 10 x 6 pin PCI-e connections because of splitters or pig tails on some of the cords.  It says the "value" is "10" on 6 pin PCI-e cords.

I agree.  I'm a minimalist though.     I understand him doing this if he already has these on hand and wants to have minimal up front costs.  If he plans on adding more rigs in the future, it's best to safely gain access to 240 Volts and purchase "used" server grade PSU's with breakout boards.  It's cheaper and able to power more rigs.  Yes, gaining access to 240V dedicated circuits may cost a bit in the beginning.  Especially, if an electrician is paid instead of doing it yourself.  It turns out being cheaper afterwards as more "used" server grade PSU's and PDU's are used to power hardware.  Also able to power twice as much hardware than one could with 120 Volts.

no, i didn't, as i usually wait a few days-this saved my hide a couple of times when upgrades were bad.
upgrade might help, but it seems that it is a problem that migrated from s5 to s7 and if it was easy to fix, they would have done it long time ago.

And I fully agree, 240 is the way to go if I didn't have to pay an electrician to come out and do it...hindsight is 20/20, I wish I had 240 back in 2013 when the ASIC revolution was beginning...heck I wish I would've kept mining back when I was using my gpu in 2011 rather than quitting because $2-3 per btc was a waste of time...even though my low-end gpu was making 2-3 btc a month at that time.  But with uncertainty in 2016, I can't justify the up front costs now to rewire my basement which is finished, so add extra cost there as well.  So recycling my 3 PSU's is great for me.  Who knows, if btc price really starts to climb next year, investing in more power may be worth it...or if I consider co-location and moving miners off-site with server psu's to power them.  But for now, I'm happy pissing off the wife with the even louder S7 than my 3 S5's...

So is that a right choice to buy http://www.frys.com/product/7590536?site=sr:SEARCH:MAIN_RSLT_PG for S7?

I haven't seen S7 personally with my naked eyes, however I am sure 10 x 6 pin PCI-e connections has to do with connectors.

It appears to have ten (10) 6 pin connectors for PCI-e ports.  It also "says" it is 12 + Volts.  As long as it's 12 and not too much less, you will not have to be concerned about hash rate or HW errors.

Thank You dmwardjr,

You made my day. I will wait for my S7 to arrive. If this PSU + S7 works, I will add more hardware in future.

Now, I need to find the way, how much will be daily power consumption.. :-( I have no idea

I am with you on the 240 volts. Switched over so I could run 40 s5 at home. Six 30 amp nema L6-30 plugs.
Safer, wires are cooler. You are not going "up" to 240, it is already there in your house if the wires are run properly.
