Very nice Dogie! Your write ups are hands down the best and a staple to the community. Thanks for taking time out of your day to help us all.

No SeaSonic?  They are the standard.  They actually build their powersupplies unlike every company on the list. :)

I'll get Seasonic added in the next revision then. I was waiting for suggestions rather than assuming what the US market likes to use, EU and US PSU preferences are very different. For instance over here, we don't get PCP&C at all :(

nm .........

jonnyguru reviews help too.                                                                                                                                                                                                                                                         

Very nice!!

Can you add how many PCIExpress cables also.Been having a helluva time finding 500+ watt PSU's with at least 2 separate PCIE cables (not connectors) for my Ants  ::)

Decided on the Corsair CX600,I'll verify if it indeed has 2 seperate cables  ;)

I know for sure,cause I have these, Corsair CX750M has 2 cables with 1-6pin & 1-6+2 on each.Can power one Ant.

Corsair RM850M has only 3 (not 4) PCIE cables with 1-6pin & 1-6+2 on each,so can only power 1 1/2 Ants  ::) Won't be getting this again  :(

A PSU I didn't think I'd like,but ended up I do like,is the Ultra X4 850 watt modular (60 amp,single rail too ;D ),it has up to 6 separate PCIE cables with 1-6pin or 1-6+2 on each separate cable  :o  
But with only 850 watts it's good for 2 Ants  ;D

It's from WAY back when,but still up to date for specs:
http://www.tweaknews.net/reviews/ultra_x4_850_watt_power_supply/

http://www.ultraproducts.com/applications/campaigns/campaigntemplate.asp?CampaignID=1111

http://www.tigerdirect.com/applications/searchtools/item-details.asp?EdpNo=4558892

Thanks Dogie!!!  ;)

You can work that out from the fact that no manufacturer will put more than 2 PCI-E express connectors on the same cabling. You'd have to go down to ~AWG14 or less to carry 450W on one cable strand. I'll add it to the list.

True,but its confusing when newegg says "2 6pin" or "2 6+2pin" connectors & the pics don't help cause their blurry or the cables are jumbled up  ::)

Quoted. Can you delete the table out of yours, otherwise it won't 'update' as the rest of the OP is changed. I'll delete it out of mine once it stops being useful.

Just got the Newegg e-mail.  The HX 1050W is currently on sale (http://www.newegg.com/Product/Product.aspx?Item=N82E16817139034) for $179.99 AR/AC using EMCPHHE25.

This is a great thread and quite necessary.  I even thought about doing one up myself but because I'm so new I figured people might think I have some agenda or something.


This.  Big this.  Especially for people who want to later re-task the power supply for something else.

I'm only in the US market so all my info will be slanted towards that.  Specially slanted towards a ratio of performance and efficiency:value.  Warranty also important factor as well.  I also don't hesitate to buy products on rebate or refurbished hardware from well known suppliers so I'll throw that into the mix as well.  The prices I've listed are the "deal" prices; not necessarily the everyday prices.

Also I think some sort of number-letter coding for which mining hardware each supply is confirmed to work with would be very helpful.  Especially for n00bz.  ;D  Like maybe 3B if it can run 3 Blades or 2C if it can run 2 Cubes for example.

Do you want to list hardware confirmed to have issues of sorts?  For example, I listed the SS-760XP2 but at stock it will not keep Cubes powered on, even just a single.  Likely a no-load/overload shutdown protection of some sort that could be solved with a capacitor (https://bitcointalk.org/index.php?topic=352658.msg4044394#msg4044394) but I haven't that yet tested.


The table has been re-added. 

The information I had added was removed from dogie's "quote" less 24 hours after I originally posted it, which is apparently when it stopped "being useful".

I have since and will continue to update the pricing post above on a regular basis.  Much more regularly the OP has been updated since the inception on this thread.

If/when that changes, I may stop adding this data to this reference thread.  I've offered to collaborate to help dogie's OP contain more data in his format, but he seems disinterested in that possibility (read the thread for more info), so I've moved on and started to maintain and update this data myself for the reader's benefit.

And your second one :P

Not understanding the issue.  But okay, also done!

Is there some sort of SMF glitch with multiple tables?  

I figured I'd do it that way to make it easy for you to copy/paste the code straight into your table should you want to.

Its because when this thread is 9 months old, and the OP has been updated again and again, our random posts in the thread [especially 1st page] will remain old and out of date. I have the code recorded, thanks.

Okay.  I suppose that makes some sense.  

But that's true of all threads.  If I go read a major Pool thread, I'm going to find outdated posts.  Especially on the first page.

The specs of the powers supplies aren't going to change.  Prices will.  To me in a thread like this that "snapshot" data might actually be useful.  Like, 9 months ago this power supply was $175.  Now in the OP it's $100.

Your ratings will change too of course based on the pricing.  I don't think you have plans to update those on a very regular basis.  Maybe a high/low/average pricing would be a better approach.

For me personally I factor in cyclical pricing on technological purchases when making hardware choices.  Especially since sales are typically very cyclical.

Thanks SO MUCH for this post!! I think it really stands out next to your great setup guides. I'd like to caution others before recommending other power supplies be added to the list. A 'great' power supply in any other application doesn't make a great ASIC miner power supply. If it hasn't been tested stable for a few months on a Cube, Blade, Ant.. etc; please don't recommend it. I have gone through 2 other 'quality' power supplies that would do wonders in a PC, that have failed miserably within days at powering a single Cube. A 600w OCZ and a Cooler Master V1000 (1000w) both were not up to the task.
I just ordered 2 CXM750's to quench my thirst for power. Hope to have my Cubes up and rocking in a few days!!

If there was a tutorial section, I think you could fill it up alone.

And, as one of those taking up your time with PM's and you answering me in a very timely manner...
Thanks again!

It will be updated pretty often (likely weekly), but sites like Amazon can change every 5 minutes if they're price matching competitors.

Thanks for your kind words :) Thats the problem with ASIC PSUs, providing 12-100A 24/7 is totally different than spike 12-100A. It takes a different beast to power an Antminer/cube.

Yeah. Weekly at least here in the US can mean a wide variety of prices.  

That's why a high/low/average might be more meaningful.  Depends who the intended audience is I suppose?

I don't think that was directed specifically at me but in case it was by any chance all the power supplies I posted are confirmed to work with mining hardware.

The exception being the Seasonic SS-760XP2 which did NOT work with Cubes.  Even just a single, which was surprising but as I mentioned it's likely due to a protection issue rather than a lack of power issue.  The SS-760XP2 is a beast of a PC level supply.

Dogie, why did you not like the EVGA 1000W PSU? I ran 2 cubes and a BFL 60 single for 2 months on that thing and it was awesome. 2nd favorite is the Corsair AX 1200. Nice guide. Thanks!

I don't think it's a question of "not liking" it.  It's a quality power supply.

It's the fact that the algorithm is taking price and perhaps other variables into account when computing the "dogie score".

My guess would be that the algorithm also weights all scores relative to one model.  That one being the Corsair TX750M currently.

Its not relative, certain PSUs can go >100 if they're excellent and excellent value. Its rare that the much larger PSUs score well as their relative performance per $ per watt is low. Its almost always cheaper and more efficient and flexible to get two 2x ~750s.

Very nice doggie!!! Great job!!!  ;)

 :D  Of course it's relative.   It might not be calculated that way, or intentional, or even intended bias.  But the TX750M scoring exactly a 1.0 relativity is what we call "not very statistically likely".  If it's a happy accident, I'm a monkey's uncle.

A human built the algorithm.  It's not infallible.   You have some obvious bias for Corsair.  There's nothing wrong their power supplies.  I own a ton of them.  They're great.  But there are equally decent and in some cases far better choices - especially economically speaking. Magically, they've been excluded from the list so far.  Unfortunately, the way the info is being presented, beginners might make the mistake of putting real stock in the "dogie score" and think it's a scalar difference between choices.  

FYI - some of your Corsair links are incorrect.  They simply lead to the wrong product.  I would have posted an update with correct links in a table as I did before but that wasn't very well received, so I'm erring on the side of caution this time around.

Lastly, I'll ask this again - who is the intended audience for this thread?  EU?  US?  Both?

Because the prices that are included with the Seasonic update are grossly incorrect for even the average price at major retailers like Newegg.  I'd recommend Hover Hound if you're not already using it.   Cases in point: Seasonic Platinum 760W was $100 (recently), is currently $169.99 currently, and is listed on this list as $199.99.  What's worse?  YOU SHOULDN'T BUY A SS-760XP2 TO USE WITH MINING HARDWARE.  Didn't someone already post in this thread to confirm at stock it WILL NOT WORK with mining hardware?  Oh right.  That was me!  :P

Back to pricing.  Since price is an inherent part of the algorithm, having inaccurate prices skews the data quite a bit.    Which is why I said perhaps a weighted average price or a high/low/average approach might be better.  I understand Amazon is usually a good common denominator for comparison shopping for a lot of things, but PC components are sometimes ridiculously overpriced there.

This is a good start towards a list, a very necessary thread here which I've glad you're working on, and a lot of the foundational work is there.  But it needs refinement.  I'd be happy to help, but last time I tried it wasn't all that well received.

It didn't make sense to link to hardware from all one vendor and at higher prices... until now.  I finally put two and two together.

OP contains Amazon referral links.

Didn't dawn on me at first to even check.  I believe in full disclosure so I am posting this information here.  

Also editing my posts in this thread back to their original info.  Because I'm actually here to help others without any promise of profit.

well, it's kinda expected when someone's using url shortener.

i realized it since the first post.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         

I wondered why he didn't just use Newegg  ::)

Not really.  From a readability and maintenance stand-point it would make sense to use it too.

Not to mention that most shorteners give clickthrough statistics which could be useful to see which supplies were more popular or at least getting more traffic.

I don't even have an issue with even using referral links. 

But it was done with no disclosure in a very clandestine manner.  And then to ask another user to REMOVE information from the thread because of the following bogus reason -


instead of the real reason - can't get income if someone buys one of those!

dogie also stated


it was deleted within 12 hours.  none of that info was added to the OP.  I guess it stopped being "useful" already?   ::)

1.001095833 if you really must know. And that's with a hell of a lot of scaling to get a range appropriate for humans to interpret.


Corsair make the best PSUs with the best attributes for mining, at reasonable prices. The unbiased MATHS backs that up in some cases, why is that unexpected? The CXM range is already the best seller by FAR.

US at this second.


Be patient, the guide went up three days ago and I've been in surgery for one one those, and not wanting to type much afterwards. Other sites will be added, but its very likely the 'cheapest' will change almost daily as they price match/stock price adjust all the time. Amazon links at least provide a 'here it is on the market, somewhere'. Its not easy to create dynamic code with static forum code, but it will get better.

Maybe because, as I said in my other post just now, its been up THREE days and I've been in surgery for one. More sites will be added soon, give me time. Yes, links have affiliate IDs in. I used to disclaimer them all the time, but it turned out no one actually cared. It helps contribute to what is otherwise a free resource, like google. And no, it doesn't even cover a tiny portion of time time.

The original reason still stands, I'm going to come back every week and update the OP, I highly doubt you are going to come back in 6 months and change your then grossly misrepresented links when they are out of date.


Newegg is being added too, experimenting with whether to add both or the cheapest of that weak. Again, time. Be patient.

It was added to the OP where useful, I have your code saved. But as exactly I was saying, the 'amazing deal' link you posted was $40 more expensive within 12 hours.

Best is a subjective term.  The MATHS (maths? really?  ::)) also show better deals are out there with equally performing or even better hardware.

A $10 server-grade 90+ efficiency Z750P with a $40 board from sidehack will likely be the "best" at the moment.  I think the MATHS ( ::)) would show it beats out all Corsair models, even at their best sale prices.

It's not even on the list.


Then your pricing is extremely inaccurate.  I know.  I buy $1,000s of hardware per month.


I don't want you to doubt my appreciation.   I don't need this information but others do.  I thank you for that.

I don't doubt you have personal issues that may restrict your ability to keep this information organized or updated.  I offered to help.  Not only did you decline it, you removed the information for no other reason that it would conflict with you receiving a referral sale.

So I suppose what I do question is the manner in which this is being done at the moment.

Hey, thanks for the vote of confidence in a new member who is TRYING to help others.  We're you ever here on this forum doing that? I imagine you were.  How would it have felt if a member here said that to you?


Again why I stated your pricing model is just not a good one.  A single point pricing model gives no indication of what might be available.  It just give single data point at whatever time you happened to update it.  Single point of data = single point of failure.  Can't see any kind of trending from ONE data point.  I don't care what kind of MATHS you use.

A weighted average or a high/low/average pricing model would give a far better indication.

Didn't mean to skip over this post.  Yeah Newegg should definitely be included.

Not in reply to Unacceptable specifically (I'm guessing he/she knows about it), but for anyone else reading this, if you're not using a price comparison extension of some kind, find one and use it.  

I recommend Hover Hound to get you started.  It's available for both Firefox and Chrome and gives real-time pricing comparison and pricing history over time from a number of different retailers.

A search for a specific piece of hardware over at Slickdeals.net is also useful for gathering pricing over time.

Updated the table (https://bitcointalk.org/index.php?topic=486121.msg5357323#msg5357323) with meaningful High/Low/Average pricing data.

Added a Key and adjusted the formatting to increase readability.

If anyone has any additional suggestions on power supplies to be added to the list that they've tested and confirmed, please feel free to post them here or PM them.  I can add them to the table I created.  I have a very good pulse on pricing data and I'll be updating that far more regularly than the OP likely will with more meaningful pricing data than the OP captures at the moment.

From that post it should be easy for dogie to add any data there into his main table in whatever manner he sees fit if/when he can.

Most of the incorrect Corsair links have been corrected.  Thank you.

The TX850 above however is stll incorrectly linked to the TX850M.

Also, again since it's still in the list, I highly recommend removing the SS-760XP2.  Or at least adding a caveat.

I have the supply, in fact it's running the machine I am typing this out on, but it DOES NOT WORK with Cubes.  

Hi Dogie, you might want to consider reviewing beQuiet PSU's.
They're pretty populair (at least in EU), availability is good, price/quality is good and they have a big assortment PSU's (80plus bronze/silver/gold/plat in a wide range of wattage)

Laptop crashed while typing a reply on every point so going to tldr. Let me know if anything needs clarification.

The list isn't exhaustive, things will keep being added to it. The dell one will go on the list when I work out how I want to format two links being required. Also you can't get them from a reliable source, new, for $10.

I was referring to links that don't get updated, they become misinformed and misrepresentations. For example if links are posted outside of the OP, in 4 months they STILL read "x power supply for $y", even though that psu could be 5x more, 5x less, not sold at that site, at all or recalled due to being dangerous. The OP will be updated so doesn't suffer from that problem.

Spot pricing is required as that's what people buy at. Average pricing just guarantees that the price is going to be wrong at every point a purchase is made. It will be closeish, but it will be wrong. A spot price is guaranteed to be right, potentially for the whole period before another update is done. Again, people buy from spot prices not trend data.

Will update the link when home.

Still working on a way to confirm cube compatibility. Its a niche product, and all of these PSUs will work for the other 95% of ASIC hardware. I don't think it would be appropriate to kill a PSU off the list entirely due to overload protection. That should be an additional feature/criteria, not a requirement.

Do remember that each additional piece of variable data you add, increases the time taken to update the list. Ie we only have about 40 PSUs at the moment. If that ends up at 100, thats 2.5x as long.

Then if you add average and hi low pricing, as well as 2 store links, thats a further 5x information that requires updating. There becomes a point where its not viable to run with so much variable data because people will buy or not regardless of $5 variations of what we've listed the price at.

That's an assumption you've made.  That my post won't be updated.

So far, it is.  Let's keep the assumptions to a minimum.

At this point it's more updated than the OP is.  The CX430 is on sale for half what you have listed in the OP.

That's a 67% difference if I am doing the MATHS right.


By your own admission, Amazon pricing can be very volatile.

Case in point?  Of the 67 supplies listed in the OP as of this moment, 37 of the prices are incorrect.  Some are grossly incorrect.

What's more is it's tapping into a single source of data for pricing.  

So... guaranteed to be right?  Guaranteed?  No.  I'll disagree there.  Sorry.  You can't have it both ways.  You can't say spot pricing is guaranteed and then say Amazon is too volatile for you to keep up to date accurate pricing information.

Educated buyers - which I hope we all are or hope to become - shop for things before buying.  

They compare prices.

They want to know how things were priced recently.  Am I getting a good deal here?  Oh, the average is $40, and the low was $25.  So at $30 I'm in the "Good Buy" range.  At worst, your OP should link to CamelCamelCamel so that people could see that data for themselves, even if you won't provide it outright.

What's worse is you ARE BASING YOUR SCORE off this incorrect data.  And then people are making decisions from that.


You're working harder.  Not smarter.  And we're talking significant differences between the prices you're linking to and what the average street price AND sales price is.

I've already started throwing some of this data into spreadsheet that spits back forum bb code in one copy/paste.  It has the ability to capture multiple pricing points and create some metrics off that.

A db aggregating more data would be the next logical stop.

Guaranteed to be right at one point in time.

You're taking this all way, way, way too seriously.

Its not about calculating average prices lol, its about updating 6 different values and 2+ links in the table, per line, per update cycle. its not viable.

It's about prices which are one of the fundamental factors in computing a "score" that a lot of users - especially those who don't know - will view as not only a scalar value but as an ACCURATE scalar value.

If the price of a model changes by a significant value, it doesn't affect your computed score?

I'm beginning to think you don't quite understand here.   :'(

Your doing a fantastic job Dogie!!!

Just an average price should be good,we still have to go to our favorite retailer to see if it's in stock or on sale anyhow  ::) 

My fav is Newegg,they ship faster & have free shipping more often & IF I have to return (within 30 days for any reason) I call em & have them look at my $50,000+ purchase history over the last 12 years & they email me a free return label,heck I even get items shipped BEFORE I return the defective item......sometimes  :D

I used to build high end gamer PC's & ship all over the US & Alaska even :)  Since PC gameing is in a dive,not so much anymore  :(

Amazon is ok,but that "return" feature I enjoy with Newegg is not there,in most cases for me at least  :(

Still would like to see the amount of PCIE cables per PSU,but I understand that that info is difficult to find,believe me,it took awhile for ME to find it  :D

Yeah.  That's exactly my point.

Average Price != Spot Price

Average Price = Average Price


Same.

For those who don't purchase quite so much, or hell even if you do like myself and Unacceptable, get a ShopRunner account.

It's free if you have most types of American Express cards.  Free 2nd Day Air shipping and free returns.

I don't do "credit" cards nor do I have a bank account  :D  I pay now.........& don't give a crap to get with the "credit/debt" mindset !!!!!!

My Paypal is all I have to purchase with or cash or BTC!!!!!   ;D  I don't even want to do bank wires  :P

I'm in "revolt" mode & will not get be using any banks for as long as I can help it  :P  At least here in the US  ;D

AA > CC. Free money for.... well... spending money. Get one if you can get the credit then use it whenever you possibly can.

p.s. I'll sort the pricing out this weekend, Friday night is currently booked up with other work.

You're missing out financially then, my friend.   I don't carry any balances (no interest charges incurred) and gets $1,000;s of credit card rewards each year.

Not to mention there are constant offers in my mailbox for cards with interest free periods on purchases.  Meaning I can make purchases, invest the cost of the purchases during the interest free period, get the cash or program rewards for those purchases, get the interest earned by investing the purchases' cost, and pay the bill in full at the end of the interest free period.

Exactly.  Free money for basically nothing.

Updated pricing (https://bitcointalk.org/index.php?topic=486121.msg5357323#msg5357323).

Pretty decent price drop on the RM550.  

Listed in the OP as $113.07.  On sale at Newegg for $69.99 AR.  Amazon for $79.99 AR.

Not a super great deal, but very decent.

Also a price drop on the CX600.  $37 AR isn't the lowest price it's been, but it's close.  Listed in OP as $66.24.

$19.99 AR CX430 has more value per dollar at the moment, but all three are smaller supplies that may not fit the needs of many.

Got my CX600,I can confirm it has 2 separate PCIE cables with 1 6+2pin PCIE connector on each!!!  ;D

Perfect for 1 Antminer  8)

From Newegg $69 free ship ATM,but the free ship is 4-7 day via DHL  :'(  So I opted for 3 day UPS at $5.99  ::)   Total= $76  ;)

http://www.newegg.com/Product/Product.aspx?Item=N82E16817139028

Actually it's $37 AR and the $12 coupon (EMCPHHB25) as listed in the post above yours and linked in this post (https://bitcointalk.org/index.php?topic=486121.msg5357323#msg5357323) since yesterday.

Also, even if you don't go the credit route, you can get a free trial of ShopRunner and usually get it extended almost indefinitely.

ShopRunner = Free 2-day Air shipping from Newegg

Updated pricing (https://bitcointalk.org/index.php?topic=486121.msg5357323#msg5357323).

Added pricing for CX500.  Listed in OP as $49.99.  Actual price via OP link is currently $57.74.

Currently the CX500 is available for $29.99 AR.

Probably one of the most cost effective supplies available at the moment now that the $19.99 AR 430W deal is over.

Deal for the CX600 is still on-going.  $12 off promo ends 3/6.

Will that CX500 power one OC'ed Antminer?

It probably can with some creative wiring but I wouldn't recommend doing so. 

You should be looking at supplies with multiple +12V rails.

Updated the pricing post (https://bitcointalk.org/index.php?topic=486121.msg5357323#msg5357323).

Have been busy with work and life this past 12 days since my last post in this thread.  But since my pricing post has L/AVG/H pricing all the pricing is still pretty much very up to date.  Funny how that works that way.  ;D

Two changes though -

I added a new link to the Z750P option and updated that pricing.  You can get $10 or less Z750P supplies if you know where to hunt, or you can get an entire kit from sidehack that has the supply, board, and cables for $70 which is pretty competitively priced.  So all that was added to the updated pricing post.  I've purchased server interface boards and cables from sidehack.  Trustworthy guy, and he and his minions as he calls them do good work.

Added the CX500M and CX600M to the pricing table.  

OP has CX500M listed as $54.99, actual price via OP is $60.92, but the CX500M  is currently available for $34.99 AR (http://goo.gl/320tcE).  

OP has CX600M listed as $64.99, actual price via OP is $71.73, but the CX600M is currently available for $44.99 AR (http://goo.gl/aVTy3x).  

If modularity is important it may be worth the premium above the regular CX series sale prices.  Otherwise for purely mining hardware powering purposes, there are more cost effective options.

Since the OP hasn't been updated in a while, I had some spare time and recoded my backend that parses out forum bb code, restructured my pricing table a bit, removed useless portions of my own post that were there, and added more relevant and useful data for the user.

Updated the pricing post (https://bitcointalk.org/index.php?topic=486121.msg5357323#msg5357323).

Now there are several vendors listed: Newegg, TigerDirect, Amazon, Frys, and an "Other" field to accommodate special deal opportunities.

For now that portion of the table will show only the better deals that are currently available.  I may eventually opt to have direct links to all the vendors for all supplies and just bold or single out the most cost effective one, but for readability I'm keeping it simple for starters.

The L/AVG/H pricing data gets updated for all each update iteration so it will keep current with the cumulative running pricing long term, whereas the right most portion of the table will single out "good deal" opportunities at the moment.

But maybe there are better ideas out there.  Feedback and/or collaboration is welcomed!

New current deal opportunities:

• CX 430W @ TD for $20 AR [Listed in OP: $40; Actual Price using OP link: $50]
• SeaSonic G 750W @ NE for $80 AR [Listed in OP: $112; Actual Price using OP link: $130]
• XFX PRO750W @ AM for $75 AR

I didn't see the Thermaltake in your pricing. Thoughts on this?

Toughpower XT Platinum 1275W Snow Edition

It wouldn't do well, it only has 65A for PCI-E devices due to its split rail design. Thats 780W on a 1250W PSU.

Thank you for your thoroughness and prompt response. I'm new to the mining rig game, but use to build PC's back in the day. It seems like your PSU ratings anything over 850 is on the average to poor side. I may have missed this in the thread, but is it more efficient to stack lower wattage PSU's than get a big one? I'm building a rig, but it will be pieced together (only 2 GPU's to start, R290 or 290X), and rather than continuously upgrading/swapping out PSU's, I was wondering what best PSU's would be paired. going to build it in a rectangle 19x13x10 milk crate.

Essentially the larger PSUs can't compete on price efficiency compared to the mid range sizes (~600-800W). Pick yourself up something corsair, can never go wrong. And yes, much more efficient to bridge 2 mid PSUs than one monster.

TXM or CXM 750? pretty close on spec, but the more expensive one (not by much) has a 5 yr warranty instead of 3.

CXM I usually go for.

Thanks I got two CXM 750's. What is the best dual PSU adapter to get them running in sync? My motherboard is the ASRock H81 pro BTC

Easy peasy. (http://goo.gl/VL3Kog)

you rock, thank you! I'll be building the rig this weekend :)

So I'm currently on the fence between the cx750/cx750m, the dell Z750P+gekko science board, and a IBM Blade Servers (DPS2000) ($40 off ebay).

I'm currently running two antminer s1's (dual blade) connected to one cx750m. Everything appears to be running smoothly, any critique's on this setup?

I will be buying a lot of antminer s1's over the next couple of weeks, The psu's I buy from here on out I'd like to be scalable, which from what I understand could be any of the three power supplies I've mentioned above. Suggestions?

Eventually I will be swapping all the antminer's for monarch's, but that will be farther down the road, however I would prefer to not have to buy new psu's. Obviously we don't have power specs on the monarch's yet, but from a rack power and organization standpoint, if you are going big which of the three psu's above would scale the best?

I noticed no one has mentioned redundant power supplies, why not?

I also noticed no one has mentioned UPS's, what are you guys using for that?

Are there any advantages to running psu's in sync when they are outside a computer?

In relation to house circuit power, as long as I'm not blowing any circuit breakers, I shouldn't have to worry about if I'm on a 15A or 20A or 30A circuit right? I only should have to start looking at that when circuit breakers start tripping? Or in other words, if I need more power I should just run another 15A circuit right, not try and increase the 15A to 20A or something?

Someone said somewhere about keeping your circuit power utilization under 80%, is that really necessary and if so any suggestions on metering devices?

No problem

750s are too close for 2x S1s overclocked in the long term as you'll be running them at ~825 24/7. If you want a solution for super long term, get 1200AX (http://goo.gl/RA5lzM)'s. They are expensive, but you can load them at 1300 24/7 (3 S1s OCed) and they have a ridiculous 7 year warranty.

Redundant power supplies cost twice and much, and its not mission critical. If a PSU fails, you unplug it and plug another one in. Nothing lost. Same with UPS, it costs so much to have even 10 minutes of backup power for a mining operation, but the cost of 10 minutes of interruption is virtually nothing.

No reason to sync PSUs unless they're bridged (powering the same hardware).

If the circuit is rated to run that current, it will run that current. You can run as many circuits as you like as long as none of them exceed the spec of the wiring, the circuit and the overall system. Consult a qualified electrician.

PSU efficiency is highest at around 90% but the difference is minimal.

does all PSUs need to be paperclip empowered?

edit: and i dont get, i have a seasonic 750 80plus gold: why this PSU is so low rated in your analysis ???

Its all a relative scale, so 60 doesn't necessarily mean its a bad power supply, but that there are potentially other better buys out there.

have been reading for hours. i'm turning it over to you experts!

recommendations, please. best overall power supply for an S1 Dual Blade AntMiner.... not overclocked. In a four months I'd like to overclock with the same power supplies. need to power three dual blade machines.

amazing resource here, thanks all and thanks Dogie!

axi1200 (http://goo.gl/RA5lzM)

Damn! I got a reply from Dogie!? Thank you, sir.

So buy a single power supply and run all three. Reading about the on the fly power adjustments to save juice? Great stuff.

In my head I was hoping to pay ~$65 (+shipping) per power supply and pickup three. Read a post that had different tiers (build/components/quality) and I'd decided I don't need top top tier. I'd like to find the tier two solution at the tier three price. Can proper power be had for three S1's in the $250-275 range?

Someone once said that if you buy the best you won't be disappointed. Unfortunately money is an object.

Again thanks very much. Any additional recommendations / explanations are welcomed.

If I want to overclock the miners in the future, will the AX1200i have enough juice? Further consideration, is this really a good recommendation to power 3x S1 dual blade 180GH/s S1's now (~360W per) and then overclocked (~400W per)?

The longer you run a racecar in the red the sooner it is going to blow up. Hmmm.

again, thank you.

EDIT: I now see 1320W peak power on the 1200. So... why am I doubting Dogie?!

If you've got a less expensive solution I'm all ears.

AXI's are the bees knees and last forever, and will easily do 1300W 24/7. I personally run lots of CXMs (http://goo.gl/BSzTte).

where to buy new S1 miners?  in the US, who do you recommend? who should I avoid?

jones gear?

i think one CXM per at 500W will do. yes? thanks again!

i would not, ever, EVER... buy or attempt to buy any bitcoin mining gear on ebay.

JG?
112bit?

Do you find that the 1200AXs are that much worse then the AXIs?  You can generally get the axs for like $50 cheaper,  and the axi's only seem to add the fancy electronic monitoring stuff.

the 1200 watt cosair is  the same as the 1200 watt sea sonic


http://www.amazon.com/SeaSonic-ATX12V-Platinum-PLATINUM-1200-SS-1200XP3/dp/B00JG5LSN8/ref=sr_1_1?ie=UTF8&qid=1401677299&sr=8-1&keywords=seasonic+1200

cost = 290


http://www.amazon.com/Corsair-Professional-Digital-Modular-Platinum/dp/B008Q7HUR0/ref=sr_1_1?ie=UTF8&qid=1401677342&sr=8-1&keywords=corsair+1200

cost = 325

but frankly the 1300 watt evga is pretty solid and far cheaper then the two above

http://www.amazon.com/EVGA-SuperNOVA-1300G2-ATX12V-120-G2-1300-XR/dp/B00COIZTZM/ref=sr_1_1?ie=UTF8&qid=1401677449&sr=8-1&keywords=evga+1300

cost = 195

these are all amazon prices no referral links .  the corsair and the sea sonic are better quality the the evga but a lot more up front.

I own a few evga 1300 and 1 sea sonic 1200   .  I do not own a corsair 1200

Does anyone have the Corsair 1500w:

AX1500i Digital ATX Power Supply — 1500 Watt Fully-Modular PSU

1500 Watts of continuous power, an incredible 94% efficiency rating, and Corsair Link desktop monitoring control make the incredible AX1500i the best enthusiast PC power supply you can own.

$449.99 USD

Do you think that I could run 4 Antminer S-1's? or should should I just run 3 on the Corsair AX1200i Digital ATX Power Supply — 1200 Watt Fully-Modular PSU.

Is anyone running  3 Antminer s1's on the Corsair AX1200i Digital ATX Power Supply — 1200 Watt?

3 on the 1200 is common and fine.

i dont know if it is right to ask this question here or not but hope you guys put me in right direction!!!

i have a LEPA 1000W PSU and would like to connect all of my mining hardware with it (as below list)

1 x wifi router
3 x Raspberry Pi Boards
1 x Gridseed Dual Miner
1 x Rock miner
1 x 20 ports USB hub
1 x 10 port usb hub

i know 1000W PSU will be more than enough to fulfill electricity needs for all above however i wanted to ask you what connectors should i use to connect all of above devices with the PSU and from where i can buy them.

i found one(see below) connector which fulfills power needs of gridseed and wifi router.

thanks for any suggestion and advise

Hi guys,

before I blow up my psu I'll better try to get some advise from the pros.

I want to get rid of some cables and short the (modular) psu at the plug side for kickstart. Can someone help and tell me which ones to short on my evga?

Same these

https://i.imgur.com/yJOvoyg.jpg https://i.imgur.com/VHap4ge.jpg

My EVGA. Which pins to short?

https://i.imgur.com/ItKaM7T.jpg

Thanks in advance!!

Don't short it on the PSU itself, they're not the same pin outputs and many pins are bridged. Bad things may happen.

PCI-E to 2.1mm adapter for the gridseeds
PCI-E to 2.5mm adapter for the rockminer.
USB cable to Pis

I wouldn't power anything else off the PSU, you're better off getting their mains adaptors.

thanks bro, this what i thought that main adaptors will be good but i have only 2 main power sockets and on spare PSU so thought worth to give it a try.

Will cost you much less to just get a gangway or whatever they're called :P

Hello there!!!!!

posted another problem here related to Ant S1 and 1000W PSU; hope you'll advise

Who's Who In Power Supplies, 2014: Brands Vs. Manufacturers
http://www.tomshardware.com/reviews/power-supply-psu-brands,3762-4.html

Do you recommend nox 850w psu?  They are cheap

Cheap and and recommend don't really fit in the same sentence. Miners run PSUs far surpassing what the manufacturers ever intended.

So please guys what psu do you recommend me. I don't know what to do. 1 psu for each s3 or 1 psu for 2 s3? ? Thx

1x AX 1200i (http://goo.gl/RA5lzM) or 2x CXM 750  (http://goo.gl/BSzTte)

Dogie i see you gave best score to:

Corsair CX750M ( i have 2 of this psu, 1 for each S3).

And 2 more S3 coming, so i thought i could buy a Corsair RM850M, i see you gave it also a very good score, so i can run 2 S3 with this PSu, right??

thanks!

edit: sorry you just posted. so you say its better 1x AX 1200i instead of 1x CorsairRM850M? Why 1200W for 2 S3??(2 s3 even 3with OC im getting 725W together). So with corsair RM850M enough, right?? or not??  ;D

that 1200 corsair its so expensive for just running 2 S3, or can i run 3 s3 with that psu?

You can run 3 on the AXi, yes. And just about 2 on the 750, but it gets very close.

but its safe to run 2 S3 with 1 CX750M? I get 725W with 2 S3

Yes

oh ok. i read in other topic someone saying that if you get 725W for example with 2 S3, its so risky to just use a 750W because PSU´s always have a little less than the total 750W they say they have, and better to have a little more extra W than just "20W" more

Its the other way around on most corsair series. They have a peak which is 10% above rated, the rating being 24/7 stable.

oh ok then, you mean that peak of 850W for CX750M? But i suppose they dont have all the time those 850W, just from time to time or whatever. ok then i will try to run 2 S3 with just 1 CX750M lets see if it doesnt explode ;D

Hope some of you can guide me on the above.

It would only have taken 1 or two of the conductors to have broken for the load capacity to have gone way down, and so temperatures way up.

any way of using the eps8 pin  and atx 4pin cables on a psu to power an s3? have a 1500watt silverstone strider.

Not that easy as they don't have screw terminals. You could use an interface board like the blackarrow power distribution board. So EPS 8 pin -> extender cut up -> distribution board -> PCI-E cable cut up -> S3. I don't know what the current limit on those things is.

What do you think about buying for example two corsair cxm 750W instead of buying one with 1200W? Disadvantages?

Fine as long as you dont cross load.

or if you could know which cables are which, just cut off the 8pin and 4pin atx and connect 6 pin pcie directly at the wire with crimps?

Thankful for this forum!

You have 6x S1 miners. You have 3x CX750m and 2x TW750M.  how would you set that up and power the miners?

TW750M?

My bad, not a tw it is an HX750W

So... to run 6x miners with:

3x CX750M
2x HX750W

??

6 S1s = 12 blades,

3 on each PSU, ~620W load, only 4 PSUs required.

Personally, I'm shocked at your rating of the EVGA 1000W PSU.  I also noticed that you didn't differentiate between the G2 and the P2.

I run a 1000W P2 (http://www.newegg.com/Product/Product.aspx?Item=N82E16817438013) myself.  It actually has a 0db noise level at most loads, thanks to the eco switch on the back of it that only runs the fan when it's needed.  Sure, the cost is higher than some others, but it's a lower rating than I'd expect.  Also, the price of the 1300W has gone down a lot recently, and EVGA just released a 1200W P2.

The 10-year warranty doesn't seem to factor in to your calculations either.

Yes it does. The larger units simply don't compete in the rating due to their $/W.

I'm not saying it needs to have the highest rating, but I'm just saying it's a off.  
For example, you rate the Corsair RM 1000W a 77.7.  This unit has nearly identical specs to the 1000W EVGA, except it's less efficient, and has half the warranty.  In light of this, I think the EVGA 1000W needs to be at least a 78.  I imagine that this rating was done when the EVGA 100W was closer to the $300 range and never recalculated.

You should also differentiate between EVGA's gold and platinum series in your ratings.

No it actually has a lower rating because its 1000W is a strict 1000W rating. Corsair's 1000W rating is 1000W 24/7, and is really 1100W by the same modicum. Both were snapshotted at the same ~$200 price.

very important!!

anybody got a couple paperclips i can borrow?!?! shocking the amount of junk i have, yet not a single paper clip to be found. very anxious to get 3 more online tonight and 3 more tomorrow. the current machines i'm very pleased with, hashing away like hippies in a drum circle.

Hi, great guide. Takes care of digging up how many pcie connectors a psu has.
Could you add Corsair HX1000w I just bought one on ebay and don't know anything about it.
Thanks

Scanned the thread for suggestions and couldn't find the corsair cs series mentioned.

Semi modular

Added CS, just waiting on Theymos to inject me some additional posts as I'm at the character cap.

Sweet
What r your thoughts on the 750 and cs850

Doesn't seem to be a justification for the price premium over the CXMs. Yes its a higher efficiency but that's about it.

Glad I can't see the Seasonic 1200W Platinum on there.

I have 2 and they are expensive, but the cables are cheapo.

Firstly, they are 18 gauge ribbon cables, which I was surprised to find, after having good 16 gauge cables on my 2 older ~$100 cheaper OCZ 1250Ws
Secondly, the plastic cable to PSU connectors on the cables/PSU are difficult to plug together properly.

I couldn't get any of the Seasonic 1000s when I needed the 2, so I got the 1200s :(
No idea if the 1000s have these same issues.

I would say 18AWG is pretty standard over most PSUs, but yes @ 1200W that's a bit unusual.

I've got a noobish question to ask a product warning to share.

If I am using a 750w PSU for an S1 that is only using 360w am I still paying the the remaining power? As in, am I still paying for 750w even if I am currently only 360w to mine?

Beware of the Sentey brand of PSUs. The prices are indeed too good to be true. This one in particular keep losing power and within a day caught on fire. I will always read the low ratings first before buying something from now on.

No, the PSU has a 750W capacity, but will only use 360W + a bit for inefficiencies.

OK, thank you for the information.
