I have 2 of these psu-s running 4 S3 overclocked with no problem.

They can handle 5 for sure. I wasn't able to connect 5 because I've used them for S2-s and didn't soldered enough cables on them.

So you have 4200Watts running 4x S3 units?

or 8 units 4 on each one?

4 on each one.

Please provide watt usage at the wall and a picture of setup, would really help

I'm not running them at home. They are built in at my mining place.

I can take some photos but only when I clean them in the near future.

Not sure what to make of your comments, no factual figures or pictures.... im not convinced you even have a setup. Anyone who is carrying out an install of 8 units is surely to have recoreded some testing or taken pictures of the modifcations etc.

Maaannnn..... Please.....

Check my sig and my old account. I have 70+Th running. Do you think I make a picture about every cable what I make... Huh

I've tried to help you out buddy but now I think you're just an other stupid wannabe clever guy... Sorry for that....

Not stupid, certainly not a wanna be...a just new hobby

So your telling me you have 70TH and you dont have one stat or picture....come one dude!!

I just dont see the point in someone posting '' Yeah I have two of those PSU's running 4 units no problem'' wheres the science in that. All of these questions I'm asking will be answered, then once my setup is up and running I will post back here with the facts. Not just ''Yeah I have two of those PSU's running 4 units no problem'' ... Sorry for that....

But hey thanks for your help

Hello

So I have 4 x S3 miners coming next week and I’m just about to buy the power supplies. I was thinking two Corsair HX850 (850Watts), only snag is they have 6xPCI-E 6 connecters and the miners take four each. Would like to over clock them abit and concerned the wire will heat up to much.
http://www.corsair.com/en-gb/psus/hx-series

I know they can run on 2, I’m wondering if I could connect three to each miner or will it only work in arrangements of 2 or 4?

Looked at this guide which is great but isnt that detailed.

Thanks for this, but im not sure its the best way to go only using two cables pair one device.

Cant wait now to get my gear, going to take loads of pictures and watt readings then post on here.

Thankyou all for replying

Ok, it looks like there is some debate on what better, server PSU or ATX PSU. I can’t find any Watt readings at the wall for server PSU on YouTube, just ATX PSU so I don’t really have much to go from in form of statistics.

In the UK electric is no cheap and even though an AXT PSU costs £70-80 more, over the duration of its use, I’m thinking the usage will be lower.

What about a pair of 1000W EVGA SuperNova G2 Full-Modular 80 PLUS Gold ATX-PSU. Looking at the picture it has 8 slots for power.

Am I correct in saying, use the VGA and CPU slots Huh

do they provide the same power output

You could run on 3, but the load won't balanced across the 2 cards - one card will only have 1 cable powering it and that cable will have the highest risk of melting.

You could buy PCI-e splitters and run 3x PCI-e cables (2 + 1-into-2) per S3 miner. That way you can balance out the odd cable across the 2 cards.

just throwing this in: I sell spliters perfect for this (see link in my signature) Its a 1->2 Y-shaped PCIe cable made with quality 18awg, 6" per arm (12" total length when spread). Can easily handle 140W/arm, more than enough for the S3+

Its better to buy an server PSU wich is more efficient more reliable and much easier to exchange when the break down. All you need is a server PSU + a breakout board.

I have got an IBM DSP2000 PSU wich can go to 2500W or 200A on the 12V rail.. no PC-PSU can beat that (bought it for $ 45)

Interesting, are the server PSU's even better than the 80 Gold Rated ATX PSU's. I have seen on youtube some guy tested a crappy PSU against a Corsair and the difference in power usage at the wall was 120watts! The crappy one was pulling 470watts and the Corsair was pulling 350watts thats alot if your farming.
Do you have any brands of server PSU and breaker boards...im in the UK.

god no. ATX Gold is way better than a lot of server PSUs, particularly the Corsair series. I own an HX850 in my GPU rig and it holds its own. Quiet and power efficient. I have no concerns about it being 90%+. Most server supplies ive seen though are extremely loud, the custom cabling can be an issue to solder or source parts, and often the best deals are on used/refurb units that may not stand up to standards after the original usage.

That said, server supplies are good if you want to save some money (which IMO quality PSUs have resale value and work better/longer than server gear) or where PSU space is an issue and high-density gear is an issue. But for the home miner with a pair of S3+ miners, the HX850 with 6 cords spread between the 8 slots (4 would do, but why not all 6

) is sufficient for stock speeds, but you wont be able to overclock, as anything over 390W/miner (about 480GH/each) will start pushing the PSU near limits and lose 2-3% efficiency. To overclock you should use an HX1050 or better

If he OCs the S3+s with 2 on an 850w wouldn't he be pushing the PSUs to the limit? I would get at least a couple 1kW PSUs if I were you. You'll get better efficiency from the PSUs that way.

You only need to use 2 PCIE power cables per S3 - no need to use 4 per miner.

Really?..

Very true. If OC then suggested 4. But 2 cords can easily do the 220 or so watts each. Just have to make sure to plug one into each blade.

I have been running 2 of my s3 with 1000 watts server psu with no issues. Another plus is that there is less wires and they are cheaper then a regular psu.
