No sure I like the idea of using server PSU's.... noisy and I doubt they are very efficient, but hey thanks for the input. Im going to buy ATX PSU's Gold or Plat rated.

I found this video on you tube and this guy has them cross connected each PSU powering 1.5 miners. I didnt know this was possible for the S3+, would someone please confirm its safe.

So if I got the EVGA SuperNOVA 850 G2 this has, 6x 8pins on the rear so I could power 1.5 miners?

Most of the times server PSU's are more efficient that ordinary pc-psu and a lot more robuste and tollerant. they are designed to run 24/7 near 100% load. dont trust your feeling base your decission on facts and look it up in this forum.

I have 5 EVGA G2 850W units powering 10 S3/S3+ no problems; no need to use paperclip to short the pin on the motherboard connector either - the PSUs come with a adapter that will short the pins. You only need to use 2 PCIE power cables per S3 - no need to use 4 per miner.

Also using EVGA G2 750W units to power AM Prisma (2 per Prisma)

If you happen to be in USA; Amazon has the best prices on the EVGA G2s and their MiR will cover up to 2 PSUs.

I have used the Dell 750W Server PSUs w/ breakbout boards; they get pretty hot; even with the fan turned up. I sold 2 of tyhem on eBay - kept 2 for spares; so I could setup miners in my office before they go to mining room in basement.

Have you overclocked them? I thought if you ran them with just two cables they would burn up?

searching these forums, you'll find the ratings of many power supplies so you won't need to speculate as to how efficient or noisy they are. Failing that, google it.

Great advise there mate, dont give up your day job! Roll Eyes

Anger is a gift.

Check sidehack's group buy out. I have 6 of his PSU's pushing 11 of my S3's, with 1 PSU for 2 miners. They have been working perfectly for a while. These things are loud, but they are the best PSU's for the money.

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.

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.

Personally I have been using the RM1000. No problem powering two. Its also a very efficient PSU.

My biggest thing is i prefer to go gold on power supplies even though it is higher then if you go with a bronze something else.
