Hello
So I have 4 x S3 miners coming next week and Im 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.

I know they can run on 2, Im 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.
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
