1700W for Six 7950's?

[Ratman2050]

I am running this setup:

Intel Celeron G1620
32GB SSD
4GB DDR3
ASrock PRO BTC 81
Cougar 1000W PSU
Cooler Master 700W PSU
6 - 7950 (Powercolor, Sapphire, 2 GB WF3, XFX, His IceQ)

I know, I know, I should've bought the same cards, but this was my first rig so I didn't know how much of a hassle diff. cards would be. For my 2nd rig I got 6 Sapphire 7950s. Anyways, I am a little worried though.

I have 4 7950's on the 1000W and 2 7950's on the 700W, the 700W also powers the mobo. I am bit concerned about the 1000W psu not handling the 4 7950's, do you think two 850W would be better? I just don't want to keep buying stuff since I just finally after weeks of testing got the rig running.

These cards are not really OC'd right now, they are running at 17/18 I and most are at 1000/1250 clocks. I think most cards are 1.25v but 1 or 2 might be 1.09v.

Here's a pic:



They have been running for more than 4 hours now..

In view days my (first) rig is complete in nearly the same config.

1000W + 650W LC-Power Gold. each.
6x Sapphire 7950's DUAL-X @ 1,092V

I will inform you how its going.

btw. you can tweak your voltage for each card with this method, which works in smos/bamt as well:

Well I have run it for 3-4 days so far without any problems, it tripped the breaker when I used the microwave but I don't use that anymore..
