Hey OCNers I am thinking of tri SLI'ing my GTX 285's and was wondering what PSU would be good? Currently I have a Corsair HX1000W. Would this be sufficient? Rig in the Sig

HX1000 would be more than enough - I had 3X 580's overclocked on an HX1000 and there was still room to spare

Tweaktown when doing the review found that their system was using ~ 700W of power (bare minimum system) so yours MIGHT use ~ 800 - 850W

If it has enough connectors I'm sure it will be fine. It's certainly enough in terms of the raw power, although you may have to be careful in how you wire it. You'll want one GPU running on the same 500W PSU as the CPU, and the other two cards running off the other 500W PSU.

First off thanks for the replies. I just got my cards now. Plugged them in and tried to activate SLI. However only the first 2 cards are SLI'd. I know I am not being descriptive, but I am very confused at the moment. Thanks for your help.

How about would you out the cards on different 500w? Physically which plug goes where?

Faulty SLI bridge?

The hx1000 is 2 500w power supplies stuck together, so you need to read the manual and find out which connectors go where.
