I burned up two OCZ 700w PSU’s, yes Sparks & Smoke, before I figured out that everyone serious here uses Corsair; so I bought one last year and never had a problem, see below for what it is powering.
Since I just added a second ATI card in Crossfire, I’m working on getting F@H up on both to see what kind of performance boost I can get. I want to run Folding@HOME at about 20% overclock 24/7/365 on both video cards running two installations since Crossfire and F@H don’t play together. It looks like this can be done by actually duplicating the currently installed client running on GPU 0, essentially creating a second installation and running it on GPU 1. I am using the instructions from F@H here that appear to be pretty straightforward (to me at least).
F@H moves out of the way whenever GPU is needed for other applications but I’m interested to see if I get any Crossfire conflicts when this happens.
I got a performance bonus at work in 2010 and again in 2011. I’ve been spending a little of it on upgrades and future-proofing so I need to update my sig:
