Just put a new pc together this week and once I had finished with all my installing, downloading and patching I decided it was time to give it a shake down with a few games, only one problem, the game starts up and my pc shuts down. I'm using: Asus P5Q-E Green Intel P45 Socket 775 Motherboard Intel Core 2 Quad Q6600 2.4Ghz 4x2mb 1066FSB CPU NZXT Tempest Blk ATX Mid Tower Case with 6 fans + cpu fan OCZ Vista Upgrade Edition 4096MB PC6400 DDR2 800MH. WD Caviar 160GB Serial ATA HD 7200/8MB/SATA 3G 2 - VisionTek ATI Radeon HD 4850, 512 MB video cards ULTRA X3 850W PSU After all my searching all I found was one review of a Ultra X3 1000W PSU, and the review pretty much described what I was experiencing, saying that the psu would either burn out or just keep shutting down while playing games. Both my cards require a 6 pin connector and the psu seems to support that just fine. I guess I'm just looking for confirmation that this is my problem and the solution is to find another psu or is there a work around or fix that some one has first hand knowledge of, and if it is the psu that caused all of these problems for me and might have damaged my new components do I have any recourse against Ultra or tigerdirect for selling this?
