Hey guys I got my 2nd 7970 today, so i installed the waterblocks on them and installed them on the computer. I overclocked them to 1100/1500 @ 1.175v using TriXX. So i run the bench and when the 2nd test tries to load my computer turns off. I set GPUz to create a log file so i could check the temps, and they did not go over 52c. I'm thinking it's my power supply, but it's 1K watts, but I've had it for a few year though. When I ran these test with a single 7970 my computer did not turn off at all. I could even push the card to 1200/1800@ 1.2v and no shutdown, completely stable. Any thoughts?
