I have the following set-up:
Corsair AX1200 1200W PSU Asrock Extreme 4 MB 4GB RAM 3xSapphire Dual-X 7950 GPU 1xAsus DC2 7950 GPU
2 x16-x16 risers 2 x1-x16 powered risers
After first stable setup (no HW error, very few rejects), power from the wall was 1100V (OC and powertune). After 3 hours, the computer shut down. No error, no nothing, just shut down. I have decreased the clocks and disabled powertune. The power from the wall is about 900W. Still, about 3 hours after starting, it shut down again.
What can cause this? A faulty PSU? Can it be something else?
Thank you.
