    Evening folks,

    We recently had an issue in the house with one of the lights causing a power trip (I figured it out cause my speakers were crackling, Monitor was flickering and PC was turning off at high loads). We fixed the trip and everything went back to normal.

    However since then Ive noticed that my speakers do an odd pop now and then (Rarely), my monitor flickers at bootup (only bootup, and only occasionally) and makes a funny noise on standby, and when I stress test my PC (Furmark Multi-GPU) it cuts out after a few minutes/seconds (after my cards have heated up and are using full power)

    Can any of you guys link this all up? Is my house electric still a little f**ked? or has it damaged my PSU?

    Ive tested my cards at the following settings using Furmark 1.9.2 with the lastest 295.xx WHQL Drivers.

    950mv - 675/1350/1700 - PASS
    1000mv - 675/1350/1700 - PASS
    1050mv - 675/1350/1700 - PASS

    1050mv - 750/1500/1850 - FAIL
    1035mv - 750/1500/1850 - FAIL
    1050mv - 800/1600/1900 - FAIL
    1035mv - 800/1600/1900 - FAIL

    I used to run these at 826/1652/1933 @ 1037mv with no hiccups...

    It seems that the power trip has either damaged my PSU, my plug sockets or its pure coincidence that my Cards have failed on me at the same time this happened.

    Something to note, I salvaged 2 PCI-E Power connectors from my Thermaltake Toughpower 750W because the ones from my Antec CP-850 have gone missing. (Was using A combo of the 2 remaining PCI-E connectors and 2 Molex to PCI-E adaptors to run the cards) When these are plugged in to the respective modular connectors on the PSU, I get NO power to the PC. Not even a mobo light.

    Any input would be appreciated.

    Thanks in advance
