During timespy loop, the PSU trips off from what appears to be an overvolt protection. Watts at the wall (120v socket) hover around 890-1000W.

PSU is SeaSonic 1200W (100AMP 12v)

Rig in the signature.

Only crashes when GPU's are overvolted to 1212mv and running 1200 core. When I run at stock speeds/clock, no crash.

Processor is OC to 4.2 but HT is off.

Am I pulling too much power through the PSU or is it faulty?
