I think an 80 plus platinum PSU efficiency is around 92%
6x120 watt is on verge of your PSU limit and it's natural to give up and lose GPU.
Either lower your power limit or use higher PSU

I think there is some confusion here. Only 6 risers are powered by the EVGA. ALL cards (6+2) are powered by the 1400W PSUs. 7 (6+2) on one 1400W, 6 (6+2) powered by the other 1400W. The X-11 breakout boards are connected via a Molex to the mobo so all PSUs power on/off at the same time.

Usually lost GPU cause by high power or over clock, try to lower and find the spot with no errors, then raise slowly.

But should't watchdog be restarting the rig on any error? It's seems the GPU crashes and it freeze's / crashes the OS as well.

Power limit is set to 125W, so essentially 85%. Core 100, Memory 475.

Rebooted the rig due to this error at 10PM, it's now 11AM and all is fine with no settings changed. The only difference is that Quake isn't opened (when the rig boot's only terminal opens and start's mining) but I usually open it to view what's going on. Obviously it is running in the background, but this is just not consistent at all so it's difficult to pinpoint.
