^EXACTLY

but i guess it doesn't matter when testing an 8-10 year old psu anyways.

or how long has BFG been out of business?

O&O shouldn't add any real load to the CPU, GPU or PSU, O&O is just a UI for editing your registry and a few other things.
However if you're editing running Windows functions while the GPU is banging off the power limit, down clocking/undervolting and repeating until the GPU finds a clock speed it can settle on, I can see you having any number of issues.
Furmark used to be a thermal test so that you could see if your voltage and power settings were able to be cooled by the cooler and powered by the PSU...to test overclocks usually. It's not a stress test and it never really was, if you use it to test thermals and power, you're doing it right. However now that GPUs clock speed and voltage fluctuate based on temp, you can't thermally test an OC this way because it simply won't hold the clocks. If we had full BIOS control we could force it to hold boost and voltage at a much higher temperature, I think they should hardware voltage lock the cards to an extent, maybe +10%, and give us full control over the rest. The voltage and power are going to stop scaling long before you risk damaging anything with voltage.

running O&O adds no additional load than running just furmark.

the scrolling was laggy as all hell, but i'm not surprised as i said, its just a GUI.

well since i have a minute. furmark isn't good at stressing the PSU w/nvidia card. since the 580/590 vrms going all popcorn, they have put the kibosh via drivers for furmark.

980ti w/350-400 watt limit in vbios - i have confirmed, long time ago in the 980ti owners club, that gpu-z reading is accurate comparing to a kill-o-watt and accounting for psu efficiency.

running furmark:

running kombuster fuzzy doughnut:

396 watts in gpu-z

if looking to really stress the PSU , kombuster looks to be better. run it w/prime, settings depending on the cpu gen and be prepared for the fireworks.
