+12V Question

Is it abnormal to see my +12V occasionally drop to 11.75 when running OCCT to stress my CPU overclock ?

Just going by what OOCT lists, I don't own a multimeter.

never trust in any software monitoring tool for voltages... completely unreliable. however as said if you measure properly with a cheap tester or multimeter above you are still withing ATX specs, however just imagining it was a real case with voltage drop by stress the CPU I would change the PSU instantly as a CPU never should mean that kind of current burden to make a PSU drop. it mean that any recent GPUat heavy load (specially if overclock are taken into consideration) can drop significantly the voltage under ATX specs and damage your machine.

Go and buy a cheap tester and report back..

Yeah, a lot of those cheap testers can be rather inaccurate compared to the higher end multimeters. The sad part? They're still a TON more accurate than the on-motherboard sensors. (background info: I have a generico cheap chinese one, works for me but zero fuses so it's a problem waiting to happen, likely never going to trust it measuring current, only low-ish voltages)
 
The ATX spec is ±5% for the 12V, so 11.4V as minimum. I don't know if it's abnormal, but there's still no reason to worry, even if the motherboard reading is slightly off compared with what you might get with a multimeter.
