-12v drops to -16v when stress testing

post #1 of 7
Thread Starter 
Just curious if its normal for the -12v to drop as low as -16v?

As far as I'm aware that rail doesn't actually exist in modern power supplies; pay it no mind. While on the subject, don't rely on software for voltage readings, only hardware.

this, I've had HWMonitor report 7.2 MW power usage on my i7 970, somehow methinks that is quite impossible. smile.gif

Thanks, just curious. Thought maybe this was why my 1055T was having problems OC to 4.2Ghz even though temps were okay.

Software monitoring sucks.

I think it's still there, it just isn't used.

Yeah, -12V is still required, but never actually used. A few milliwatts of resistance from passive motherboard circuits and the wires and that's it.

-5V, on the other hand, was removed from the ATX12V spec in 2003.
