Sorry I forgot my psu, I've got a Corsair CX500 v2, which is supposed to be pretty decent. SpeedFan is showing voltages lying at pretty normal values. Don't have anything else to test with.
CPU temps also seemed normal, though they did spike up rather rapidly (from 40-50°C) but still never going higher than ~65°C(150F)
Didn't monitor PCH yet, will check that out when I can.
