Hello guys,
Recently my pc start giving BSOD, and 2 days back when I restarted it, it would not turn on. Only green light on motherboard stay on, when I press power button nothing happens, no beeps. No fan spins at all.
I have tested my power supply with multi-meter and found that PSU is not working properly, its turns on but giving wrong output. Please see below my results.
Yellow=+12|Mine=15.40 Red=+5|Mine=6.57 Orange=+3.3|Mine=4.34 Blue=-12|Mine=14.50 Purple=+5|Mine=6.36 Gray=+5|Mine=6.55
i sent my PSU for RMA and now overclockers technician decleared that PSU is working 100% fine, i just asked them to plz check PSU incoorect output, as this is the cause for no response for my MB or CPU, any suggestion for ur side?
a PAU with these wrong output can be dangerous?

First make sure the multimeter is calibrated, (there an internal battery inside of multimeter, if the battery weak the measurement can go off)

If those reading are correct it will very bad for your system...

Try contacting the antec support take a picture of the multimeter if u had to...

Thank u for reply. can a PSU with these wrong output power up a system, perhaps this PSU has already killed my MB and Overclockers tachnician is able to get a post. perhaps PSU will kill overclockers MB if used for a long time? just wanna confirm. thanks

different mobo had different tolerance so it hard to tells, but constant high input makes the voltage regulator work harder and produce more heat...

how fast it will fail? dunno..

but since all rail had higher voltage, Try calibrate the multimeter first...
