psu problem

hellzknight · 30-July-06, 08:00 PM

Well i went to repair two computers my freind has at his house, one is a hp which was removed from the original case to a thermaltake one. The other is a custom made computer. Both had psu problems, on the 5v rail. They are on surge protectors, so its weird. The hp one worked perfectly for about 5 years. The other one is 1 month old. Anyone got any ideas what caused this? Also the hp one the bois said the -5v rail was running at freaking -61.48 WTF??? any thoughts??

Have you measured the 5V rail with a voltmeter, or are you relying on the motherboard sensors

Please post more info if you want help. What was the problem? are the systems unstable, crash only while gaming, etc?

I have seen PSU problems that resulted from a bad fan causing the PSU to overheat. Once the fan was replaced everything was back to normal.

What brand is the power supply in question? If it's generic
then you have part of your answer :-) Sounds like he must
of got a big surge.

it is generic but they both died at the same time. the computer would not detect the hard drives on either of the computers, when i tested with a psu tester the -5 rail led would not light -_- weird

If they both died at the same time then he got a
big power surge/spike. The HP may need a P/S
from HP. Almost any P/S should work for the other.
I recommand getting a decent brand name P/S :-)

i replaced them already, the motherboard on the hp was change a couple months back, so it supported any psu
