voltage issues

post #1 of 10
Thread Starter 
my psu is currently running 9.854V on the 12V rail and 5.7V on the 5V rail. is it just that i have too much stuff thats causing the problem? or is it just a POS power supply. A new psu is on my list of new stuff to buy. i was thinking this one http://www.canadacomputers.com/produ...item_id=031934 my case actually has 2 power supplies because i ran out of spots on the psu to add any more cables. and is it totally safe to have a card half running off an old crap psu that sits in the 5.25" bays? or is it just ill advised? sorry for the n00b questions but power supplies is the one area i dont know a whole lot about. thx

What are you using to measure the voltages?

Yeah, software is rarely (if ever) a reliable option for PSU rail monitoring. I highly doubt your Ultra is a good model, though, so a new PSU would be a good idea, especially for future upgrades.

The only good way of measuring your PSU voltages is with a voltmeter.

My 12v reads in all software as 13.3, and the 5v rail reads as 3.5. It's nowhere near any of that when I test with a voltmeter.

i doubt it could be THAT inaccurate, and my friend bought that psu a few years back, i think its gonna be the next thing to buy then because id like to still have all my components in a non-melted state while i fold.

It is that inaccurate. Software monitoring sucks. Hard.
Trust me, your computer would not be operating properly at all with those voltages. Although your PSU probably isn't very good, 9.854V on the +12V and 5.7 on the +5V would simply not let you use your computer at all.

It is. Your system probably wouldn't be running at all if it really were those voltages.

Software monitoring = fail.
Get a digital multi-meter onto a molex and then tell us what the real voltages are.
Your GTX460 wouldn't be running if there was under 10v on the 12v lines.
