Help me test my PSU, please

[Tsuul]

I am having difficulties with my board posting with my vid card in place.
The video card works in another system.
I want to test my PSU before I send my mobo off to RMA land and lose valuable $ and time.

I have access to a voltmeter with a bunch of settings and even better, I have access to someone who can use/read it. But what are we looking for? How much variance in the readings is ok, if any?

24 pin connector with clip on the left (pin 1 in upper right).


+3.3v +3.3v
-12v +3.3v

ps_on +5v

+5v +12v
+5v +12v
com +3.3v

4pin ATX12V1 connector with clip down (pin 1 in upper right)

+12v +12v

I don't care to test the molex connectors at the moment.


OCZ-520 12U


DC output +3.3v | +5v | +12v | -12v | -5v | +5VSB|
| | | | | |
max output 28A | 52A | 28A | 1.0A | 0.8A | 2.5A |
| | | | |
max cmb 260W | 336W | 12W | 4W | 12.5W | 620W
wattage 500W | 28W |


Thanks for reading and any help.

+or-5% variance is acceptable

[Tsuul]

So when I check the volts on the
5v pin, I should get between 4.75 and 5.25
3.3v pin, I should get between 3.135 and 3.465

Your answer was clear and concise, it's just that it's electrickery I'm dealing with and need a double 'yes' before I recreate bad memories of pins in socket holes.=)

Thanks for the quickness.

[malinois1]

that is correct and 12V between 11.4 and 12.6

He's right, 5% fluctuations, you should be fine.

Great!
Thanks again.
