Testing PSU

I have a PSU laying around that I want to sell to give me budget for an upgrade but I wanna test it first before selling. How would I know if it's not a BAD psu?

HISTORY: I built my rig back in the Philippines where we use 220V. When I moved back here in the US, for some reason my computer would not post. I tested the PSU on a 20pin (not 24) motherboard and it powered up. I contemplated that my board died on me got an RMA. I don't know what killed my board either during the shipment (plane as a baggage, static?) or from the psu (from switching to 220 to 110 though it's autovolt). I occasionally use it to test fans and stuff.

After I got my RMA I bought an HX1000 just to make sure I won't be having a troubles. The local PC store couldn't tell exactly what killed my board he said something about my psu having the 3v (or 3.3v?) a reading LITTLE below normal. Still he couldn't give me a straight answer.

PSU is HEC Cougar 700w 80Plus bronze

The problem is you can't properly test a PSU without a lot of test gear. You can check that it powers up and measure the idle voltages but all that tells you is that it's not completely dead not that it's working properly and safely.
 
Yeah that's true but I'm more concerned on powering a rig with it. Can it kill a motherboard on start up? I tried with an old motherboard with 20pin and got it o post. I only have one 24pin motherboard that I can stress the crap out of it but I don't wanna jeopardize it.
 
All those extra pins on the 24-pin connector are in parallel with the same-colored pins on the 20-pin portion, so if your PSU passes with a 20-pin mobo, it will be safe to use with a 24-pin mobo.

PSUs are supposed to have undervoltage as well as overvoltage protection, and no-load voltages can be way off. What did the PC store find when they checked the mobo's fuses, MOSFETs, and voltage regulators?

Really? hmm i just too scared to try it on my rig. The fan is dead though I might have to change it. They never said anything about the motherboard, they just said it was dead I RMA'd it and got it fixed
