how test a power supply?

Not a particularly easy thing to do properly...
Here is a basic tester, but this does not tell you if the PSU will work properly under load.
Whilst it might get a pass with this type of tester, when the PSU is powering a motherboard, several hard disks, DVD drives and fans, etc., it might suffer from voltage sag on one or more output rails.

I've seen quite a few power supplies that have passed my power supply tester test yet no boot. But, when I connect another power supply to the system - it boots.
I think the cheap testers are basically worthless. You would need one that puts a load on the supply and tests for ability supplying voltage under load.
The best test if you suspect a bad power supply is hook up another one. You can do it without actually putting it in the case. Just let it sit outside the case and plug it in. I normally only plug in the essentials (mobo, P4 plug, etc.) and not the peripherals (hard drive, optical drives).

I agree completely, only have had the exact opposite experience, a working PSU tests bad with a cheapo tester, but works fine under real load.
I've given up on the plug-in checker, I use a $30 PSU tester called a $30 PSU.

I always start with the easiest solutions. Pull the side panel off & turn on your unit. If you don't see a green light on your MOBO & the cooling fan isn't turning, you're psu has gone to cyber heaven. As goombawaho mentioned, try an other psu, but I usually plug in the HD to see it it will boot. Or you can pull your psu out & see if it will work in a different PC. You can get a fairly decent 400W for around $50 but that depends on what is running on your system. The site below will test your system to see what wattage psu you should have to run all your components.

Dito the above....although I have this PSU tester and have found it very useful.
You are right...it won't test under load but it has saved me damaging other components several times.
