how do i test my stripped down psu to check if it works or not?

i had a mod where i needed to strip the psu casing to save space but my harddrive died and i wanna test if the psu still works fine.... im 99% sure it still does but is there some sorta procedure i must do to check if it works

so far, i plugged it in and fan spins and it looks fine but i dont know about the voltage stability or whatever

this is a generic psu but i had used it before i stripped it down and i know its a good psu... with some sorta quality

help... i need to finish my mod and i need to know asap

thanks
 
If you had a multimeter you could use that to check voltages and such....but if It was me, I would just grab another HD plug it in and see if it goes...

see if it goes what??? :eek:
;)

i have a multimeter... but is this a good way to test if it works good?... the only way im used to is plugging in the system and check but this ones a special mod i did and i dont think i can get another one of this motherboard so i rather not screw it up... its also kinda hard to take it out because i ran the wiring thru a lotta stuff

is there a standard way to check/test a psu to see if it works well?, or should i just use the multimeter thing?, or should i really take it out and try it on a crap system?

btw, my multimeter is the needle kinds with scales, not digital so it would be kinda hard to get accurate voltages

help!!!!.. thanks :)
 
I forget which pins, but you can short two of them on the atx connector to
get the PSU to fire up. Then test with a multimeter.

You may want to put some load onto it, as they don't like running without
out any. the up/downside of switching mode psu's.

I saw an article about converting an atx psu to a benchtop powersupply for electronics.
if you can find it, it had some good info, including ways to keep it from blowing up, and over heating.

good luck

Imo easiest thing to do is throw it in a crap system.

You can power up an atx psu by grounding pin 14 (typically green wire), but most units require about a 10% load in order to be stable. As you probably lack the high wattage resisters to provide this load, you'll have to run some drives or other components anyway.

The green wire (pin 14) to any ground (black) wire.

Yes, you need to put a load on the PSU.

yea, i know, green wire and any black... thats how i turned it on

so i think im going to try the multimeter thing but its gonna be hard to tell because mine isnt digital, its the scaled kinds with a needle

then i ll probably try a crap system then
