How do I test a Power Supply?

I got a new Antec PS. But when I plug it in
(with nothing connected to it) it doesn't seem to
run (the fan doesn't turn and there is no dc voltage
on some of the leads). Is it dead or does it require
a connection to a motherboard to work???

Thanks

It requires the green wire on the big power connector (has 20 or 24
pins) to be grounded to one of the black wires (any will do, even
others on the same connector). Most people use a bent paperclip to
short them together.

BTW don't bother buying a PSU tester because it will say that a PSU is
fine even if one of its voltages is so way off that the computer won't
run. In my case a tester from CompUSA did this even though the +12V
rail was too low to make the disk drives spin. For the same money you
can buy a cheap digital multimeter that will be a lot more accurate and
useful for testing many other things as well.

You may notice that the power button is on the case and connected to the
motherboard so, yes, the PSU normally needs to be connected to the
motherboard to turn it on.

You can power it up separately by connecting the green wire to ground
(black) but it also needs a minimum load to regulate properly. I keep an
old junker hard drive to plug into them for that purpose.


Thanks

Plug the power supply into the mains. Drop your knickers, squat over the
vents and **** into it.

PS: Do you suck cock? Do you swallow?

Read up about Switch Mode PSUs - they need a load to run

If Pac-Man affected us as kids, we'd all be running around in darkened
rooms, munching magic pills and listening to repetitive electronic
music.

Hmm! Good idea.

Thanks to all (except for the one jerk). I did as you said and it does
read the correct voltage now but the fan still doesn't turn. Is it normal
for a Antec SL300S to not turn on fan until hot??
Thanks

Which fan? (I missed something?) I would think th eprocessor fan would
be going all th etime, dont try if it does not. Other fans may be on off
temperature controlled maybe?

I suppose a head job is out of the question then?

Sorry, but the tweezers have been misplaced.
