Re: PSU Query?
Are you too lazy to provide the details here? I know I'm too lazy to
look up your earlier post.
You and all life within a 3-mile radius will likely die within minutesm
while enduring more pain than if you simultaneously passed a kidney
stone, had your teeth pulled, and were Tasered. But more importantly,
no harm will come to your computer because very, very few require the
extra current capacities provided by those four extra wires, so it's
definitely a worthwhile risk.

I realize it's a bit late now, but ...
If you're just testing the theory that the new 24-pin PSU is dead then you
can certainly connect the old 20-pin PSU -- the 20 pins connect with one end
of the 24-pin connector so that the 4 unused connections are all at one end
(the connector should be keyed so you can't get that wrong).
Do this with no memory, disks, graphics card, etc., connected, and see
whether the standby power LED on the motherboard lights up. If it does with
the old PSU and doesn't with the new PSU then you know that the new PSU is
dead. If it doesn't come on with either PSU then the fault is probably a
dead motherboard, a short-circuit, or a duff fuse in the mains plug.
Be warned, though, that if your motherboard is faulty, or there is a
short-circuit, you might damage the PSU by trying this.
Note that you don't even need to turn the PC on to perform this test, so it
really doesn't matter that the new motherboard may require more power to
*run* than the old PSU puts out. However, you may be able to run the system
off the old PSU. Most 24-pin motherboards will work with only a 20-pin PSU
connection (and others will work with a 20-24pin adaptor). You shouldn't be
able to damage anything by having too little power, but the system may not
run reliably (or at all) -- especially if you have a high-spec graphics
