Just left the system running for a few minutes and noticed the
familiar smell of electrical smoke. I believe it's coming from the
Antec NeoPower 480 supply.
I've had the supply for quite a while. Just got the new Asus P5K-E
motherboard and Q6600 CPU. I'm wondering about the chances that the
supply just burned out, and that the motherboard/CPU are OK.
The supply should have had foldback protection, so I'm not sure why a
motherboard load or short would have taken it down. Still...
The question seems to be whether to try a new supply, or whether that
may be toast after first power-up.
Random speculation welcome, especially if you've seen this type of
thing.

My random speculation would be, the Antec died quietly, and left the
motherboard alone. Slap another power supply on it and try again.
I test power supplies here, before I use them. What I did, is built
a load box, with a small load on each of the rails. There is an
80mm fan to cool the resistors and a switch, to turn the power supply
on and off (via PS_ON# and COM). While the power supply is delivering
about 100W or so total, I measure the voltages with a multimeter. And
let it run for a couple hours, just to see if it'll behave properly or
not. It isn't a Tomshardware style test, as I'm not aiming to overload
the power supply, and make smoke come out. It's just intended to prove
the supply is well behaved, before connecting it to a motherboard.

Personally I won't touch Antec PSUs.
I built 4 similar machines using Antec cases with PSUs built in.
3 out of the 4 blew taking motherboard + disks with them.
I managed to replace the PSU in the 4th in time.

Woke up thinking that today. The Antec's been in use for a while, and
I wouldn't be surprised if its fan died. I think it's about a week
over warranty so that would be logical.

Sounds like a good idea for testing the current supply too.
I do have some big resistors, and was considering testing the +5
anyway. I wasn't going to run it hot though...just enough load to
make sure the supply turned on. I was thinking about hanging a 4 ohm
off the +5 (only 5+ watts).
What value resistors are you currently using in your load box?

I don't have a particular preference but have had no failures (yet) with
colors-it.
I originally starting using them because they were quiet.

I am not trying to put you down or make you look bad but many find it hard to
believe that one person could have 3 out of 4 go bad yet hardly anyone else
in the world has that much bad luck?
what I do when I want a recommend piece of equipment is go to newegg.com and
read the
reviews. I have found that the people who review, tell it the way it is.

There is an example here. Note that some of the links on this page
would be dead, as there are likely later versions of the catalog
pages now.
