Power Supply DOA

[esteban]

Just started first PC build. Screwed in Antec 550 TruePower to case, connected case fan to standard 4 pin peripheral outlet on psu (not fan only outlet), plugged in the psu and turned it on (black switch from 0 to 1). I noticed that the case fan is not running. Then I noticed that neither of the 2 fans built into the psu are running.

Does this automatically mean that the psu is DOA? Is it possible that simply screwing the psu into the case has created a short. Does the motherboard need to be connected to the psu for the psu's internal fans to be running? What is the easiest way to test if the psu is DOA?

You did not turn it on. The switch on the back is essentially a failsafe - it can deny the PSU the ability to be turned on or not - that's it.

An ATX PSU must be connected to a mobo, and the power switch jumpers on the mobo shorted (i.e. through the power switch on the case).

anyways i got a bad psu with my case the first time i tried building a comp and i didn't think to try it before putting everything together. When it didn't work i was pretty depressed. I bought one of those gadgets i mentioned above and the psu got one light to brighten on the tester (theres 7). They can save you a lot of trouble, even with later "projects".

You can turn on a PSU by momentarily shorting two pins on the 20-pin connector, problem is I've forgotten which two, but you can look in your mobo manual and figure it out.

Edit: found it, pins 14 and 15, here's pick:
