Just put together a computer. When I turn on the power supply (rocker switch on the back) alone without ANY connectors connected, it doesn't make any noise. But when I connect the ATX power cable to the motherboard, and then turn the power supply, it starts making a very annoying hissing sound, and it's fan doesn't spin. The power supply is 400W, and the motherboard is Asus A7V8X-X. What can possibly be wrong?

Sounds like something is short circuiting.

I love my Delta 60HP 7000 RPM fan that puts out more dB then CFM :eek:

it just sounds like a cheap psu. they tend to do that, could mean its about to die, could just be making noise for no reason. try banging on it, works for me
