Thanks all!

sniffle, are you saying that ATX power supplies do not have replaceable fuses?

lovincup, I am using a 1 to 3 outlet extension cord, it does not have protection. I'm still successfully powering the rasberry pi power supply with this extension cord.

TopJimmyCooks, I forget exactly what I did (I'll have to go back and look) but I followed Colin's 8" i3v build guide to allow the ATX power supply to power on.
