Power supply turns on pc and fans when plugged

[papa_3]

I have this thermaltake se 730w gold and everytime i plug it it it automatically turns on and i tried doing this power supply test http://m.wikihow.com/Check-a-Power-Supply but without using a pin it still turns thenfans on? So i assume i have a bad supply right now?

There is a BIOS setting intended to ask "what do you want do happen when the PC suddenly loses power then the power comes back? do you want auto reboot, Yes/No."
