Seasonic S12-600W PSu Problem :(

[jackvdbuk]

hi, just tried my PSu which ive kept for about 22 months in its box, and it doesntwork i connected a fan to it (my newly bought SIlverstone ones ) and it doesnt spin, i triedthe same fan on my PSu in this pc and it works fine.... i have no idea what i could do or try...

Erm... the fans won't spin unless the PSU gets the power on signal from the motherboard that things are go... which gets it from the case power switch.

You can trick it into switching things on, but I don't know which pins it is.

Even shorting the pins to start the PSU may not work as the fan won't put much load on the PSU, and it will shut down again. You need to attach it to something thats going to draw a decent amount of power to test it properly.
