Thanks for the formula reminder, but is it the same for ac and not dc?

So for those that operate on 240v will be double with a zero behind right?

wah...
abit wasteful leh...
330w psu to run few fans...
but if u want.. its also possible la...
U just nid to short 2 pins together to on the psu...( in order to "start up the psu when plug into the wall socket.. as normal psu wont run when plugged in... u nid to on the on button @ the comp.. which this doesnt... So u nid to short it to let the psu think u have power on the comp)

but i 4get which pins liaoz... (possition is ard the centre of the connector connecting to the mother board)

note: shorting of the pins would nid modding of ur psu thus no warranty would b covered...
