I haven't, in the quick research I've done been able to figure out just what signal to pin 14 it requires to keep the supply on. Perhaps a short to the 5v or 3.3v line?

I'll keep looking.

Anyway, if you want a portable power supply, why not just get an adjustable supply? PC supplies vary a great deal in quality, and some are downright junk. Or, use a battery and construct a voltage regulator to step down to whatever voltage you wanted.

I'd hate to have to drag around a atx supply, especially if you have to get it through airline security (a box with lots of wires coming out of it)!

Thanks for the page it actually helps allot. I have a decent power source and i have an adjustable power supply... which has fried many a electronic when it was accidentally set to the wrong voltage. Also most 12volt battery packs are rather large (yeah ive seen small ones refer to next line) and I don't want to have to keep charging them. Plus over time they wear out and 12volt rechargeables aren't cheap. Finally im not worried about airports. I live in Virginia which is a short drive to regionals and a (slightly longer) drive to nationals. We don't go through airports but i cant see them taking a power supply if you checked it in.
