when you short green to black wire

I assume you've disconnected the 20-pin plug and the 4-pin
processor 12V plug and the disk drive plugs and the video
card plug to isolate shorts.

I have seen many P/S that do not conform to
the color code.

The loading is very important, the PS won't stay on for more thanThe green must be connected to COM before the supply starts. The purple
is just a always on and it seems it's working.
Just connect the green to black, and put a small load on one of lets
say one of the RED wires (5 Volts).
Open up your PSU & look for a blown fuse.On Aug 20, 9:43 am, spamme0 <spam...@netscape.net> wrote:

when you connect green to ground the fan starts spinning briefly

Not that I know of.is there a generic 300-400w atx schematic someplace because google-ing
as "Rexpower" did not help
