I found the skeleton of an old computer with the power supply in it
that still worked. The power supply will only turn on when it's
connected to the motherboard. I'm trying to figure out how I can turn
the power supply on without the motherboard.
This is (was) a pentium II and the power supply says "Newton"
something, but I don't have the model number with me.
The cables that go from the power supply to the motherboard, in
addition to the usual red/yellow/black power/ground lines, have orange,
green, blue, violet, grey and white wires.
I was hoping there is some standard color-coding for the "power good"
wires that I have to jump or whatever the procedure is, to get the
power supply to turn on by itself.
1. Google for colour codes.
2. Switch power supplies do need a minimum load for operating.
Never trust color codes because
A) you can't be sure a company follows them
B) even if they did, you can't be sure that one specific power
supply was wired with the wrong colored wire. (Not likely
for a mass-produced item, but not unheard of.)
Either the pinout on the connector is standard, in which case they can
look it up, or it's a proprietary pinout and one has to find the
exact pinout used by the specific manufacturer. But in either
case, the pinout is a far better method of figuring out which wire
is which than color coding.
