RE: How to convert an ATX power supply to rc use
Alright I am attempting this but I have a few questions.
It's a 450w ATX switching power supply.
The wiring is wierd, at the P1 connector (20 pin) There are 2 sets of combined wires.
Orange and Orange
Black and Black
They are not darker nor lighter from the rest of them but I am assuming they are the sensing wires, I soldered orange to orange and black to black.
I put the only green wire on a switch with ground
Gray is not connected to anything as of right now cause I'm going to be using it as a LED.
Now, since I am snowed in I couldn't go to radio shack but I found a car bulb to use to test.
First I tried the yellow and a ground with OUT a load on the 5v rail. I got nothing.
Then I tried to use the bulb as a load on the 5v rail and when I flipped the switch, the fan did not turn on. Now I know you say don't assume the fan works. Just assume that the fan works.
What am I doing wrong? Any ideas?
