View Full Version : How do I turn on an AOpen power supply

Does anyone here know how to turn on an AOpen FSB235-60GT power supply?
The power supply is removed from one of my old computers and can be turned on only when attached to the main board and then pushed a button at the computers front panel.
One of the output cables is white and called P.G.signal, I suspect that cable has a key function here.

My plan is to use the 5 and 12V to run a Dell LCD-screen with broken power supply board.

You need a load on the 5V output, IIRC.

I'm not sure about your particular model but a lot of computer power supplies need the "power on" pin shorted to ground to work.

I've also read it's a good idea to provide a load to the power supply using an old hard drive.

This article helped me understand thing when I reused an old power supply.

SparkFun sells these (http://www.sparkfun.com/products/9774)that make it easy to use an old PC power supply.

Free day starts in two and a half hours, maybe you could get one for free.

Thanks a lot for good help here, the LCD screen is up and running now!

How did you get the PS to work?

Hey, Leon!

Pretty easy, simply by connecting pin 16 to ground, but how could I know that!
