I'm putting together a new computer. Nothing is installed in the case yet except for the PSU. I have an ATRIX case that has a built in multifunctional PC temperature controller display and clock. I want to power the PSU up to test the voltages and to power up the display unit to make sure everything works before I install the motherboard and drives.
The PSU normally powers up by the botton on the front of the computer when everything is installed to the motherboard and the 40 pin EATXPWR connector is plugged into the board.
But there is a way to power the PSU up without being installed on the MOBO as I've seen it done before in a computer store. There are 2 pins that have to be shorted out on the 40 pin EATXPWR connector but I'm not sure which ones? One of the pins are marked PSON# which has to be on of them, but what do I short it to, +3, +5, +12v, or do I short it to ground.
Does anyone know how to get this PSU powered up just by itself.
I know it can be done because the store where I bought the case had one on display with just the PSU installed in it and the had the built in temp controller powered up and the lights in the case were working. I would ask him at the store how to do it but it is closed till Tuesday and I want to get this done this weekend :-)
