  1. Hi all,

    Just got this new power supply for the PC I'm building. The case and PSU have been the first things to arrive so I dotn have anything else yet. I bought the PSU (X-Power 700W) from eBay, the seller had a few of them and said they were all tested and fully working. I fitted the PSU into the case and tried to test it by connecting the two case fans and case LED lights to it. I switched it on and got nothing. Not even the fan on the PSU fired up. Does this straight away mean the PSU is faulty or could I be doing something wrong???

    It wont

    For the PSU to be activated just flipping the switch on the back will not do it. 2 pins on the big 20/24 pin molex have to be jumped. You can do this manually but i dont suggest it cause you can burn out your power supply if you jump the wrong pins. But if you must, google it and you can find a guide somplace im sure that shows you the right wires to jump. I know wich ones to jump but I am not going to tell you and be responsible for you ruining your PSU.

    These pins are jumped when you connect the 20/24 pins to the motherboard and then the switch comes into place when you hook the front panal connectors of your case to the motherboard.
