Epik Posted November 21, 2010 Share Posted November 21, 2010 Another PSU question, yay. I recently upgraded to a Corsair 700w Gaming Series PSU. Well, I plug in all the components to my PSU and I get a 1 second run life and power down. I then have to unplug the PSU and back in to get it to run again for that one second. The tricky part is I know I didn't fry the mobo because when I connect my old PSU everything starts up fine. No issues, nothing. Reconnect the GS 700 and again one second and nothing. I have tried this four times now, test with the GS 700 and get nothing but a second of run life, reconnect old PSU with all hardware everything loads up fine, reconnect GS 700 and another 1 second fail. And yes I removed and put back in the CMOS battery. I have tried it with just the MOBO and it starts the fans for only a second then powers down. I have removed ram sticks and any unneeded hardware yet still nothing but a second of spin life. I have conducted the paper clip test as well, it works with the light load of the case fan. Which means the PSU isn't totally dead and still turns on when shorted but when connected to the mother board it flops. However, this oddness occured, when the cords are moved a certain way in the 24pin ATX the case fans and pc come to life for brief splits then die, then come on then die. Recap: - CMOS Battery removed and put back in, still fails to start. - CPU Power connector and ATX are in, still fails to start. - Passed paper clip test. - Old PSU will start all hardware. - New Psu will not start MoBo alone with no hardware. Questions: - Is there a faulty wire in the ATX? -Is the new PSU just bad and can't handle the load of the MoBo? -Is the new PSU possibly detecting a short and my old PSU didn't? -Can it still be a switch issue even though my old PSU can turn on my PC with all hardware attached? -Am I just that fail that I am missing something? -Solutions?
