psychov Posted July 12, 2014 Share Posted July 12, 2014 I appear to have an issue with my power supply. For no apparent reason the system power will turn off, then try to power up and turn off within a few seconds and on and off again in an indefinite loop. The only way to get the power supply to turn back on (and I can consistently confirm it is the power supply) is to wiggle one of the plugs at the PSU (main motherboard connector) the on off loop then stops instantly - the plug is very snug, and I am not moving the wires, just the plug! This issue is NOT generated by the motherboard not sensing a CPU fan as this is disabled in the bios. I am operating well within the limits of the PSU - 439W max output. This issue can happen at any time, even when the system is at idle @ 160w. Suggestions welcomed :) Link to comment Share on other sites More sharing options...
xclock Posted July 12, 2014 Share Posted July 12, 2014 if you mean 24pins connector ? then you just damage the motherboard connector traces while you force the plug to be in. you PSU is fine. take the mobo to your nearest pc shop to test. Link to comment Share on other sites More sharing options...

zorlan Posted July 13, 2014 Share Posted July 13, 2014 I bought the ax860 and I had a huge problem with getting the 12v pin to stay in. I had to use extreme force to finally get it to click. Everytime I would connect it and put the psu back in, it would slowly slip out...or wasn't properly connected. It drove me nuts. It was giving me the same problem that you have.

psychov Posted July 13, 2014 Author Share Posted July 13, 2014 Right, touched it, PC died. Unplugged everything from the PSU, and replugged everything with a "click" Lets see how I go....... :) Link to comment Share on other sites More sharing options...
