beaksdale Posted January 26, 2013 Share Posted January 26, 2013 Hi, I just brought and fitted a Corsair HX750 but it isn't booting up the system. The light on the motherboard comes on to confirm that there is power going to it but when I try and turn it on nothing happens except a faint click that sounds like it is coming from around the CPU (only the first time after turning the PSU on then after that nothing happens when trying to turn the PC on and off). I checked that I had done all all of the wiring correctly and that seemed ok. I then took the PC apart to check that I hadn't damaged anything and that seemed ok. Next I tried refitting the old PSU that I was replacing back in and the system powered up so I put the HX750 back into the PC and tried the paperclip test and the fans came on so finally I tried resetting the CMOS and still the system will not power up with the HX750. Does anyone know if it is a fault with the PSU and I just need to replace it, if there is a problem with my motherboard or a compatibility issue with the PSU and my motherboard? Or does anyone have any suggestions as to what I can try next? Link to comment Share on other sites More sharing options...
