LitesX Posted January 25, 2013 Share Posted January 25, 2013 Hi guys, Recently put together a new build with the Corsair TX650 as the PSU. On power up of the system, the PC will not POST at all. The onboard fans CPU/Case fans all function. No signal is delivered to the monitor, whether from the onboard motherboard (Gigabyte Z77-D3H) output or the 7850 graphics card. I switched the power supply with an Antec 620W that I know to be working and the system booted and installed the operating system and all associated drivers etc with no issues. I also tried with a separate 700W Coolermaster PSU (GX750) and again the PC booted as normal. I switched the power supply back again to this Corsair 650W and once again, the PC completely failed to boot. I have since returned this part to the manufacturer (scan) and received a brand new replacement. This has the exact same issue, I know the PC is working because with the other PSU's it boots as normal, but with this Corsair nothing appears on screen at all, no beeps from the mobo, however again all Fans etc are running. Could somebody please help me with this situation? Is it a compatibility issue with the motherboard (Gigabyte Z77-D3H), or otherwise? I've always been a big fan of corsair (The Case/RAM are both corsair) but this is beginning to really frustrate! Thanks! Link to comment Share on other sites More sharing options...
