blah97 Posted October 12, 2013 Share Posted October 12, 2013 HI, I just bought a Corsair CX750 PSU. The pc runs fine but I can hear a very faint noise coming from the PSU. When I start a game up like WoW, the noise gets greater, (sounds like a sizzle but gets loud) and waves start appearing on my screen. I tried to play CS Global Offensive, but the PC shut down the second it went on to a level. I'm guessing it's the PSU just because of the loud noises. They happen exactly when something appears on the screen. Like when you jump into a game, the noise get louder then dissipates when you go back to desktop. My part number is CP-9020015. I tried the official support form but it wouldn't take this part number, so I couldn't proceed any further. Any help would be great, thank's loads. Things I've tried so far are. Checking all the connections. Taking the mobo out and doing a complete reinstall. Taking the PSU out of the case and running it. Changing some of the Bios specs. ( I'm not good at that though) Removing all components apart from the PSU and SDD to boot the system. I can still hear the noise but very faint. Can't put it under load because I took the graphics card out. Link to comment Share on other sites More sharing options...
