PSU Whining problem!!!!! Tags: Power Supplies Cases Components Last response: September 6, 2012 1:35 AM in Components Share lolollii September 6, 2012 12:41:42 AM I received this replacement 2nd PSU today from amazon, just connected it. EXACT same problem, so it's not the psu. Also worth adding I installed my rig into a new case this week (brought a new case, psu & ssd) The sound only occurs after the PC is shut down it seems. It's constant until the PSU is powered off. Here's a video, might wanna turn your sound up I also turn it off at the end, note the pitch change Any ideas? Cheers guys!
