Sudoeste Posted October 4, 2013 Share Posted October 4, 2013 I have a tx750 (it's the third one i get, already rma'd 2 times) that for about 6 months was sitting unopenned on it's package. Earlier this week I opened it, exchanged my "temporary" grimtec for the TX and started the computer. A few minutes later I noticed the coil whine that I attributed to the board's VRMs. But as the noise was really annoying I opened the case and tried to search the correct location of the noise. To my surprise the noise was clearly coming from the PSU and not the motherboard. Everytime I move the mouse, the PSU starts whining. If I download anything via the onboard ethernet card, whine whine whine. I have an Asus m5a97 r2.0 (uefi bios). Even moving the mouse in BIOS with everything disconnected besides cpu, ram (also corsair) and every mouse I could find starts the whine. I stop moving the mouse the whine stops. From what i've read here in the forum this appears to be a common problem, so what is not working? QC ? Link to comment Share on other sites More sharing options...
