psteph Posted February 7, 2013 Share Posted February 7, 2013 Hi there, I've just switched from an old Enermax power supply to a Corsair AX760. EIST, ErP, EPU are disabled by default. I tried disabling C1E and Speedstep but this unit won't stop whining even when the computer is powered off. The noise usually goes away 30 seconds after switching the PSU off (I guess when the capacitors are discharged); It won't when the computer is powered off and the switch is not set to "0". I tested it on another motherboard but still no luck. Switching from Hybrid to Normal mode did not resolve it either. I used to own a HX620W that would not stop whining unless I turn off C1E. I had to get rid of it as a replacement yielded the same results. Before posting I read similar posts (AX860 included) and wonders what the best move is. Should I RMA it, wait for a potential recall (or whatever Corsair comes up with) or eventually swap it for an AX760i which I heard has no coil whine ? Kind regards, Stéphane.
