AlanCracknell Posted November 13, 2013 Share Posted November 13, 2013 My PC build is less than a year old an has been working fine until recently, where the PC has become troublesome to start. Once started the PC is completely stable until powered down, where the fun starts again. With the power switch on I do see power to the motherboard. I've performed a PSU test with a multi-meter. My first three attempts showed 5.13V from ATX24 pin 9 (+5VSB) but absolutely nothing on any other pin. The fourth test having turned the PSU off and on again several times resulted in all ATX pins showing correct voltage. Turning the PSU off and on, most of the time I hear nothing and I see only voltage only on pin 9 (+5VSB). Sometimes I hear a very quite click (quite relay?) and in these cases I see power on all the ATX pins. Is this a faulty PSU and should it be RMA'ed. I notice that Corsair no longer list the AX650 in the line up, and I've seen other posts with similar issues, is this a design problem? Link to comment Share on other sites More sharing options...
