MK2 Posted November 12, 2010 Share Posted November 12, 2010 I just bought and installed the AX1200 and I have a couple of problems with the PSU. It makes a constant buzzing noise wich looks like if it's the fan. I have to switch the PSU off/on first before I can start the pc with the button on the case. The 5 volt line seems a bit low at 4.8 volt measured in the bios and with HWmonitor. I had the HX850 before and had none of those problems. Because I have overclocked my CPU all power saving futures are switched off. Is there anything I can try/check and if not is it possible to get an advanced RMA?
