murple Posted October 9, 2008 Share Posted October 9, 2008 Hello, I purchased the Corsair 450VX some time ago after a recommendation on Silent PC Review. Ever since I replaced my old PSU with the 450VX I've noticed that I had to press the power button twice or trice before it actually powered on. This was nothing that really concerned me. But I also noticed that my computer "stuttered" in not too demanding applications, for example audio playback. I thought until now that this was a software problem. But when I googled a bit it was suggested that perhaps it was a problem with the PSU. I checked the voltage values the diagnostics program EVEREST reported that the +5 V rail was only at 4.62 V. Now I have switched back to my old PSU, a Chieftec 360 W and now the +5 V rail reads 4.84 V according to EVEREST. The computer now also feels more responsive in general. I also noticed that my Chieftec 360 W can supply 30A on the +5 V rail where the Corsair 450VX only supplies 20A. The rest of my computer specification is written in my profile. This is what EVEREST outputs: Corsair 450VX Voltage Values CPU Core 1.63 V Aux 1.63 V +3.3 V 3.23 V +5 V 4.62 V +12 V 12.48 V -12 V -12.40 V -5 V -4.70 V Chieftec 360W Voltage Values CPU Core 1.63 V Aux 1.63 V +3.3 V 3.36 V +5 V 4.84 V +12 V 12.42 V -12 V -12.33 V -5 V -4.67 V I have also measured the +5 V voltage on the molex connectors but since I only have a analog multimeter it is hard to give exact readouts but I can anyways conclude that the voltage is higher with my old PSU. Is my PSU defective or just too weak to supply power on the +5 V rail on my system? Sincerely, Oscar Link to comment Share on other sites More sharing options...
