humhorse Posted August 4, 2007 Share Posted August 4, 2007 Hi, I'm a little concerned by the voltage readings on my new HX 620W PSU. These readings are taken from within the BIOS, and are almost exactly matched by Asus PC Probe with the system at idle. +3.3V @ 3.25V +5.0V @ 4.78V +12.0V @ 11.65V The one that concerns me most is the 5V rail, as it's dangerously close to what's generally perceived as the 5% safety threshold (4.75V) Is this something to be concerned about, or is this normal?

EliteKiller Posted August 6, 2007 Share Posted August 6, 2007 Never rely on the bios or software voltage readings. Purchase a <$30 DMM from Sears, Radio Shack, Lowe's, etc. and test the positive rails. If you don't want to keep the DMM you could always return it for a refund.

Corsair Employees RAM GUY Posted August 9, 2007 Corsair Employees Share Posted August 9, 2007 EliteKiller is correct, the BIOS readings are not 100% accurate and a DMM would be the best way to test the PSU. As long as the readings are within 5% there should be nothing to worry about. Link to comment Share on other sites More sharing options...
