620HX Voltage Question

post #1 of 31
Thread Starter 
I recently bought a 620HX to replace my Raidmax PSU. When I put it in and turned it on, I noticed HWmonitor said that the +5v was reading 4.89v.

Is this normal for the 620HX? My Raidmax gave me 5v or a little bit more.

Its within acceptable ranges, but also never rely on the bios or software for voltage readings. If you are concerned always test with a multi meter, this is the only reliable way for accurate voltage testing.

Exactly. Software is notorious for being considerably inaccurate at reading PSU voltage levels.

You could try checking in your BIOS. While definitely not as accurate as using a voltmeter, in my experience they seem to be relatively close readings.

The BIOS is still read from the same sensor as software which is too far from the PSU to accurately measure the voltages the PSU is producing.

It may be read from the same sensor, but quite often software has an inability to read the sensors correctly and report the same numbers as in the BIOS.

I've seen programs like Everest and Speedfan report voltages nowhere near the BIOS readings. The BIOS, in my experience, is fairly accurate. But like I said before, it's not always 100% correct.

Software gets it's readings from the same chip the BIOS does, so to say readings from the BIOS would be more accurate would be a falsehood.

Thats why if you want to save your CPU some lifetime it's good to keep it a little below 1.5 since BIOS can be a off a few notches.
