+5V reading?

[BTK]

I have a high quality power supply. Corsair HX520W. I am concerned my +5V is low or is it? I have no multi-meter to check right now and this is idle.

You cannot trust "software" measurements at all.
Not even as a "reference point".

Only a multimeter can show you the "real" voltage.

Your PSU is more than adequate for your system, and unless it's faulty it should be handling it just fine.

ok thing is ive NEVER had any crashing or random shutdowns and i just noticed this

The number is meaningless, disregard it.

5% is pretty much a commonality when it comes to voltage tolerances. It would be wise to use a multimeter to see exactly what the rail is at.

Then don't worry about it.

If the PC was unstable, you could use the software to give you a vague idea of the source of the problem, but since software is known to be off for valid reasons and the PC is stable, you should just ignore it.
