Which is the correct 3.3V

[Mind2278]

Hello,

I recently switched from MSI to Asus motherboard, but I can't figure out which one is the correct 3.3V Voltage rail? Is it the "3VCC" or the "3VSB_ATX"? Because the last one mentioned is at max 3.4v, that is a little high if that's the 3.3v rail isnt it?

I hope anyone could help me out. Thank you.

the tolerance for the 3.3V is 5% (3.13V -3.46V) so it's ok. Also, keep in mind motherboard sensors aren't proper calibrated voltmeters. They are here for indication only and if you measured directly the 3.3V you might get a pretty different value.

Both voltages are correct and within acceptable range. The VSB is Standby Voltage.
