1.3625V isn't the maximum safe core voltage, but instead it's the maximum end of the VID Voltage Range. The VID Voltage Range is the range of voltages that a motherboard can use when the vCore is set to Auto. However, this doesn't mean that 1.3625V is the maximum safe core voltage; the actual maximum is 1.45V.

So, 1.41V 24/7 is basically fine.

Regarding the voltage differences:
  • The voltage you see in Windows (like CPU-Z) is the actual voltage that is running through the CPU.
  • The voltage you see while idling in Windows is the result of vDrop.
  • The voltage you see while putting load on the CPU in Windows is the result of vDroop.
  • The voltage you see in the BIOS is the result of a very slight vDrop and vDroop because there is a small load on the CPU while you're in the BIOS.

Anyway, I personally don't know of any way to find out if the PSU is indeed the culprit, but the eXtreme Power is known to be a low quality to mediocre PSU at best (that is, for overclocking).

Thanks TwoCables... I stand corrected

Now I just wish I could find that Intel PDF that shows it. :/
