PSU not giving enough power to CPU/Whole system, or faulty psu

Whats your PSU wattage?

<500watt on your rig is not a good idea

Well, we can't really go by voltage readings from a program, they're often wrong.

That's false.
The readings are totally off.

Hardware monitoring is inaccurate.

There is no way the PC would boot if the 5V was at 2.6V.


What PSU is this?

That's a PSU? Was thinking more along the lines of OP strung a bunch of batteries together with the fluctuations in power.

Again, program. Can't rely on those readings.

Until the OP responds, there's nothing we can do to help.

Agreed, but if the readings are accurate then there is the problem. Change PSU to something reliable with enough power to run the system.
