i5 4440
8GB ram
ssd 120 Kingston
PSU corsair 650

It doesn't work that way. A PSU cannot "run out of power" and if a PSU was giving DC, then not giving DC, it would just not work plain-out, complete system error would occur. A power supply cannot run out of power.

I never said a PSU can "run out of power"...of course that is not how it works. But a poor quality PSU can give INCONSISTENT power. This on the other hand CAN, and DOES, happen.

Power is more than just Wattage...there are Volts, Amps, Ohms, etc. A poor quality PSU may not handle all aspects of power the same same. A poor quality PSU has less Amps on the +12V rail, but still have the same Wattage rating. Also, a poorly made PSU has more resistance (Ohms) which would give inconsistent power at times and effect the Amps given on the +12V rail.

Think of a poor quality PSU like a poor driver to a car. If the poor driver does not keep a steady pressure on the gas pedal, the power will fluctuate, regardless if the car (PSU in this example) is a Ferrari or Prius. Hence causing issues on speed and performance of the vehicle (GPU in this example).

You did not define what you mean by inconsistent power. I appreciate your explanations, but I have been studying power supply units for many months and am well familiar with electricity.

Inconsistent power. Not sure what you mean by that. Power is energy flow. There can be consistent power and it can cause troubles. If the 12V rail is at 11.2V and current is a constant value, power is consistent, but it causes problems. There can be inconsistent power that is safe for hardware, too. Any time load changes, so does current and voltage, which means energy flow rate changes. When something changes, consistency is lost.

Unstable voltage is more the correct terminology on the issue. When you say inconsistent power, it is too broad to understand what you are trying to convey.

@turkey3_scratch

I agree with what you are saying; though, generally when someone posts here they are not that aware and knowledgeable with the inner workings of a PSU...so I summarize it with "inconsistent".

Never-the-Less, do we agree the PSU is the main suspect in this case?

I don't intend to sound rash at all, I just like to be consistent with terminology. I do not personally think it's the power supply; I think it's a software issue, and if he runs a stress test it'll help to see if GPU usage is at 100% during it.

I think this is a problem with the PSU, maybe resistance in the PSU is poor which disrupt the energy flow. changing to any other PSU you might have in the house for just testing should see if this is the problem.

what do you mean software? in the gpu? or in my comp?
can upgrade bios to gpu help improve this problem?
