11.8 -12v
12.0 +12v
5.0 - 5.1 5VSB (constantly fluctuates between 5 and 5.1, all other readings are constant, is this an issue?)
260ms PG
5.1 +5v
12.0 +12v
3.3 +3.3v

This is my first time using a tester but the numbers seem fine, I was just concered about the fluctuating 5VSB. I've been having weird hitching and frame loss in more demanding games, which kicks in after 1 - 3 hours usually.
 
What PSU do you have? A PSU tester tests the power supply when the PC is idle not when under load. I would start a gaming session while having a program like Hardware monitor on which will display fluctuations when your components are under load. In addition, it will show you if any parts CPU or GPU are running too hot which might cause them to run at a lower speeds to cope with the heat.
 
Under 60c on both, so it's not heat. I've been troubleshooting this issue for a week now, I have done all the basics and then some, which is why I bought the PSU tester as a last hope, I was hoping it would show an issue so at least I'd know what the problem is as I'm sick of trying to fix it.

The 5v fluctuating won't be an issue - its probably at something like 5.09 but with only 1 decimal place to display it will swap between .0 and .1 due to margin of error.
 
Those PSU readings are perfectly fine.. Healthy power supply...

FPS loss after a good gaming session? hmm,
Main thing id look at, is it throttling?
CPU or GPU???
check GPU usage under load as apposed to CPU usage..
see if we can cross a very small bottleneck off the list..
 
The PSU tester won't show any issues when under load. Those figures however do look fine.

I'm assuming you've tried running everything at stock speeds? By framerate hitching what exactly is happening? Is it a loss in FPS until you reboot or stuttering?
