A PSU doesn't have an effect on a systems performance.
It is just to provide stable, clean, power.

What may have happened in your case is you moved cables when you installed a new PSU fixing your issue.

You sure?
There are serveral energy groups in the fuse box. Suppose you have multiple machine hefty machines active at the same time within the same group, this can effect power draw and in the end effect performance.


I am positive.
It will either provide sufficient clean power or your PC will crash.
Components also have their own power regulation in order to clean up and buffer some of the energy flow.

On the flip side, majority of PSU's also have multiple technologies such as over and under-current protection, you can guess what that does.
It does not affect the processing rate of your components, if the PSU isn't up to the task, your entire PC will simply crash as most PSU's these days run off a single shared 12v rail.

Lets for example, say you have a 300w PSU with the standard array of proction technologies with a 250w GPU and a 100w CPU... Under normal circumstances everything would be humming along perfectly fine with nary of an issue, but fire up a game that engages the GPU, suddenly power draw will increase by 250w.

What happens there is the GPU isn't going to crash, the entire system is, because where the GPU gets it's power from and where the CPU gets it's power from is from the exact same 12v rail, if the PSU can't handle it, it shuts down, bringing the entire system with it.

Now, the Op's entire PC isn't crashing, thus by extension the power delivery is not the problem.
Those who say "Buy a new PSU" when there is a performance issue, really do more damage than good as more often than not, it's not the problem at hand.
