Question How to clarify is power supply dying out?

[supersteff95]

So as a name of thread states how do i do it,cause i've been getting suspicious lately about it,because in few games that i play i used to have some weird stuff happen to me,like it could be working like good and like i get a massive stutter that lasts for 4-5 seconds,and it starts operating as it was prior to that,ive checked temps on gpu its good temps for msi rtx 3060 its cold,i've checked temps for my cpu its 5700 x3d its like 60ish on load while gaming,mobo is b550 gaming plus from msi it has latest bios on it,ram is 32gigs from kingston with 3200mhz,and the culprit of possible problem is 750w evga gq gold.i've got it from 1 guy like when i was puting whole pc together and he claimed that psu is under warranty back then when i was buying it(although its been fairly dusty i might be wrong but i think he used it in mining rig),but guy got baned from site where i bought it from so my warranty is nonexistent.I cant smell any odd smell from it like its burning,or whatever,but maybe something inside of it is falling apart and causing those symptoms?

So as a name of thread states how do i do it,

Take it to a test lab with thousands of dollars worth of programmable electronic loads, voltmeter/ammeter/power meter, oscilloscope, hot box or climatic chamber and run a full set of tests.

Alternatively, accept the fact you might have bought a "lemon" and invest in a brand new quality PSU from a reputable supplier, where you're more likely to get a valid warranty.

Personally, I'd stop using this PSU immediately, in case it goes bang and destroys your mobo or GPU. It's only a slight risk, but do you feel confident it will never happen?

The last thing I would buy used for a built is the PSU. It's the only part that can fry all the others if it's defective.
