PSU Buzzing

[Jason22]

Hello! I'm just posting about a question I have about my new PSU I installed a couple days ago. I noticed a buzzing noise coming from the PSU, even when the computer is off. The buzzing stays the same when I turn on my PC. The buzzing does get louder when I'm gaming. Is this coil whine? And should I worry about my PSU at all? I just don't want my PC to bite the dust again. I recently had a PSU die on me, and fortunately none of my parts died. My new PSU is a EVGA 750 G+ and my system specs are:

Ryzen 5 5600X

RYX 3070

32GB DDR4 RAM

B450-F GAMING II Motherboard

Here is a video of the buzzing.

its not harmful but annoying, i also had evga g6 with buzzing so i returned it, i have seasonic prime gx that its quiet on all loads, so you should look for seasonic/ be quiet/ corsair/ super flower psus.

no. this is exolained in every psu thread that mentions seasonic in some way.

Well its Seasonic, Seasonic in general has a lot of problems, and bad communication with othert people, for starters.

Old revisions (2017-2018) will shut off on some GPUs (970, 1080 ti, vega 64, Vega VII, 2080 ti). it'll will trigger the overcurrent protection, and will shut down immediately. This is likely due to the high transients the GPUs are known to put out

 

New revisions (2018-2019) have a bigger headroom, but aren't built for it and start to ripple at the loads where the PSU would shut down at with the older revisisions.

With that is focus known to be quite loud under load, has a staggering 200% opp on the 3.3v rail, but this isn't as concerning as the above mentioned problems.

 

So to sum up:

Seasonic Focus and Prime units in general have a lot of problems. Seasonic is bad at communicating so we do not know if they are fixed or not.

 

This also affect a lot of other psus based on priem and focus.

FWIW I have an EVGA G+ 750 as well, quiet so far but its only driving a 980 Classified and 3770K.

 

I also have a Prime PSU driving an Ampere GPU and a 5900X. No problems. Some say its just a fancy Focus

 

There are a few guys here who really do not like Seasonic.

 

I wonder why..

I'm glad that it's not harmful, I've just never heard a noise like that from a PSU and I was just worried.

Likely because they're overrated as hell and not even that fantastic objectively speaking.
