I never buy cheap PSUs, the Be Quiet Straight Power 10 CM is a pretty good unit if i am not totally wrong (second highest tier of Be Quiet PSUs).and never stressed it, mostly gaming with a i5 3570 and 1080ti/2070super.
My next PSU will be an A Tier unit for sure, problem is,i don't know which one, favorite is still the 750/850 RMx (dunno if 2018 or 2021 revision).
Tomorrow i will build a new PC with a new plattform (5800X + 32GB DDR4) in a different chassis, only the GPU (since you can't buy a new one for reasonable prices), soundcard and the PSU will stay.
Would use it a few more months until the PSU prices in my region (germany) settle a bit more (downward trend atm.) and i finally decide which unit i want to buy lol.
Will check the PSU for bloated stuff inside and remove the dust (without opening it) and after i installed it in the new chassis, will also check if the fan is doing some weird noises.
However, it should still be relatively safe to operate, or not?
If you think how long some pre built PCs cheap PSUs are beeing used and nothing happened...
Maybe @jonnyGURU can leave a few words in here?
