Hello, I had a question about some power supplies I bought. They all emit an odor that is overwhelming if in operation and no ventilation/ door closed.
It's not a really bad smell I mean you have to put your nose right by the exhaust or right inside the PSU. I modded an aftermarket 120mm LED to 12v for all 3 so they would run cooler and look cool. Maybe they just need to be cleaned? I also oiled the bearings on all 3 and used some tape so not all the oil leaks out... not the most appealing tape job but you can't see it when installed.
The PSU's smell slightly like an electronics factory. They are stable and have 12.50v across the 12v and above 5v on the 5v, as well as above 3.3v on the 3.3v. Under load sure can droop that 12.50v to 11.47v though. Still remaining stable. It depends on at what overclock and temperature limit in the GPU is set for the smell to become quite bothersome. So I dial back the temperature limit until smell is not so noticeable. All 3 PSU's smell when at idle and the same at load, with too much load say a 290X it's quite smelly. So not using 290X, using RX 480 Polaris and it's 100x better.
Can you take a look and see if you see something and maybe if the caps are of low quality? Also if I could replace some that are dedicated to the 12v rail to reduce droop to almost none at all? I'm willing to repair these, as well as give them all a good bath! I think a good cleaning could help with the smell as well.
Thanks
