Brand new PSU (Corsair RMx 750W) smell?

PaulM · 13 Sep 2021 at 21:06

I just bought a Corsair RMx 750W (it's the 2018 version, not the 2021 version, but brand new). Before even turning it on I noticed it smelt but didn't think much of it, just thought it was because it was new... but I've had it on for 6 hours now and there's still a strong chemical smell coming from it.

I've only had a couple of PSUs before, this was replacing a 12 year old one, but I don't remember any of them smelling like this even when brand new. Searching around seems to give conflicting info whether it's normal or not.

Has anyone else had this? Don't know whether I should hope it goes away after a few days or just RMA it.

Thanks

Thanks for the replies, it's been running nearly 36 hours now, the smell is still there but it seems to be slightly better than yesterday. I'll give it a week and if it doesn't go away I'll RMA it.

I couldn't see anything leaking but without taking it apart I can only see about half of the capacitors. This afternoon I left a benchmark loop running for a few hours to get the PSU fan spinning, now the smell seems a bit better so hopefully it's ok.

Been running for over a week now and the smell is still stinking out the room so going to RMA it

Thanks for the advice, picked up a replacement RMx750 and this one doesn't smell so I guess the other one was faulty in some way. Another positive is the replacement also completely eliminated the coil whine coming from my 3070, first time in 12 years I've had a PSU/GPU combination that doesn't have annoying coil whine!
