[SOLVED] GPU crash and burning plastic smell coming from PSU

[noxus_1o1]

I recently bought a Nvidia GTX 970 and when I tried gaming on it it would crash to a blank colour screen, I managed to fix this by underclocking it. After I tried playing dirt rally 2.0 on ultra settings and it performed really well but there was a burning plastic smell coming from the PSU (I could be wrong and it was coming from the GPU but I am fairly certain that it was coming from the power supply). Then the screen went black and I could still hear the game, this could just be the cable though.

the PSU is low quality and most likely the problem but I just want to confirm before I go out buying lots of computer hardware

CPU: Ryzen 5 3600
HDD: Toshiba P300 2TB
Motherboard: Gygabyte a320m-s2h
RAM: 8GB DDR4


I tried using my old GPU and there was still some smell coming from the PSU
I was also using SATA to 6-pin adapters I should get a new power supply anyway
also does not crash with my old gpu

Replace that PSU ASAP. An 18 pound PSU? I wouldn't dare to think powering a CPU like that with a sub 20 pound PSU. Never trust anything that cheap. Also, when you smell burning/melting plastic, do yourself a favor and stop what you're doing. That's a good sign to stop what you're doing.

Replace the PSU with at least a known brand, an 80 Plus White label for all I care, but don't fool yourself like that again, dude..

Please don't feel like I'm attacking you, but it hurts my eyes to read what's written above..

Ouch! That's not even a 300W PSU. And when a "500W" PSU is only really a 264W in a modern sense, the innards are going to be equally a horror show. Get a quality PSU -- we keep a curated tier list in the power supply forum -- and cross your fingers that this garbage didn't fry the GTX 970. One of the most expensive things in PC building is a cheap PSU.

Great! Be careful of junk PSUs in the future. We want as many PC stories to have happy endings as possible!

hahahahahaha, I always cringe when I read about people smelling something burning coming from a PC, and I fully agree on the "I'm not attacking you" part, it's just that the smell = NOT GOOD

Glad you sorted it out! Good PSU's ONLY from here on bud!
