Hey all, I just barely got my new R9 390 but I seem to be having issues, so I had a 700W XtremeGear Power supply, it seemed to power the pc alright but I wanted to make sure it had extra so I said hey why not upgrade?!
So today I bought a new PSU, CX850M 850W and I got it cheap since it was on sale at Best Buy. Well since installing it I seem to have major performance issues with my GPU, it's at 100% use on Afterburner all the time since, seems to be loading textures a lot slower, but also under load I hear a Coil Whine it sounds like, almost a ticking squealing noise right? I can't tell for sure which part it's coming from but it wasn't there nor was I having issues with my GPU before the power supply swap...
1) Basically, can a faulty PSU cause performance drop and usage spikes in your GPU?
2)I keep hearing that coil whine is common in new Corsair PSU's amongst others, should I give it time to see if it clears up or get a new one?
3) Should I just reinstall my old PSU and return this one?
4) Is the coil whine just simply coming from my GPU? Is my GPU Faulty?
I will point out that cpu usage is at 37-45% any given time while gaming like on ark, and the ram is also extremely low, no high temperatures at all. Very stable. Just my GPU started maxing out constantly now I lag like crazy. Also, whenever I hit a lag spike the coil whine goes away for that split amount of time.
