I bought a prebuilt awhile back & have since upgraded my GPU, RAM & recently went from a 1080p 144hz monitor to a 1440p 120hz. I went from a GTX 1060 6gb to a GTX 1080ti FTW3 & very basic 16gbs of RAM (3000) to G.Skill Trident RGB 3200. I have a corsair VS650w PSU currently & that was always fine but with my added parts I think I'm pushing too much power for the PSU to handle. I might be wrong; I know very little when it comes to this. I looked up my current PSU & found out its very cheap/low end. My RAM isn't able to get to 3200hz like its supposed to even after tweaking it in the bios & it makes me wonder if that is because the voltage going to the RAM isn't enough.
Spec List: i7-8700 3.2GHz, ASUS Prime Z370-P motherboard, GTX 1080ti FTW3, 16gbs Trident G.Skill DDR4-3200, 250gb SSD M.2, 2tb Seagate.
I also have a 120mm liquid CPU cooler, x6 Corsair LL series RGB fans & a RGB light strip (figured I'd include these because I'm asking about my power supply).
I also am experiencing some black screen after awhile of gaming. I will load into a match or an area & the screen will go black, then come back for 2-3sec then go black again a couple of times. Not sure if that has anything to do with the PSU but figured I'd add that.
If you do think it is my PSU like I do, do you have any suggestions on an upgrade? I was thinking something around 850w 80+ Gold or better, but when I look at PSU on NewEgg I get confused because there are so many different models. I've never looked up a PSU, is it confusing? Seems like a lot of different cords.
