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.

Thanks in advance for any/all advice!

The VS lineup isn't really that great, so those issues might be related to the PSU being unable to handle the system raw properly.

I'd probably get one of these units. Full modular (all cables can be detached, for ease of building), Gold efficiency (less energy being wasted) and solid internals (what matters most) make these the prime picks

Do you think a 650w would be enough with the fact I upgraded my GPU & RAM recently? I thought maybe I would step up towards 800-850w, but if I don't need to I wouldn't mind. Wouldn't hurt the pocket as much.

RealHardTechX's PSU guide says you could get away with 600W, so 650W is plenty

With the GPU and RAM upgrades, you should be fine with 650W (800-850W is too much)

Thank you very much sir! I thought I was doing something wrong when I was using those PSU calculators & getting 650w, glad to see I wasn't lol

PSU calculators generally aren’t that all accurate, so if that’s anything to come by.

PCPP says 419 Watts (estimated)

The above RIG will definitely not consume more than that (worse case scenario.)

So 650 watt is out of the question.

However keep n mind there is a difference between...

The computer will consume 650 Watts vs a recommended PSU for the above build.

Because the above computer will never come close to that 650 Watt number, but a recommendation for a 650 Watt unit seems logical. :)

jake2917 submitter 1 point 2 months ago

Okay so to simply put it: 650w would be good..? Lol I read that twice & got lost both times.

I am running a 650w right now but it's a very very cheap PS. So what I want to do is pick up something 80+ Gold @ 650w & I should be solid eh?
