PC loses power while gaming

[arendsoogg]

First of all, my specs:

CPU: I5 4690K

Cooler: Cooler Master Hyper 212 EVO

GPU: MSI RX 480 Gaming X 4G

Mobo: MSI Z97S SLI Krait Edition

PSU: Cooler Master G650M

2 harddisks and 1 ssd

OS: Windows 7 64 bit

 

So here's my problem: My pc will randomly lose power while gaming and power on a few seconds afer it lost power.

It just happend to me twice while playing euro truck simulator 2 multiplayer and has happened while playing battlefield 4.

 

I'm thinking it's a PSU issue but I'm not really sure, hence this post.

Same thing happened to me while playing Rust.

I narrowed it down to the PSU being chinesium (not really the case for you) and I also noticed it happened when the GPU power draw went over 120W (Sapphire RX480 Nitro+). Solved it by limiting FPS in Rust (to 62) and power limit on the GPU to 115W.

Changed my PSU and mobo since then, so I have no idea if that still works

It could really be the PSU, I think you should get a different PSU, and test it, only then we will know for sure.

I was thinking of doing that since I thought I didn't have any warranty, but it turns out that I still do have warranty so I don't really want to do that

I mean...you could just make use of your warranty then

Good to know, will monitor the gpu's power draw and see if that's the culprit. If so, I just need to replace the PSU?

PSU should handle the load just fine. Might be some sort of reminiscent power draw bug from the PCI-e. Or your PSU might just be getting old

I know it should handle just fine, that's what I think is so strange. But yeah, I think I have this PSU for about 2 years, so it might be getting old..

My pc lost power again while playing ets2mp, gpu power draw didn't even reach 100 watt according to msi afterburner.

 

Is there any way I to know for sure that my PSU is broken?

 

Oh and btw, I'm fairly certain that it's not my GPU since I recently got a replacement as my old R9 380 broke..

 

edit: just crashed again while playing farming simulator 17, get's fairly annoying crashing 3 times a day, which it usually doesn't..
