first of all my specs:

OS: windows 10 64bit
mobo: asus Z170 A
CPU: intel i7 6700k,
GPU: asus geforce gtx 970 4gb strix
PSU: corsair CX600 v2 - 600w
networkadaptor: ASUS PCE-AC56

So I built my own pc a month ago and got everything to work. Now yesterday I was playing darksouls 3 and all of a sudden my pc shuts down. I tried to power it back up but it wouldn't do a thing. When I switched my PSU off and on and pressed the powerbutton, my fans would power up for about a fraction of a second but all would shut down again right after. When I press the powerbutton again it would not do a thing until I swithced it back off and on and then the same thing would happen. The power LED indicates my psu is good. So i figured it might be my GPU, the GPU led (which is on the GPU itself) indicated the GPU was fine. however when I would remove my GPU my pc would work fine, in fact I'm typing from the pc in question itself. I just want to be sure that it is my GPU that is not working or that perhaps my PSU lost power and can't handle the requiered power anymore when my gpu is connected. I don't know if it is relevant but I always would switch my psu off durning the night.

Any help would be greatly appreciated :)

A 600W Corsair PSU should handle your 970 without an issue. It's definitely either your PSU or GPU I would guess your GPU. You need to test your GPU in another system. If you do not have another system to test on if you can remember the date your PC switched off it might be worth checking through your event logs to try and find the cause of the problem.

I checked my logs and it tells me that I had critical event ID 41 Kernel-Power. So I looked it up and it said an underpowered or failing power supply may cause this behavior. But is this possible due to GPU failure then?

If that is the case and I have to get myself another one, what would you suggest as a PSU that is of good quality? :)
