Hello guys, I have tried a lot of things, I am absolutely sure thats it is not a temperature problem, I also have tried a stress test and everything was fine so i guess it is not either my cpu, ram  or gpu.
To help more it switches off when I open a game or a video on internet in about some seconds, when I do something lighter It does less or even not at all.
My system:
MOBO-MSI 990FX-A GD65
CPU   -FX 8350
GPU   -ASUS R9 290X MATRIX
PSU   -THERMALTAKE TOUGH POWER 850W 80PLUS GOLD

I also have done format 2 times so I guess its not problem in software.

Any ideas of what is causing the problem?

A 390X (rebranded 290X) has a max wattage of 750W, leaving 100W for the rest of your PC. Yikes.

No idea but that is what EVGA told me with my system

It will run fine on a 400w psu the wattage on the site is wrong

Thats that. If you need to get in touch chances are you can find someone that knows me that can get in touch.

@thekeemo corrected me. It doesn't rule out the PSU in terms of quality, though.

it could be a problem with anything, once it comes under stress then it forces shut down but the most obvious solution is a problem with the PSU

It could, but it sounds like a PSU problem. When something is wrong with a mobo, it tends to not boot or BSOD. Random shutoff is usually from a PSU.

When you say it "switches off", I take it you mean that it doesn't blue screen or anything it reboots as such, but goes to "off" instead of last power state and rebooting properly?

 

Can you tell us more info please:

 

How long you've had the PC? did you build it or was it a shop bought? etc etc, whatever you can think of the symptoms the PC has had.

 

At the moment to me sounds like an overheating problem, or maybe as others have said a problem with the PSU in some way.

Please quote my post, or put @paddy-stone if you want me to respond to you.

You can also try looking for "Kernel-Power" in Event Manager, and placing a speaker on the motherboard.

I am using the pc for 6 months and I am having this problem the last month, I built the computer on my own, also the problem started 1 day after the format, thats all I think that can help

Ever seen a fan connector? It's a tiny speaker that plugs into a special one of hose on your motherboard, although it's usually two pins over three or four. It beeps with codes you can Google or refer to us and get the answers for what each code means.

Does that processor have integrated graphics?
I'd say go back to bare-bones. Try without the GPU and see if it still shuts off.

Motherboard is faulty, if it was the PSU it would fail stress tests, I'm going to hazard a guess that the motherboard is shutting off. Are you overclocking the 8350 at all? is your ram set up correctly?
