PC loses power

[pavel_kolarov]

I was not sure for the category, so i selected CPU's.
Here is my problem. I recently moved in a new apartment.My PC was working fully stable before. When i installed it here,everything worked fine too for the first day, i even played some games on it.Now it became acting extremely strange. As soon as the components are under load the computer loses power and turns off. All fans and led's stop and then it boots itself again and loads windows. I reseated all ram and cables, removed all overclocks and still nothing.i checked another threads and tried to disable automatic restart on error, but it didn't change anything. What could be the issue?please help.

Specs:
- Intel xeon x5650 @4ghz(4.3ghz turbo boost)
- Asus p6x58d-e
- Powercolor R9 380X pcs+ myst edition ~10% OC
- 2x8gb corsair vengeance lp ddr3 ram @ 1820mhz
- Seasonic M12II 750w 80+ bronze psu

Tried in a different power outlet already? It could be it,

Tried it, but didn't help.

Removing all of the dust hasn't changed a thing as well? Maybe when it was inside the box it accumulated more and now it's overheating.

Can you post the CPU and GPU temps while under load?

I periodically clean my PC from dust, so dust isn't a problem for sure. as i can see the temps are the same as before. Cpu is cooled by h80i v2 and reaches around 55 grad Celsius in games and 75 grad Celsius on stress test. Gpu gets a little bit hotter than it should, especially with the OC, but it wasn't a problem before. It reaches around 80 grad Celsius under load, even 85 after a few hours of gaming, but people always said its perfectly safe for R9.

Just played gta V for around 10 minutes to make sure the temps are as i said. The gpu didn't exceed 79 grad Celsius.
It looks like the temps are not the case. The pc was not in a box, it was wrapped with the transparent stretchy thing, while transported.
