[SOLVED] Screen goes black and computer shuts off while gaming

[Massiveredboi]

So just today my computer(which is a prebuilt that I modified) has started randomly turning off when I play something like Rainbow 6 or Titanfall 2. The screen will also turn black and after a minute will then shut down the computer. It also happened once or twice when I wasn't playing a game but had stuff like steam and a movie open. I'm pretty sure that the crappy psu is to blame but I wanted to get a second opinion.

i5 4460s
2x8gb ddr3 1600mhz
2k monitor
1050ti
Some chinese psu

I'd like to also mention that I haven't been playing my games at 1440p but my desktop is at 1440p. I also have a moving 2k wallpaper. I also have been using this all for a year.

P.S I forgot to mention that it sometimes simply turns off without turning the screen black.

Sounds like the PSU indeed.
Can you link or post the make and model for it?

Alright, but real quick, is there anyway to test and make sure my psu is the issue?

It will be the PSU, cheap Chinese junk.

How to test if it's the PSU? Only reliable way is to buy a decent one!
Crappy one doesn't need testing -- no point. Whoever prebuilt your PC with that PSU should be ashamed of themselves.

Lol, bought off a chinese net cafe going out of business, so its kinda to be expected. I'm actually surprised it worked for as long as it did. Thanks anyways!
