Games crash probably because of power supply, need confirmation

So, recently I upgraded my computer (well, the only thing I didnt change was the hard drive). I thought it was alright - I could play the witcher 3, GTA V, DOOM, Watch Dogs 2 on the settings suggested by Geforce Experience, but some time ago the games started crashing after 10 - 60 minutes of gameplay, depending on the game. The games only stop crashing on the lowest/medium settings. I have a theory, that it might be because of the power supply I have, althogh ive never seen crashes caused by that, and im not sure if it is it nor do I want to buy a new PSU for no reason. So basically what happens is i play a game on high settings with stable 60 fps, suddenly BOOM game freezes for around 5 sec and closes (used to show a windows message "Program *game name* stopped working, doesn't do that anymore). One strange thing is that The Surge, Dark Souls and DOOM dont crash so... that kinda doesnt make any sense to me

I have a GeForce GTX 1070 Ti


Also one problem is i dont remember the exact voltage of my PSU, is there any way to check it? Without disassembling the computer, of course

I tired FurMark and Prime95, everything worked fine, my psu is 750 V... I have no idea what it can be. I checked the drivers, they're up to date

Hey, s'ok, I'm just setting ya straight so the less kind don't do it while laughing at you.

I haven't heard anything bad about OCZ PSUs. What part of the world are you in? Is your house power 120 or 240? I ask because the model of your PSU includes "EU" and I'm wondering if maybe it's looking for the wrong input voltage.
