Pc losing power

[AA04]

I just finished my new PC (https://pcpartpicker.com/list/GbqkNN)

It boots fine and starts up all my programs but as soon as I try to launch something else it instantly shuts down (all fans and lights turn off)

 

I thought this was an issue of not having enough power so I upgraded from 450w to 750 and nothing changed. I know all my parts work fine except for the graphics card as I just got it used, but it seems like a graphics issue shouldn't shut down the whole PC. Any suggestions?

After more investigation, I can browse the web fine and stream video, it's just as soon as I open a game or a benchmark that it turns off

Do you have another GPU to test with

Is there a blue screen?

My 950 worked fine with the same parts except a weaker power supply, no blue screen just straight power loss

Is this the problem, or is that just an offshoot suggestion?

So if I got a grey you think the system would work?
