PC Randomly shuts down after GPU upgrade

I just got myself a new MSI GTX 1070 a few days ago and I installed it in my PC. It's an upgrade from my MSI GTX 760.

The problem is that whenever my PC gets under some load: Benchmarks or Gaming for about an hour it will just Turn off all of a sudden almost like somebody pulled the plug and then It start back up again immediatly.
I monitored my temps already, noting crazy going on there (everything stays below 62 degrees Celcius).

These are my specs:
CPU i7-4770
GPU MSI Gaming X GTX 1070
Ram 8gb DDR3-1333Mhz
Motherboard Gigabyte GA-Z87-HD3
PSU Corsair CX750M

If somebody could help me identify the problem that would be great because I can't seem to figure it out anymore.

  1. Sounds like power problem. How long have you been using your PSU?

    The PSU has been there for around 3 years now.
  3. Have you had this problem when you were still using your 760?

    No I started happening after I installed the GTX 1070.. I also just double checked everything already and all connectors are where they should be and fit perfectly.
  5. Hmm ... that's weird. 760 and 1070's TDP's are not that far apart so you should be fine. Have you tried the 1070 on a different PC?
