Hello everyone. I'm new to this forum so bear with me. I recently took apart my computer to install new case fans (vrm heatsink in the way in an itx build) and when it was all put back together I hit the switch and everything was fine. Temps reported by corsair link improved slightly. All was well when I attempted to launch overwatch and my rig hard shutdown completely with no error. I checked all the power plugs and I am 95% certain that the ac power cord was not pushed in all the way in the power supply. It turned right back on and I ran stress tests for about an hour and a half with no issues. At first I assumed it was the main game boost over clocks (6600k at 4.1 GHz) but those ran stable during the tests. Would there be any possible cause for the shutdown or do the stress tests rule those out? I ran occt for 10 minutes and firestrike extreme for a little over an hour. I'm relatively new to benchmarking overclocking and forums so I'm sure I left out a ton of Important information. Thank you all for your input.

MSI z170i gaming pro ac
Intel i5 6600k @ 4.1 GHz
EVGA GeForce GTX 1080 FTW DT Gaming ACX 3.0
EVGA 750 watt semi-modular power supply.

2 days and no issues just got a little worried I'm living in a dorm and would be out of luck if I didn't have a working desktop. Everything else seems to be running fine thank you for the responses

Everything passed and all seemed good but I have discovered that the computer now will shut down as if I shut it down through windows when it is bumped or moved. Is this more evidence of a loos connection to the power supply? I've thoroughly checked both 8 and 24 pin connectors and they are both clipped in securely. Not quite sure what to think as I am fairly certain nothing is wrong with the card cpu or Mobo. The computer runs fine under load.
