GeForce 1050TI restartat problem when gaming

[emanueltritean]

I have a GForce 1050ti and a power source https://www.beezmall.com/productdetail/Segotep-Nuclear-Power-Aircraft-Carrier-H9-Plus-520W-Semi-Module-True-Power-PSU_8dfd8f02-8932-47ae-a1aa-23eaf101d037

When I'm gaming my PC shuts down from time to time. It boots up back normaly, no problems.

Do you think that the power source is the problem?
Should I buy another one?

I bought this one at the end of last year.

Also when I'm gaming in Task Manager at the GPU I have the 3D monitor to 100%.
When I alt+tab it gets back to normal. Do I need to worry about it?

Thank you for your help.

Usually when using the full power of the video card, if the computer "reboots without a blue screen of death (BSOD)" error, the problem in general is either the power supply or the video card.

Do I have a way to check what exactly is the problem? Both of these components I bought middle of last year so It's a little frustrating

Look at your gpu temp but i dont think it is problem. I think your problem is psu. This psu doesnt look very reliable. It says efficiency is 79 so that means it can deliver like 410w. What are other components you have?Btw i dont think this psu has 79% efficiency on more than 50 percent load
