Question about Gigabyte GeForce GTX 1050 Ti OC

Generally, a 300~350W power supply is recommended. The graphics card itself requires about 75W. From this point of view, it should not be a problem. The PC would then primarily only crash when you put the system under load (e.g. games).

As Inematov wrote, I would check what error messages are there after a crash. The Event Viewer is not very easy to interpret.

A simpler possibility would be the reliability monitoring (see link). This makes the Event Viewer a bit clearer.

It depends on what else you have installed, especially which CPU?
Also check the Windows event viewer to see if there is a message there, and if so, what it says.
