Can somebody tell me if this system has enough power to operate properly or am I being scammed?

I ordered this PC 3 weeks ago then after a week I got constant crashes and restarts with code " kenler proccessor core 15 operating on low power for the last 71 seconds " and PC gives blue screen " forced to restart ". I was just playing video games like CS2 and Marcel Rivals.

Now I sent it back and there sending me a replacement of the same thing. Idk what I should do and what the issue is. Never had this happen before.
