Which power supply to choose for the assembly?

Question

Power Supply

Recently, when entering games, it began to reboot, and besides, sometimes a black bar appears on the side of the screen, I sin on the power supply. Maybe I haven't changed the thermal paste in a long time.
I can't tell you the exact name of the monitor and speakers.

We look at the requirement for nutrition vidyahi. We throw a bit on top. We look at the "80 PLUS" power supply and you're done.
