    • Great power supply
Needed a new power supply after upgrading my CPU and GPU. This is a power house for my use and runs near silent. If the fan on the other side of the room is on, I can't hear my tower, which sits on the desk.

Ahora temo que esta anormalidad pueda dañar otros componentes de mi computadora. ... show more
