Power Supply Unit

Silverstone ST50EF Plus (500 W)

energy efficient components

This power supply isn’t capable of supporting multi-GPU setups, as the 500 W maximum power output won’t suffice. However, this is one of the most efficient models in the mainstream segment, and we’ve had good experiences with it. We also used this for the $500 Gaming PC 2007 Edition.
