Power Supply

of the GPUs you install. If you are going to SLI two graphics cards, you are
going to require more power. As a rule, for one GPU you need a minimum of
a 300 W power supply. If you have two GPUs in an SLI configuration, you
will need a minimum of a 500 W power supply. If you have three GPUs in an
SLI configuration, you will need a minimum of a 1000 W power supply. To
