With systems power consumption becoming more demanding than ever you need a power supply that will deliver the power your system needs. SLI setups, multiple hard drives, and more USB devices require a lot of power to keep them running. Ultra comes to the rescue with it's X-FinityT 800 Watt PSU w/ Active PFC. With Quad Rail, FlexForce Cables, & PFC (power factor correction) the X-Finity is one fine power supply.
