Tech Addicts posted Ultra X-Finity and X-Pro 800 Watt Power Supply Review

Overall, the X-Finity and X-Pro (both offered at ~$200) offer excellent performance and sound characteristics. Both offer up to 800 Watts of power, which leaves plenty of headroom for today's computers. It is up to the user to choose whether they like the FlexForce cabling (X-Finity) or the standard mesh cabling (X-Pro). I enjoyed the AST, which allows for the power supplies fans / 3-pin fans to remain on, even when the computer is shut down. This can prolong the power supply and system components lifespan.
