The Ultra X-Finity™ 500 Watt PSU w/ Active PFC (MSRP $119.99) appears to be exactly what one would look for in a power supply of this energy rating. First, it is in an attractive enclosure of black brushed aluminum, with well fitting seems, and strong-looking materials. It is also very heavy – lots of circuitry as work here. The cables are what Ultra calls, FlexForce: They are designed to make routing and space-management better inside your case. They are an attractive black and silver scheme, and much more pleasant to use than the standard red-black-black-yellow cables. Of particular interest is the huge 12cm fan, which spins relatively slowly, and is very quiet. Yes, I would certainly be proud to show off this power supply. But does it perform? Here are the specifications direct from Ultra’s web site:
Specially designed for demanding, high end gaming systems, the X-Finity 2G supplies up to 37A to the 12V rail. The 2G also features “After Spin Technology” to help quiet the system and aid in prolonging the life of your components. Connectors for chassis fans are thermostatically controlled; RPM’s are reduced when temperatures inside the case are low. PSU, chassis and CPU fan connectors remain spinning several minutes after the PC is powered down allowing the system to gradually cool down after use. The incomparable FlexForce cables are dressed in a great looking titanium silver finish. Specially engineered cable design promotes easy cable management and 30% better airflow than ordinary cables by easily routing cable under the motherboard, behind drive bays… anywhere that gets typically unsightly power supply cables out of the way of airflow. 20/24-pin motherboard connection. 4-pin Molex connectors. 4-pin floppy power connectors. PCI Express, SATA, 4-pin and 8-pin EPS connectors. Versatile. Dependable. Affordable. The X-Finity FlexForce ATX power supply.
