Ultra X3 Is Prepped For Power

The X3 1000W PSU boasts a kilowatt of power output and 85 percent energy efficiency at typical loads. The PSU features full-range active PFC.

Test Center engineers were pleas-antly surprised at how quiet the power unit turned out to be while performing on low to medium loads. Even under high loads, the noise remained acceptable. The thermostatically controlled 135mm ball-bearing fan draws air in through the bottom of the power supply. The exhaust air exits through a honeycomb grill located on the back of the unit, keeping the unit cool.

The X3 ships with an assortment of modular FlexForce cables since the power unit's modular interface allows builders to plug in only the cables applicable to that particular machine. The X3 has connectors for Molex, SATA power and PCI-E. Engineers unpacked 19 cables and noted that some of the connectors were labeled to minimize confusion. For example, the 24-pin motherboard connector clearly differentiates the two connectors with "To Motherboard" and "To Power Supply" labels. Two cables with eight-pin PCI-E connectors are included in the box for machines using 300W graphics cards.

The X3's user manual outlines the 10-step installation with images showing where the cables need to be plugged in.

Engineers also noted the X3 1000W PSU is larger than the standard power supply, measuring 5.9 x 3.4 x 7.9 inches. In general, power supplies measure 5.5 inches in length. System builders will need to verify the available space inside the case beforehand.

The X3 1000W PSU comes with a lifetime warranty.
