Specifications, Availability and Pricing

$249.99 is the MSRP. However, you can pick one up for around $200 U.S. these days, still placing it above other 850w units; some of which also feature modular design.

With that said, $200 seems a bit pricey and compared to its competition, it is. But in most cases you get what you pay for and this power supply is no exception.

With your hard earned money, Ultra intends to provide you with a product that will not only last, but protect your overall investment in your PC. The first feature to do this is short circuit protection; the second being thermal overload. These features in conjunction with a UPS are a great defense from dirty power.

 

This particular unit has received the 80 Plus Silver certification with claimed efficiency rates as follows: 85.58% efficiency @ 20% load; 89.10% efficiency @ 50% load and 86.51% efficiency @ 100% load. It had almost reached the Gold certification, even. So although it isn't perfect with overall efficiency, it does a good job of being close to it. We'll see how our review unit fares in the tests.

 

As with its big brother, the X4 1600w, installation is quick and easy due to its modular design and included accessories. The X4 is designed to reduce noise. It features a 135mm dual bearing-cooling fan providing increased airflow for longer life. It also includes a silicone chassis bracket intended to reduce vibration noise. The X4 series features a lifetime warranty.
