Default Ultra X4 850W and 1050W Power Supplies

The Ultra X4 line of power supplies represent something of a Phoenix rising from the ashes of the Ultra X2 750W Extreme Edition. Unfortunately, someone shot down that Phoenix before it could rise far enough from the X2's ashes to really signal a rebirth for Ultra. The X4 line today showed only acceptable voltage regulation, in specification transient response, barely in specification DC Output Quality, and good exterior build quality. Unfortunately, this gets worse as the interior build quality was not very good and efficiency results that are so far off of the 80 Plus Silver that these units are supposedly certified as to make us think this is some kind of joke. As such, while not out right failures because they did not violate the ATX12v specifications or blow up, the X4 line is hardly the rebirth that Ultra needed and more like slightly warmed over leftovers on the day after Christmas.
