To say this power supply is "large and in charge" would be an understatement.
The X3 1600w is the single largest capacity power supply we have seen to date in the consumer market and may well be for some time for reasons we will discuss later. In launching the X3 1600w, Ultra is thumbing their noses at the competition who are just now pushing out 1200w and 1300w units. These claims of 1600w power supply are lofty but if Ultra can deliver on those claims, and those claims can be realized by the average user, it will translate into a real workhorse power supply that could literally power several of today’s high-end PCs at once.
So does the X3 1600W live up to the lofty claims? You'll have to read the review at HardOCP to find out.
