Ultra X4 1050 watt PSU

introduction

Ultra has quickly made a name for themselves in the PSU market with the introduction of their X3 series. It has been quite awhile since the introduction of the X3 series, so now Ultra is ready to launch their new X4 series of PSU's. One of the big issues with the X3 series was its efficiency. Under a full load the PSU would fall to 78% efficiency. While this isn't really bad, its not enough to be certified for 80+. This time around Ultra has went all the way, and obtained the 80+ certification.

Ultra could have easily stopped there, and we would have been perfectly fine with it, but they decided to add just one more thing, 50 more watts. While thats not a whole lot, it certainly makes the PSU stand out just a little bit more than a 1000 watt PSU. Today we will put the X4 to the ultimate test, and see if it really improves on the X3 series of PSU's.
