It has been a very long time since Ultra has came out with their X3 series power supplies. While these power supplies came with large power outputs like 1600W, their efficiency and noise, however, was just not up to par with other manufacturers. With the release of the new Ultra X4 series power supplies, these problems were taken into consideration and were fixed to give the best experience to the users. The new X4 series power supplies are certified with the 80Plus certification and they come in wide variety forms. Some of the X4 power supplies have a bronze certification while others have a Silver certification. In todays review, we will be taking a look at the Ultra X4 750W Modular Power Supply, that comes with a 135mm silent fan, and is 80Plus Bronze certified. We are going to compare it to the older X3 brother and some other power supplies provided by other manufacturers. Lets take a look at whether the X4 power supplies are up to par with the other high end power supplies.
