"What separates the Ultra X3 1000W Modular Power Supply from the many other's that are on the market is, it's completely modular. Some power supplies within this 1000W range say their modular, but the main motherboard leads are still hard wired into the power supply. This power supply comes with a very quiet 135mm fan which provides fantastic cooling and means this power supply can be used in almost any environment. I also like the fact that the Ultra X3 line of power supplies range from 600 watts to 1600 watts, so the user can pick a model for their power requirements.
