With power to spare, the X3 1,000W power supply is another worthy addition to Ultra’s power supply line.  The X3 had no problem delivering the maximum rated capacity of 1kW and did so quietly and efficiently.  The build quality appears to be excellent and the output voltages were all stable.  And modular FlexForce cables, a black-chrome finish, active PFC, and a lifetime warranty are all nice to have!


The Ultra X3 1,000W power supply has a typical street price of $289.99 USD, which makes it a very good value for a 1kW power supply.
