Final Thoughts and Conclusions
The X3 600W modular power supply is another excellent addition to Ultra’s X3 power supply line and should appeal to mainstream enthusiasts who don’t need a 1kW PSU.  The build quality appears to be excellent and the output voltages were all very stable and clean, even when delivering 600W at 40°C.  And modular FlexForce cables, a black-chrome finish, active PFC, and a lifetime warranty are nice to have also!

The Ultra X3 600W modular power supply has a typical street price of $129.99 USD.
