  • Bad:


  • Good ripple and noise suppression, did 1200W, extremely flexible cabling, lifetime warranty, ran at full power well above rated operating temperature, overshoot transient suppression well above average.
  • Great warranty, Clean design, Great Modular means less cables getting in the way of your cooling, Solid Voltages, Small! I have yet to see a standard sized PSU over 1000W until the X4.


  • Somewhat sloppy build quality, no overtemp shutdown until it was almost too late, one must run the combined 3.3V and 5V rails almost wide open to get to 1200W.

Overall motherboard sensors arent the most accurate test of a power supply Judging by our 3.3 volt reading on the motherboard we cannot trully draw a proper conclusion from onboard testing. As for the LCD test we see that the Ultra X4 is well...
