Ultra’s X3 800-watt Modular Power Supply is the upper-middle class guy in the X3 neighborhood. He hangs out in the modular part of PSU-ville and drives some serious wattage – but nothing over the top like his 1600-watt neighbor. And for the majority of systems out there running enthusiast-class, top end gear, 800-watts is generally more than enough.

If you’re in the market for a new PSU, consider giving up the excess wattage you’ll never see on that Core Duo rig, and put the difference in price towards some hardware that will really take advantage of the juice the mid-range X3’s are already cranking out.
