Looking back at the testing, we see totally solid performance from the Mach 1 all around. The 12V line had no variation whatsoever, the 3.3V line had a ripple of only 0.01, and the 5V line still had great performance. Granted a single Core2 Quad and an ATi Radeon HD3870 cannot put a gigantic load on a 1KW PSU, the Mach 1 handled everything we could throw at it very well.
During use, the 150mm fan keeps the unit cool, never spinning up to an audible noise, while still putting out a good volume of air. The fan's blue LED isn't too bright, which means that it's nice to look at if you want it there, but easy to ignore if you don't. Likewise, the LED indicators for each modular connection give a nice look, while still out of the way enough to ignore.
All of the cables that come with the Mach 1 are sleeved in a nice black and yellow mesh, and should all be long enough to fit a bottom mount system in a full tower case. Kingwin also did a good job here thoroughly heat-shrink wrapping the ends of the mesh. While the Molex cables are quick-release, the SATA cables aren't right-angled, which would have been a nice feature. Lastly, the aircraft style modular connections do a great job of securing each cable while keeping a foolproof design.
The Mach 1 can be found for $289.99 at a popular online reseller, which is a fine deal for such a great product. OCIA.net awards the Kingwin Mach 1 ABT-1000MA1S 1,000W Power Supply our Seal of Approval.
