Introduction
KWI Technology, Inc., better known as Kingwin, has been around since 1992. Initially focused on cpu coolers and mobile racks, they now have external enclosures, fans, controller cards, system coolers and power supplies. Power supplies have come a long way from the simple gray boxes they once were. Nowadays those simple power supplies are out. In are the ornate ones, with modular cables, sleeved wiring and high quality finishes.
Kingwin has provided us with one of their latest power supply units, the Mach 1, which is SLI and CrossFire ready, sporting 600 watts along with attractive lighting and modular cables. Let's find out how this latest power supply unit from Kingwin performs.

Package
I arrived home for winter break to be greeted with a UPS Express box sitting on my desk. The box was in perfect condition, with no dents or tears (I guess there is something to be said for the more expensive Express options). Inside the Mach 1 box was surrounded with a generous allotment of packing peanuts. The sealed box containing the power supply was in pristine condition.
The Mach 1 packaging is full color gloss retail packing. It's lists the key features of the power supply, and is very well designed. It's not tacky in the least bit.
