Computer power supplies have come a long way from the old days of the early Pentium era. Back then a 150 Watt power supply was more than enough to power a system. Fast forward to 2007 and there are 1200 Watt power supplies on the market for the extreme enthusiast with a monster system. In addition to the ridiculous amount of power these new units can provide, they have had a huge makeover since the old days. Many have large 120mm fans, some have colorful lighting, and some even have modular cabling to reduce clutter inside the case.
Kingwin is one manufacturer that recognizes that performance is important, but individuality is high on the list of desired features with many computer enthusiasts. Most of the products they manufacture are very eye-catching, and this is an understatement when looking at their new Mach 1 800W Power Supply, model number ABT-800MA1S. This unit is rated for 800W continuous output, has rather unique modular cables, and has many blue lights throughout.
