Recently, an article at The Inquirer boasted that the new nVidia boards will be pulling more than 180W each. Some quick calculations will tell you that overclocking an Intel Q6600 to 3.3GHz at 1.4V pulls more than 160W. With triple SLi or CrossfireX, one of those Skulltrail motherboards pimped out with two QX9770s, or a full water setup to keep it all cool, you're easily looking at a load that no normal power supply can handle. Not that I know why hotcakes are selling, but it's no wonder why power supplies rated at 1,000W (1KW) or more are selling like them.


Kingwin has been around since 1992 and has recently started promoting their high-end Mach 1 power supplies. Last September, we had a chance to review their Mach 1 800W PSU, and today we have for review their Mach 1 1,000W PSU, the ABT-1000MA1S. With six 12V rails, four rated at 20A and two at 35A, a hefty 150mm fan, and a unique modular cabling system, this power supply has a lot of promise. Full specifications and power chart from the Kingwin website are:



Again, the ABT-1000MA1S has all the makings of a great power supply: 80+ efficiency, huge output, an intelligent, convenient modular system, and well-sleeved cables. As is always the question, though, can this PSU keep up with the competition, or is it just for show? Continue as we find out…
