Kingwin ABT-1220MA1S Mach 1 Power Supply
 

Like the last time we reviewed a Kingwin Mach1 there are a lot of things to like about the KINGWIN Mach 1 ABT-1220MA1S from its excellent modular connectors, to its extremely quiet operation to its very beneficial 12v rail arrangement. However, unlike the last unit this unit gives us no real "buts" to our assessment as the unit also features excellent efficiency, excellent voltage regulation, and very good DC output quality. It seems as if Kingwin has addressed all of the concerns we had with the last Mach 1 and come back with a unit that is certainly in the same league as the better known power supplies on the market. If Kingwin would pair this PSU with top tier support and a warranty much more robust than the current 1 year warranty supplied this unit would be hands down one of the best 1200w+ units we have seen. As it stands there were no performance metrics that the Kingwin failed to achieve in our testing overall, and the retail cost of $329.99 puts this unit right in the sweet spot of excellent 1200w+ units on the market.

The KINGWIN Mach 1 ABT-1220MA1S power supply is easily a HardOCP Editor’s Choice Gold Award winner when looking at testing alone. The one caveat the buyer needs to be aware of is that their shiny new ~$330 PSU is only backed with a 1 year warranty. We would feel much more comfortable suggesting your buy this unit if it carried a 3 year warranty at the least.
