Mach 1 Features & Specifications

Like an smart company, Kingwin wants to bring a solid product to the table for their first release. Judging from the features and specifications listed below, the Mach 1 800W modular power supply appears (on paper) to be a good first addition to the other very promising products in the lineup.

Total Power 800W continuous output @ 50C ambient temperature

We certainly appreciate that Kingwin designed the ABT-800MA1S to offer plenty of convenience, but there's one item in the specifications which glares out: 800W Peak Output. Since most other power supply units we test have long since given up on selling their product under a "peak output" number, it's surprising to see it done with the Mach 1.
