A Closer Look



The Kingwin Mach 1 is covered with a shiny black powder coat. It is less shiny than many I have seen, which is fine, shiny generally means lots of fingerprints. Anyway, if you look at the placement of the informational stickers, you aren't going to see a lot of paint when the PSU is mounted anyway.





Kingwin's Mach 1 sports a single 140mm fan. Yeah, it is as big as it looks. Placing a 140mm fan in a PSU is the max you're gonna get in the standard ATX format, and that leaves no room for the rear 80mm fan that is in most of the PSUs that have a 120mm fan. To be honest, I've never really understood that 80mm fan…it doesn't extract all of the air inserted into the PSU by the 120mm, and unless there is other venting, it makes the intake fan actually work harder just by being in the way. Though, I have to admit, it does look odd not having that second fan.

Another item that sets the Mach 1 apart is the “aircraft style” modular connectors. I guess I haven't mentioned yet, this PSU is modular designed. Having spent some time in the army, most of which was around communications intercept equipment, and being around amateur radio for most of my life, this type of connector is pretty familiar to me, but I guess it is the first time I have seen it in a PC application. If nothing else, there is coolness value just because it is different.





The Mach 1's cables are in this nice plastic case, which served as extra protection for the PSU while in the box. It comes with six cables: 2-PCI-E each with two PCI-E connectors, 2-SATA each with three SATA connectors, and 2-standard power cables, each with five nice 4-pin Molex connectors. All of the cables are plenty long enough for a mini-server sized case, and covered in this cool mesh, which, for a change, isn't intended to stealth your cables, but to highlight them. Face it, with all of the power connections required today, you just can't hide them all, so you may as well use something cool to cover them with. Each end is finished in heavy heat shrink tubing, finished nearly 1” over the mesh, making it pretty unlikely that the mesh pulls out…something that has happened on other power supplies I have owned.

I guess that the only complaint I might have is I'd like a little more distance between the the PSU and the first 4-pin Molex on each modular cable. Both cables are identical in length and connector placement, with the first connector positioned for the optical drive bay. My motherboard requires a 4-pin Molex on the bottom rear corner.



Finally, the Mach 1 comes with a 16ga cord (as opposed to a lighter 18ga) and an owner's manual.
