I can't help but wonder how much more powerful desktop PC power supplies can get before they can no longer fit the ATX format. There are several 1200 watt models out there now. Yeah, there are a few that are longer than the standard, but even they will easily fit into most mid-towers. I suppose within a year or two, upper end systems will require an external PSU, or there will be a significant change to the standard case format.

I remember maybe two years ago when the first 1kW PSU came out. Many people laughed at the thought of ever needing something that powerful. Personally, I thought that it was very cool…and would probably be the norm once that SLI really got off the ground. Today, 500 watts is about the minimum for a single, powerful video card rig, and anything less than 600-650 watts on an SLI rig may give the owner some problems.

Kingwin, aka KWI Technology Inc, has been around since 1992, which makes them one of the oldest aftermarket hardware companies in the industry. They started out making CPU coolers and external HDD racks, and now are into liquid cooling, cases, high performance air cooling, power supplies and some pretty innovative storage solutions. They pioneered the use of aluminum in external storage enclosures, which led the way for its use in cases.

You probably don't think of Kingwin as a power supply manufacturer. But, if you think about it, many of the popular brands of quality power supplies from well known companies that are out there now, i.e., Thermaltake, OCZ (the OCZ branded, not their PC P&C division), Corsair, Silverstone, NZXT etc, weren't around a few years ago.

The Mach 1 came along at the perfect time for me, as my previous PSU died while it was on the way. It didn't die completely, It made a “pop” (while I wasn't home), and I started getting random reboots. Unfortunately, I didn't listen to my wife when she mentioned the “pop”, and having preconceived notions of what was wrong, it took me a couple of days to realize that my PSU was the problem, and in the meantime, I caused some other problems. A couple of days later, the PSU arrived and saved the day.

Kingwin PSUs are packaged in this attractive box. There is plenty of information on the outside, pretty much everything you'd need to know short of the actual specs

Opening the box, I see that Kingwin has gone to the trouble of some nice packaging to add protection to the PSU, which is also bubble wrapped, and there is a slab of Styrofoam in the bottom of the box.
