Power supplies are the heart of any system, just like our hearts the power supply provides power to the PC system, and without a solid stable power supply your system can fail. There are many aspects or features to PSUs as well, some come with your standard hard wired cable layout while other are modular allowing the end user to pick and choose which connections they need which is nice when you want or need the power but don't need all of the included connections hanging around.

Up on the review block today is the Mach 1 900Watt Power Supply from Kingwin that not only looks great, but features an interesting modular cabling system that securely locks the cables into the PSU to insure they will not come loose. During my time with the Mach 1 I found it to be a very quiet and exceptionally stable power supply that will meet or exceed the demands of most high end system on the market today.
