The Kingwin LZ-1000 does a nice job of improving on the Mach 1 design.  I found the new Crystal Cube Connectors to be attractive and easy to work with.  There was never any doubt when things clicked into place and the lights came on.  But the LZ-1000 is not just about fancy lights and plugs, the performance was stable both at idle and load. - Club Overclocker

The Kingwin Lazer Series LZ-1000 PSU with Crystal Cube modular cable management delivered good voltage regulation (especially on the important +12V rails) with relatively clean outputs and good efficiency.  The LZ-1000 PSU is very quiet at low to mid power levels, includes a good assortment of both fixed and modular cables/connectors. - PC Perspective

"Kingwin proved itself stable on each of its rails with less than 1% deviation from spec with output. The variable speed 140mm fan never spun up to be notable regardless of room temperature or load condition" - Overclockercafe.com
