PC Stats posted a review on the Kingwin Absolute Power ABT-600CW Power Supply

The modular cables included are each sleeved very well with the heatshrink tubing butt up right to the edge of the connectors. The only exception being the main motherboard cable which has about a 2" gap etween the heatshrink and the 20+4 pin connector. This must be to allow for greater flexibility since this bundle is often rather stiff without extra wrappings.
