Zalman currently offers five different power supplies that incorporate one or more heat pipes with output capacities ranging from 500W up to 1,000W. The ZM750-HP features a combination of fixed and modular cables, support for dual core CPUs and multiple graphics card, and it can deliver up to 750 watts of continuous DC output. The ZM750-HP uses heat pipe technology to augment the internal cooling system for increased reliability and to reduce noise. While not the first PSU manufacturer to take this approach, Zalman certainly has a strong history of effectively using heat pipes in many of their CNPS (Computer Noise Prevention System) enabled products.
