Zalman ZM850-HP Plus 850 W
 

Zalman, a company that is well known for its low-noise products, recently freshened up their PSU range with two new models, the ZM1000-HP Plus and the ZM850-HP Plus. Today we are testing the ZM850-HP Plus, which utilizes a dual heatpipe system to improve cooling of the internal components for reduced heat and noise levels.
