Zalman which is famous for its high quality copper heatpipes and very quiet PC cooling hardware started releasing high quality, quiet and efficient power supplies not long ago with 500w and 600w models with integrated heatpipes to cool its innards. Zalman is upping their ante into this crowded market with a new 850w and 1000w model for those extreme users. I reviewed the 600w version back in December 2006 and it was quite nice so I expect the 850w version I'm reviewing today to be more of the good stuff. Read on to find out if it lives up to the Zalman name.
