Lee is at it again, this time pitting the Zalman ZM1000-HP 1,000W Power Supply against our abusive teting policies, to see just how much it can take.  As it turns out, this PSU has a lot going for it, deserving the 80+ rating it received and keeping the temperatures and sound level reasonable, even at full load.  That comes partly from the fact that the HP part of it’s name signifies that this PSU uses heatpipes to deal with some of the hot spots.  Read on to get the full picture on this powerful PSU.

“The ZM1000-HP 1,000W power supply’s voltage regulation, line regulation and cross-loading regulation are excellent. The overall efficiency is excellent and AC ripple noise suppression is very good. Under normal operating conditions (below 600W load) the ZM1000-HP is virtually silent. The PSU comes fitted with a large assortment of hard-wired and modular cables that can support multiple, high-end video cards. However, the cables are only 20″ long, which may prove a bit short for use in some larger cases.”
