Zalman has successfully added another high-quality power supply to their line up. The ZM1000-HP Plus 1,000W power supply’s voltage regulation, line regulation and cross-loading regulation are all very good. The AC ripple noise suppression is excellent and the
overall efficiency is good. Under normal operating conditions (below 500W load) the ZM1000-HP Plus is virtually silent. The PSU comes fitted with both hard-wired and modular cables that can support multiple, high-end video cards but not dual CPUs.
