Zalman ZM850-HP Plus 850 W

27 April 2011
  • Summary: The most significant feature of the ZM850-HP Plus is, without any doubt, its cooling system that utilizes a dual heatpipe heatsink for silent operation. Indeed even with over 50°C ambient and at full load the cooling fan worked silently enough, at least for my ears.
  • Pros: Dual heatpipe cooling system for silent operation, High efficiency throughout 20-100% load, Tight voltage regulation at +12V and under 3% for 5V, Excellent +12V performance in Advanced Transient Response tests, Very good ripple/noise suppression at +12V and 3.3V, Supports up to three hi-end graph...
  • Cons: High price, 3.3V outside ATX spec during 2nd Advanced Transient Response test, 210 mm long, might not fight all cases, Mediocre efficiency at, Lacks a second EPS connector, Power distribution not optimal

14 January 2011
  • Summary: The new Zalman ZM850-HP Plus disappointed us. It failed our tests by presenting a voltage below the minimum allowed on its +3.3 V output. On the other hand, noise and ripple levels were always low.

Zalman ZM850-HP Plus PSU

23 December 2010
  • Summary: We initially plugged the PSU into an EZ PSU Tester 3 in order to power it on for our "idle" measurements.  As noticed below, the voltage rails were fairly stable with no load, but these aren't necessarily indicative of overall load performance.  According to our Kill-a-Watt, the power draw was 4W.
  • Pros: Low electrical noise, Rated at 850W Continuous, Lots of peripheral and SATA connectors, Stable with a fairly heavy load, 14cm fan is very quiet and cools well thanks to dual-heatpipes
  • Cons: Large size may not fit in all systems., +12v3 rail got a little noisy, but stayed within spec.

Zalman ZM850-HP

15 September 2007
  • Summary: The Zalman ZM-850HP is not just another 850W power supply. It is engineered from the ground up to be silent and efficient. Two heatpipes on the inside transport heat away from the hot components to the rear of the PSU where it is exhaust by a big slow running 140 mm fan.
  • Pros: Very very quiet, High efficiency, Modular, 8-Pin connectors for new VGA cards, Four PCI-E power connectors, Lots of connectors, Cables sleeved, 3 Year warranty
  • Cons: Expensive, Takes fingerprints, No power switch, Only 18A per 12V rail, but six of them, Longer than ATX standard, 21 cm
