Zalman ZM1000-HP 1000W Modular PSUWe have just published our review of the 1000W Zalman ZM1000-HP PSU. In a world crowded with 1kW PSUs, the Zalman unit stands out as it has a 14cm fan and dual heatpipes that help keep it cool and quiet. This PSU has six +12v rails to keep your gear all running smooth and appears to be very stable as we analyze this unit with a Tektronics Digital Scope.
Take a look before you spend your cash on a $200+ PSU.
The voltage is very solid with the Zalman ZM1000-HP. It starts a little above the rated value and drops only slightly on any of the lines. The highest 12v rail (12v2) drops 0.2v and levels off at 12.2v with a heavy load. The 5v rail stays above 5v at 5.08v - down from the non-load 5.09v. The 3.3v line is even more solid and we didn't measure any drop in voltage when going from a non-load situation to a heavy 850W load on the entire PSU. . .
