Zalman ZM1000-HP 1000W PSU reviewed at Driver Heaven

Driver Heaven has a great review of this Enhance built, dual transformer beast.

In order to efficiently test a power supply unit, one must first be able to deliver specific load quantities. Simply connecting it to any kind of PC system will not work, since the load does not only vary depending on the system state but the precise power consumption is also unknown.

Amen to that!  Make sure to check out how Grace handles the Zalman under fire (find the pun there.)
