Zalman ZM600-HP 600W Power Supply Unit Review
 

So, what's the deal with the ZM600-HP? Zalman says it is ultra-quiet power supply complies with ATX12V Version 2.2, and supports the latest dual-core CPUs, as well as the latest dual graphic card systems (SLI) so it looks like the type of PSU most builders are in need of. The 600W output means it is not one of the more powerful units available, in fact, it has about half the power of the high power units making all the headlines lately, but if you are looking to build a quiet computer or you are not running two high-end video cards, you don't need a 1000+ watt power supply. Plus, 600W from Zalman should mean 600W, so there is no need to compensate for a supposedly high power PSU.
