If your Christmas shopping list includes a power supply and money is not a problem, then go get the Zalman ZM-1000HP now! But only if you can live without a power switch. This and the longer size are the only two shortcomings I can find with this unit. I don't understand why Zalman has added a useless "standby filter" switch but no power switch, which costs something in the neighbourhood of 2 cents to implement.
During all our tests the ZM-1000HP could deliver excellent results. The choice to go both fixed and modular cable gives you the best of both worlds: High quality power and no cable clutter to keep your case inside clean. Even though the form factor is a bit bigger, most cases which actually need a 1000W PSU should have plenty of space to accommodate this power supply.
In case your budget is a bit smaller, you can also go with the ZM850-HP which we reviewed here. It is essentially the same unit just with 850W and a smaller price tag (and still no power switch). The fan noise, or lack of it, is one of the properties you will love most once you one of these new Zalman power supplies. Personally I am using the ZM850-HP in my system and would never go back to a louder PSU.
