Server Input Power

How do I figure out the Rated Input Power for a server. The spec sheet gives it as Rated Input Power 1000/1056/1205 W

To figure out the BTU, I need the actual number.

HP DL380 G5

Actually I mean Output Power it lists it as - Power Supply Output Power (per power supply) Rated Steady-State Power 800/850/1000 W

Eh, never mind. Found it.

Install their Power Advisor and calculate the exact power consumption for your config. You can also run a web version. Just remember the important thing is getting cold air into the front of the server and clearing the hot air away from the rear!
