I am considering buying a Dell Poweredge 2800 Tower 2nd hand, while I have some experience with HP's competing server brand, the ProLiant Series, I am struggling to find out the server's realistic power usage (in watts).
The server spec sheet says that the power supply is a huge 900+ watts. However this document says that the 'maximum' energy consumption is only 320 watts. I was wondering if anybody here would be able to give me some more realistic real world results.
My only guess for the huge power supply intake is that you can have a lot of room for PCI-X and PCI-E cards, which I guess could drain a lot of power.
