Hi Martin and the rest of you Due to a regulation on watt pr. squaremeter (=heat) in the datacenter we use (InterXion) we have spent a lot of time finding new boards, cpu, psu, ram et al for the servers we use for dedicated serverhosting. All items are measured with different kinds of 'Fluke' volt-meters and on differnt places. Don't know if you folks can use it, buthere goes:
CPU (Intel P4 2,4) 63Watt CPU (Intel Celeron 2,2) 54Watt PSU (150Watt with ~70% allocated to 3,3V and 5V) +20-30% on power-on! RAM (Kingston pc2700 512MB) 2,5Watt BOARD (ASUS and DFI onboard LAN, 32MB video, sound) 25Watt DISK (IBM and Seagate ATA133, 40GB) 12Watt CDrom none A complete "server" has a total of: Wake-on-LAN 8watt Idel 42-54watt Max load 92-109watt Beware of the ekstra powerconsumption on power-on! You can expect an ekstra 20-30% on power-on caused by the various circuits on the board, but not least in the PSU. This is only a feature if you work with 16amp feeds (or any other power-feed) and are on the egde of max - then you have to take the ekstra20-30% in account so that you can power all servers up at once, if needed.
