Hi, I am planning to construct a new allround server for at home. One of my goals is low power usage, for this I am basing my build a bit on the HTPC build as presented in this article. (with a 2120T instead of a 2100T due to availability) Now I am wondering however how much influence my power supply has on the total power usage. In that article he gets 22 watts at idle. I have a 380 Watt PSU lying around, will this influence my idle power usage ? Does PSU get less efficient at lower power usage ? Should I get a more specialized PSU of 150 watts for instance ?
