about low power

lopoco v. conventional servers: An average lopoco server uses about 25 watts at idle and 45 watts under load. That means you can install as many as 80 lopoco servers in rack; something you can't dream of with conventional servers. You can even install 3 or 4 in a closet with the door shut with no risk of irking the Fire Marshall. When you factor in all the ways you will save on costs, lopoco servers are the best price/performance servers you can buy.
Summary: It's a no-brainer: with lopoco servers, you can save on your electric and/or colo bill while using less racks to build out your server needs.
