At Lopoco, we really know low power. Our servers are very low power. And we focus on servers that make sense from a power consumption standpoint. Do you need a server for an embedded appliance application, but don't want to add another 500 watts to your power footprint? Look no further.
The power draw at the wall socket is the power you pay for. Many server vendors list one or two servers as low power or "power smart". But really, low power is not what they do. Chances are, their "low power" servers use near a hundred watts, just at idle. If you ask them how much power does their low power server use at the wall socket, they likely will not know. They might tell you it has a 300 watt power supply, or that it has a 65 watt TDP processor. But neither of those tells you what power it draws at the wall socket.
