Building a very low power, full featured desktop

For a few years now, [mux] has been playing around with extremely efficient computation. In 2010, he built a fully featured MiniITX / Core 2 duo computer that only consumed 20 watts. Last year, [mux] managed to build an Intel i3-powered desktop that was able to sip a mere 8.3 watts at idle. He’s back at it again, and now his sights are set on a fully featured Intel i5-powered build with a built-in monitor that will draw less than 6 watts of power.

Like his previous 8 watt i3 build, [mux] reduces the power requirement of his build by carefully measuring the power draw of every component on his board. The power savings come from a simple fact of any power supply; when converting from AC to DC, or from one DC voltage to another, there’s always a little bit of power lost in the process.

[mux] reduces these power losses by removing a few voltage regulators and re-routing power lines across his motherboard. So far, the power draw on [mux]‘s computer is more than half of what it was when the parts were stock, and we can’t wait for the finished build that includes a built-in monitor, UPS, and a proper case.
