Mainstream PC power consumption just got a whole lot better with this 25w at idle build:
- Core i5-661 – 32nm dual core CPU ¹ ²
- MSI H57M-EG65 – micro ATX motherboard
- Toshiba MK6465GSX, 640GB, 2.5,” 5,400 RPM, SATA 3 Gb/s, 8MB Cache
- Fortron FSP220-60LE 220W PSU
The PSU is matched to the predicted consumption of the build – so any old PSU will not do for this build.
At first glance this looks like an ideal build for the up-coming Windows Home Server (Vail) based on Server 2008. The idle power consumption is great for a machine that will be running 24/7 but there are some gotchas too:
- Core i5 is currently an expensive CPU (approx $200) compared to current AMD offerings.
- only 1 DIMM is populated (for maximum power conservation).
- notebook hard drives are used for maximum power conservation – WHS will require multiple drives.
¹ 900 mhz IGP instead of the 733 MHz found on all other Core i5 and Core i3 models. The result is a TDP of 87W, rather than 73W.
² CPU is undervolted by 0.5 volts.
