What is the lowest wattage system you can achieve?

My new Core 2 Duo system idles at 25W DC. Load is 36W (measured at the output from the AC/DC brick).

MSI 945GT Speedster
Core 2 Duo T5600 - 1GHz/0.85V idle, 1.86Ghz/0.87V load (down from 1.1V)
1 x 1GB DDR 667
120GB Momentus 5400.3 laptop drive

There's a Zalman 7000 atop the CPU so the system is fanless, even with two Prime95s running.

C states higher than C1 aren't supported on this motherboard so idle power has the potential to be lower with a motherboard that does (e.g. the Asus).

What power supply are you using and how are you measuring power? Just curious....

I guess with pico psu.

Nice figure the 25W but it is a 500$ set mobo+cpu. It's very expensive for what it gives in my opinion.

Power supply is a Morex D2D thing (cheap off eBay). I don't have a AC power meter so I'm measuring current and voltage with a multimeter at the input to the DC board. The motherboard and CPU were two very lucky purchases and together only cost me £70, so a good deal from my perspective.

At under £120, an IL90MV and T2300 setup should give similar results (results in the linked thread could be further improved by undervolting - my old T2300 could was fine with minimum 0.95V at all times). However the Athlon BE is probably a slightly better value for money proposition.

My system runs Linux, for which I prefer Intel.
