This model's power consumption according to the datasheet: TBD (I kid you not!)
Maybe it's efficient but the nano-ITX AMD board isn't encouraging with a maximum power draw of 31W.

In the meantime they have similar Atom boards with regular chipsets which (they claim) consume 9W max. That's interesting. Other boards consume a bit less but use the same chipsets as fit-PC or Soekris which may or may not be a problem when it comes to drivers. I expect more efficient boards will be released at a later date.

Ok here we are cedar trail is out: n2600 3.5watt!!

I have found this motherboard: Jetway JNF9C-2600.

Any idea about idle power? A silentpc review?

Thanks,
Mario

Regarding the Intel D945GSEJT, I`m using one and got exactly the same power figures as in the SPCR review: 12 watts idle and 18 at full load (including a 2.5inch drive, 1gb of ram and a low speed fan). So, it`s not the most efficient but it should be pretty good value and easy to find. It cost me 85 euros 3 years ago and the built in dc/dc power supply means you won`t have to spend more for a pico psu.

The jetway JNF9C-2600 also looks promising, essentially a more modern equivalent of the GSEJT. I also suspect it`s going to be cheaper than more specialized options like the Axiomtec board you mentioned.

We should have samples of that Jetway and the Intel DN2800MT in the next week or two -- and a report on both. The Intel features Atom N2800 (1.86GHz Dual Core, hyperthreaded) 6.5W TDP chip.

Great news to hear!!

I add some other motherboard I have found meanwhile:

jetway NF35-T56N / NF35-T40E
axiomtek pico100
ibt MI958
ibase MI958

This ones are based on amd G-series embedded apu at 5/9W

Bye,
Mario

Intel DN2800MT Marshalltown (probably the closest to the low power requirement)
Jetway NF81-T56N Brazos
I would only pick from these 2 boards as I think starting 2012 msata is a must-have feature for Mini-ITX.

or you need to find a used Pineview or Poulsbo laptop and gut it.


btw, I could buy a refurbished 1001px (n455) for a reasonable price. what do you think it could be the power draw on average load - with the lcd in sleep mode, and possibily with a SD card as a primary drive? would it make sense as a small low power server?

poulsbos are very difficult to find....

I don't know but the specs says it can run on 5.3W (with the LCD powered up, the drive and stuff) when it's on battery.
But the power consumption when it's on AC may be a lot higher. My guess is that if you use a reasonably efficient brick, you'll get around 5W but there's no guarantee...

Personally, I wouldn't bother unless the laptop came very cheap. Broken out-of-warranty laptops are ideal for this purpose.

If I'm going to spend real money, I'd rather get gear that's easier to work with and that's more flexible.
If you get a DN2800MT plus a very efficient brick, you'll probably get a higher power consumption, but only by a few watts and you'll have better I/O and probably better reliability. In my opinion, it's well worth the extra watts (unless you're running on a tight solar budget or something). The Cedar View graphics driver issue is a PITA though. Hopefully it'll sort itself out down the road.

What ARM solutions are supported by Debian (or another normal Linux distro)?

The Raspberry Pi supports Fedora, Debian and ArchLinux. Do any of those distros work with LAMP or XAMPP?
