For a camera application, we were looking for a compact , low power PCI express x4 platform. At the time of selection, the POV MB330 ION-ATOM seemed the only platform available (atom pineview and arrandale were not released yet) providing these features. We did the following power measurements:
MB : Point Of View, POV ION-MB330 (miniITX, atom 330 + ION chipset and PCI express x16)

SSD: Intel, X25M-160 G
MEM: 1x 2GB SODIMM PC2-5300 (667MHz)
PS1: Deer/Allied DR-8250SFX (POV ION-CS330 system came with SPIRE/APEX case with PS1 installed)
PS2: FSP90 (90W, Pico-like PS)
measurement device: Voltcraft Energy check 3000 @ 230V
Power with XP running idle:
PS2: 20W !!!!
PS2: 22.6W (2 x 2GB SODIMM PC2-6400 (800MHz) )
Now with frame grabber installed (also idle): Dalsa X64 Xcelera-CL PX4, PCI express x4
I exprerimented also with other supplies. The results can be found at:
* (FSP) Pico PS significant more efficient, especially at lower powers.
* 2G additional memory draws 2.5...3W more
* POV MB330 ION-ATOM with 2 Gbye memory combined with a pico PS consumes < 20 Watt idle !!!!!.
The POV MB330 ION-ATOM (cost around 120 euro) makes it possible to build a small/compact, low priced, low power ( < 20W !!! idle with pico PSU ) system with PCI express x16 functionality.
