You can't help the idle numbers, but you can improve the load power consumption: at stock clocks you should be able to undervolt the CPU by at least 100mV. (I stress tested -120mV @ 2100Mhz) Also make sure you install the Realtek LAN drivers. That might shave a bit too, as the Windwos default drivers don't have proper power management.The Asus AM1l-A(+Pico PSU) is not so power friendly as my ASRock board(jack+12V adapter).
The picoPSU might also be responsible for some of the losses. Your idle power usage was only ~1W lower than mine, and I'm using a 350W ATX PSU. Hardware.fr also did a review with Asrock AM1B-ITX + 90W picoPSU and got only marginally lower idle numbers.The Asus board is not very nice regarding idle consumption. I tried to bring it down but overall it uses 5W more in idle or light surfing mode which is too much difference for me.

What I really like about the Asus card is being able to undervolt.
PS I saw(in A-Tune) my 12V mobo voltage is 10.7 V with a 12V supply. No problem because everything is converted to 5V and lower and the SSD uses no mechanical motor.
Only 12V hardware is the CPU cooler.......this 10.7V makes it only quieter.
I can test it with a DVD writer/player. The only things that use 12V directly are electric motors, all else is attenuated to 5V or less. I don't know about the charging your mobile while its off. I think you should find this in the manual.I like the power supply that you are using. Small size, cheap and low power usage. I intend to build a similar system as yours. But I want to add a slimline BluRay/DVD drive. Is the 12V line the only line with a decreased voltage? I think that a 2,5” SSD uses the 5V line to power it. Do you happen to know if a slimline BluRay/DVD uses the 12V line or the 5V line. I assume it uses the 5V line, but I’m not sure. Do you think it would be possible to power mobo, cpu, ram, SSD, a slimline slimline BluRay/DVD drive and some usb devices (IR, BT, Phone) with this power supply?Can you tell me If the usb ports still supply power when the system is shut down? Can I charge my phone on a usb port when the system isn’t running?
