Este post va en ingles, basicamente porque ya lo tenia escrito de antes en este idioma asi que ahi va, suerte:

PicoPSU-120 12V DC-DC ATX power supply features:

• 120 Watts
• 12V input
• 100% silent, fanless
• Over 96% efficiency
• Plugs directly into the ATX connector
• Intel Core Duo compatible
• Perfect for mini-ITX boards

To supply the PicoPSU is also necessary an 12V external AC-DC power brick adaptor, I am using a 5 A one, which in theory generate 60W (5A x 12V = 60W.) that means that the PicoPSU cannot reach the top, 120W, only is able to obtain 60W, but this is not a problem, because 60W is more than enough for the designed embedded system.

The reason because I am using the 5 A externeal brick instead of the ideal 10A (which can generate 120W) is the price, a 10A one can cost more than the double and for me is not necessary.


Connecting 120w PicoPSU to the board:
The process is very simple:

1. Plug the PicoPSU directly into the ATX connector of the mother board.
2. Connect the PicoPSU to the external AC-DC 12V external brick.
3. Plug the brick to 220V.
4. In this moment, the microprocessor fan will turn a half of turn, and the led of the PicoPSU will light.
5. To turn on the computer, is important to read the Case Connector functionality from the MII 12000 users guide:

Case Connector: F_PANEL
The F_PANEL connector block allows you to connect to the power switch,
reset switch, power LED, HDD LED, SLED and the Speaker on the case.

• Power Switch (PW_BN):Connect to a 2-pin push button switch. Pressing this button will turn the system power on or off.
• Reset Switch (RESET) The Reset Switch is used to reboot the system rather than turning the power ON/OFF. Avoid rebooting while the HDD is working. You can connect the Reset Switch from the system case to this pin.
• Power LED (PWR LED) The LED is lit when the system is power on. If the system is in S1 (POS -Power On Suspend) or S3 (STR - Suspend To RAM) state, the LED will blink.
• HDD LED: HDD LED shows the activity of a hard disk drive. Avoid turning the power off while HDD LED is lit. Connect the HDD LED from the system case to this pin.
• SLP_LED: The SLP_LED is lit when the system is in the S1 (POS - Power On Suspend) state.
• Speaker: The speaker from the system is connected to this pin.

Therefore, to turn it on, just put a push button switch (and press it) or put jumper between the pins 6 and 8.
