Power Connector

The Ten64 board has an eight-pin, 3.0mm pitch "MiniFit"-style power connector that supports both DC (e.g from a plugpack) and ATX power supplies (with 5VSB and power on/off) via an adaptor. Power Connector - P2

ATX adaptor schematic

An ATX power supply adaptor is available in our 'Mini-ITX' kit (sold separately from the appliance).

Assembled ATX adaptor cable

Note

Ten64 only draws power from the +12V rail. Older ATX power supplies might shutdown soon after boot, when little or no power is drawn from their +5V or +3V3 rails.

On some datasheets this is indicated as 'Zero minimum load on 3.3 V rail' support or similar.

If 5VSB is present, the onboard microcontroller will go into ATX mode and assert PWR_ON once PWR_GOOD is indicated by the supply. If a power down command is issued by the software, the microcontroller will deassert PWR_ON to effect a shutdown.

Note: This is not the same as the ATX12VO connector, which is a larger, 4.2mm-pitch connector and uses 12V instead of 5V for standby. Nonetheless, an adaptor may be provided for ATX12VO in the future.
