4.7.1. External Graphics
External graphics is supported through one PCI Express 16-pin graphics slot allowing for bifurcation (2x8, 1x16 or
1x8 + 2x4). For more information, see Chapter 8.15.1 PCI-Express x16 Connector (J4).
4.8. Power Consumption
In order to ensure safe operation of the board, the input power supply must monitor the supply voltage and shut
down if the supply is out of range – refer to the actual power supply specification. In order to keep the power
consumption to a minimal level, boards do not implement a guaranteed minimum load. In some cases, this can lead to
compatibility problems with ATX power supplies that require a minimum load to stay in regulation. Additionally, the
voltage range +12.6 V to +13.5 V is not recommended.
The mITX-SKL-H is powered by either a single+ 12 V to +24V DC jack rear-barrel supply or by using a standard ATX
power supply to the internal ATX +12 V 4-pin connector with a suitable cable kit and PS_ON# active.
ATX12V supply: ATX+12V 4-pin connector must be used in according to the ATX12V PSU standard.
Hot Plugging the power supply is not supported. Hot plugging might damage the board.
