3.7. Power Supply
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. Please note, 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. The ATX-
KBL-S board must be powered through the ATX+12V-8p (8-pole) connector using standard ATX12V power supply and
through the ATX-24p (24-pole) connector using standard ATX power supply.
ATX12V supply: ATX+12V-8p connector must be used in according to the ATX12V PSU standard.
ATX supply: ATX-24p connector must be used in according to the ATX PSU standard.
Hot Plugging power supply is not supported. Hot plugging might damage the board.
The requirements to the voltages of ATX power supply are as follows:
