Provides power to the motherboard – can be split into 20-pin and 4-pin
connectors, for compatibility with older ATX motherboards.
WARNING:
Do not use the 4-pin connector of this cable as an
ATX 12V 4-pin connector
–
they are incompatible.
Provides power to modern CPUs – can be split into
two 4-pin connectors, for compatibility with older
motherboards and systems with limited power consumption.
Note:
Some motherboards, typically dual processor systems,
may require a secondary 12V connector – refer to
the motherboard manual for details and connector locations.
