DC Connectors
ATX 24-pin [20+4]
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 a ATX 12V 4-pin
connector – they are incompatible.
ATX12V / EPS12V 8-pin [4+4]
Provides power to modern CPUs – can be split into two 4-pin con-
nectors, 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.
PCI-E 8-pin [6+2]
Provides power to high-performance graphics cards – can be split into
6-pin and 2-pin connectors for use with graphics cards that require
6-pin connectors, or used together for
graphics cards that require 8-pin connectors.
WARNING: ATX12V and the PCI-E connectors are incompatible and cannot
be interchanged – do not force the connectors.
SATA
Provides power to modern hard drives, optical drives and other de-
vices that require an SATA power cable.
Peripheral
