6. 24-pin ATX power connector
The main power for the motherboard is located on the right side of the board
and parallel to the PCB; this is also described as a “90 degree / right-angle”
connector (See Page 40 for more specifics to the connector itself, and associated
wiring/pinouts). The 24-pin connector IS directional and the connector needs
the tab on the socket to line up with the release clip located on the 24-pin
connector from the power supply. This connector pulls the bulk of the power
for all components; other connectors, such as CPU +12V EPS, PCIe (video
card AND motherboard sides), have been added to reduce the load and increase
longevity due to wiring and trace limitations.
7. Dual 8-pin EPS Connector
The +12V EPS are comprised of 90 degree right-angle dual-dedicated power
inputs for the CPU (See Page 41 for more specifics to the connector itself, and
associated wiring/pinouts). Carefully choose the correct power cable by
consulting with the installation manual for your power supply. This connector
is designed only to work with an EPS or CPU cable. System builders may make
the mistake of plugging in a PCIe 8-pin or 6+2-pin connector, which will
prevent the board from POSTing and possibly short or damage the board.
Although the cables appear similar, they are wired differently and attaching a
PCIe cable to an EPS connector may cause damage to the motherboard.
Alternatively, if no power cable is connected or detected, the system will not
POST and will hang at POST code “C.”
8. Supplemental PCIe 6-pin Power Connector
There is a 6-pin PCIe connector at the bottom of the motherboard (See Page 40
for more specifics to the connector itself, and associated wiring/pinouts). This
connector provides dedicated power to the PCIe x16 slots, augmenting the
+12V power provided by the 24-pin and the GPU directly.
This is optional for a single card solution, but is recommended for SLI, CFX,
and dual-processor video cards.
9. Intel
®
SATA 6Gbit/s Ports
The Intel
®
Z390 PCH has a 6-port SATA 3/6 Gbit/s controller (See Page 48
for specifics on the connectors). This controller is backwards compatible with
SATA and SATA II devices, and supports SSDs, HDDs and various types of
optical devices (CDROM, DVDROM, BD-ROM, etc). The controller also
