6. 24-pin ATX power connector
The main power for the motherboard is located on the right side of the board
and perpendicular to the PCB; this is also described as a "Vertical" connector
(See Page 37 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 EPS and ATX, have been added
to reduce the load and increase longevity due to wiring and trace limitations.
7. 8-pin EPS Connector
The EPS is dedicated power for the CPU (See Page 38 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 to only work with an EPS or CPU cable. System
builders sometimes make the mistake of plugging in a PCIe 8-pin or 6+2-pin
connector, which will prevent the board from completing POST and possibly
short or damage the board. Although PCIe and EPS cables appear similar, they
are wired differently and attaching the wrong 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. 4-pin Supplemental ATX Connector
The ATX power connector on the Z490 FTW provides additional power to the
CPU. This connector requires the appropriate 4-pin ATX power that is
provided by your power supply – often as part of a 4+4-pin CPU connector.
(See Page 36 for more specifics to the connector itself, and associated
wiring/pinouts). This connector is not essential to running the system, but may
provide additional power to the CPU under a heavy load, overclocking, and/or
benchmarking. The 4-pin power connector may be installed in addition to the 8-
pin EPS connector; it may not be installed in place of the 8-pin EPS connector.
9. Intel SATA 6G Ports

The Intel Z490 PCH has a 4-port SATA 3/6G controller (See Page 48 for

specifics on the connectors). This controller is backwards compatible with
SATA and SATA 2 devices, and supports SSDs, HDDs and various types of
optical devices (CDROM, DVDROM, BD-ROM, etc.). The controller also
only certifies the speed of the
