Component Legend Descriptions
1. CPU Socket 1151
This is the interface for the Central Processing Unit (CPU), and supports Core
i3, i5, and Core i7 models compatible with the Intel®1151 Socket and Coffee
Lake-S architecture.
2. Intel®Z370 PCH (Southbridge)
The Platform Controller Hub (PCH) handles the role that was previously held
by the South Bridge. The PCH has 4 PCIe Gen 3 lanes and allocates bandwidth
to smaller PCIe slots, M.2, USB, audio, etc. In simplified terms, the PCH works
as a hub for peripherals that are less bandwidth-intensive.
3. PWM Fan Headers
4-pin fan headers that control the fan speed based on a configurable curve or
static percentage. PWM (Pulse-Width Modulation) works by pulsing power to
the fan at a constant rate and sending the RPM signal to the fan’s controller via
a Sense cable, rather than adjusting fan speed by increasing and decreasing
voltage. This method is preferable because it eliminates voltage-based fan stall
points. Please see Page 90 for more in-depth PWM breakdown and PWM
controls within BIOS/UEFI.
These headers also support 12v. fans. However, fan speed is based on
decreasing voltage to the fan, starting at a default of 100%/12V. When using a
12v. fan, the minimum speed will vary depending on the motor because most
fan motors require a set amount of voltage before stalling.
4. DDR4 Memory Slots
The memory slots support up to four 288-pin DDR4 DIMMs in Dual-Channel
mode. Dual-Channel mode will be enabled only upon using two or four sticks
of supported memory, according to the installation guide above; using one or
three sticks of memory will lower the board to Single-Channel mode, which
may significantly lower performance. Some Quad-Channel kits *MAY* work;
however, the kit will continue to run in Dual-Channel mode due to the
limitations of the CPU’s memory controller. 64GB of RAM is supported in a
4x16GB configuration; 32GB modules are *NOT* officially supported. At the
time of this manual’s release, this motherboard officially supports up to
4133MHz+ speeds. These speeds cannot be guaranteed, however, because
Intel®only certifies the speed of the memory controller up to 2666MHz for
Coffee Lake-S.

EVGA Z370 Classified K (134-KS-E379)
- 16 -
5. 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, PCIe (video card AND
motherboard sides), have been added to reduce the load and increase longevity
due to wiring and trace limitations.
6. 4-pin Supplemental ATX Connector
The ATX power connector on the Z370 Classified K 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.
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.
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. Supplemental PCIe 6-pin Power Connector
There is a 6-pin PCIe connector at the bottom of the motherboard (See Page 47
for more specifics to the connector itself, and associated wiring/pinouts). This
connector provides dedicated power to the PCIe x16 slots, augmenting the
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.

EVGA Z370 Classified K (134-KS-E379)
- 17 -
9. Intel®SATA 6G Ports
The Intel®Z370 PCH has a 6-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
supports NCQ, TRIM, hot swap capability (provided the proper HDD/SSD
bays/racks are installed), and RAID levels 0/1/5/10.
10. M.2 Socket 3 Key-M 80mm
M.2 is an SSD standard, which uses up to four PCIe lanes and utilizes Gen3
speeds. Most popularly paired with NVMe SSDs, this standard offers
substantially faster transfer speeds and seek time than SATA interface
standards. All M.2 devices are designed to connect via a card-bus style
connector, secured by bolting into place, and powered by the connector –rather
than a dedicated data cable and power cable.
This socket will support Key-M devices of 80mm, 60mm, and 42mm length.
Conflict: The bottom Key-M slot shares lanes with SATA port 1. As a result,
these devices are mutually exclusive and must be enabled/disabled in the BIOS.
11. M.2 Socket 1 Key-E 32mm
M.2 Key-E sockets are generally used for WiFi and Bluetooth cards. Key-E and
Key-M connectors are different, meaning that devices are not interchangeable
between sockets.
12. PCIe Slot x16/x8
PCIe x16/x8 slots are primarily for video cards. These full-length slots will
provide 8 or 16 lanes of bandwidth to a full-size card, and are backwards-
compatible with x8, x4, and x1-length cards.
Coffee Lake-S Socket 1151 processors have 16 PCIe lanes available for routing.
The 16 PCIe lanes are pulled from the CPU and shared with the x16 PCIe slot 4
(PE4). Lanes automatically switch from x16/x0 to x8/x8 when the
motherboard detects a card in slot PE4.
13. PCIe Slot x8
PCIe x16/x8 slots are primarily for video cards. These full-length slots will
provide up to 8 lanes of bandwidth to a full-size card, and are backwards
compatible with x8, x4, and x1 length cards.
This slot is limited to a maximum of 8 lanes as it shares bandwidth with the
primary PCIe x16 slot 2 (PE2). This slot is primarily recommended for

EVGA Z370 Classified K (134-KS-E379)
- 18 -
secondary video cards, such as the 2nd card in an SLI®configuration, or a PhysX
card.
* Please see the description for Physical (length) vs Electrical (lanes) on Page 21.
14. PCIe Slot x16 (x4/x2 Electrical)
PCIe x16/(x4/x2) Electrical is pulled from the PCH, rather than the CPU. This
slot would be used for PhysX in a SLI setup (at x4 speed), or any other card
that will work on a single or x4 PCIe lane. If x4 is disabled in the BIOS, this
slot should be used for cards that will work on x1 or x2 slots.
Conflict: PCIe slot 6 (PE6) shares two PCIe lanes with SATA ports 4/5. If x4
speed is disabled in the BIOS, SATA ports 4/5 will become enabled and PE6
will run at x2 speeds.
* Please see the description for Physical (length) vs Electrical (lanes) on Page 21.
15. PCIe Slot x1
PCIe x1 is the smallest form-factor PCIe card slot. They are all one lane and
are used for low-bandwidth products.
16. RGB LED Controller Header
The RBG header is a 4 pin header that allows a software based control within
windows for RGB devices via ELEET-X. Please see Page 41 for control
specifics.
17. Power Button
This is an onboard power button, and may be used in place of, or in
conjunction with, a front panel power button wired to the board.
Benching systems, or test benches before final assembly, are best served by
using the onboard power because it removes the need to wire a Power/Reset
button or cross posts with a screwdriver, which is a semi-common practice.
This button provides a safer and easier option than jumpering the Power posts.
18. Reset Button
This is an onboard system reset button, and may be used in place of, or in
conjunction with, a front panel system reset button wired to the board.
Benching systems, or test benches before final assembly, are best served by
using the onboard power because it removes the need to wire a Power/Reset
button or cross posts with a screwdriver, which is a semi-common practice.
This button provides a safer and easier option than jumpering the Power posts.

EVGA Z370 Classified K (134-KS-E379)

19. Debug LED / CPU Temp
This is a two-digit POST code reader, displaying in hexadecimal, which means
the characters available (when working as intended) are 0-9, A-F and has a cap
of 255 characters. The POST codes are listed in the troubleshooting section on
Page 131. After the system boots, it will display the temperature in Celsius.
This temperature is specifically for the CPU socket, which usually reads slightly
higher than a given CPU core. To read this temperature in Fahrenheit, take the
value in Celsius, multiply by 9/5 (or 1.8) and add 32.
20. USB 3.0 Header
The USB3.0 header is used to connect additional USB interface plugs to the
motherboard; these headers are most often used to connect the motherboard to
the chassis to enable the USB3.0 ports on the chassis. These will function
similarly to the USB3.0 ports found on the motherboard’s rear I/O hub, but
can also be used for the chassis’ front panel USB, auxiliary ports that mount in
the card slots, and certain devices that directly connect to the header.
USB 3.0 standard is 900ma @ 5V for unpowered devices. If your USB device
requires more power, it is recommended to attach a powered USB Hub.
USB 3.1 Type-A (found on the I/O Hub) shares the power limit of USB 3.0 at
900ma @ 5V. Whereas USB 3.1 Type-C (also found on the IO Hub) has a
power limit of 3000ma (3A) @ 5V.
21. USB 2.0 Headers
The USB2.0 header is used to connect additional USB interface plugs to the
motherboard; these headers are most often used to connect the motherboard to
the chassis to enable the USB2.0 ports on the chassis. These will function
similarly to the USB2.0 ports found on the motherboard’s hardwired I/O hub,
but these can also be used for the chassis’ front panel USB, auxiliary ports that
mount in the card slots, and certain devices that directly connect to the header.
USB 2.0 standard is 500ma @ 5V per port (header total is 1000ma) for
unpowered devices. If your USB device requires more power, it is
recommended to attach a powered USB Hub.
22. Front Panel Audio Connector
This motherboard header is used to plug in the audio cable included with most
PC chassis. This connector is required for audio recording and/or playback via
the audio connectors on the chassis. This header has a connector that looks
similar to the USB2.0 header and uses the standard “HD Audio” jack. Some
chassis may provide two headers: one labeled HD Audio, and one labeled

EVGA Z370 Classified K (134-KS-E379)
- 20 -
AC’97 – an AC’97 cable is not compatible with this header on the Z370
Classified K.
23. PC Speaker
This is a small mono low-fidelity speaker, which is permanently attached to the
motherboard. Its primary use is for debugging purposes. A POST beep may
indicate a successful POST or various tones for USB initialization, while other
beeps may indicate an issue during the POST process. Please see Page 129 for
more details.
24. BIOS Select Switch
This switch toggles between physical BIOS chips. The Z370 Classified K
features two BIOS chips soldered to the PCB. Each chip holds only the
settings and profiles that have been saved to the BIOS chip while active. This
allows you to swap between two physically different BIOS chips. This also
makes it substantially easier to hotflash a BIOS if needed. If instructions are
needed for hotflashing a BIOS, please contact EVGA Customer Service (Page
128 for contact info).
25. Front Panel Connectors
The Front Panel Connectors are the four main chassis connections. These
include the Power Switch, Power LED, Reset Switch, and HDD LED. The
Power and Reset switches are “Momentary Switches,” rather than “Latching
Switches,” which means the connection between two posts only needs a brief
moment to turn on the device, as opposed to requiring a constant connection.
For example, the Power and Reset switches can be triggered instantly with a
screwdriver by simultaneously touching the + and - posts.
The Power LED will power on with the system, indicating the system is on and
can blink in conjunction with CPU activity.
HDD LED will blink during access to the SATA ports; this is not activated for
M.2 SSDs.
26. CMOS Battery
The CMOS battery backup provides uninterruptable power to the BIOS/UEFI
to store all its settings; otherwise, each power on would act as if the BIOS was
just reset. These batteries typically last several years and rarely need to be
replaced.
