An elegant motherboard
for a more civilized age.

The DARK rises again. Not content to merely shatter records and competition in the consumer market, the EVGA SR-3 DARK merges two extreme performance lines of EVGA motherboards to bring balance to the force with exceptional performance and engineering.

Featuring the Intel® C622 chipset, hexa-channel memory support, 23 phase power design, 16-layer PCB, dual-10GbE LAN ports, a waterblock to passively or actively cool the DARK’s VRM, and so much more, this board is packed with everything and is still compact enough to fit in a full E-ATX form factor.


EVGA continues its revolutionary design by using right-angle power connectors to improve airflow and cable management. Connect up to four 8-pin EPS connectors to provide maximum power to your Intel XEON® W-3175X CPU!


The SR-3 DARK features a pre-installed waterblock to provide maximum cooling to the chipset and VRM of the motherboard. No watercooling? No problem. The SR-3 DARK will still provide sufficient cooling for all standard uses of the motherboard.

With the EVGA SR-3 DARK, you don't need to see its identification to
know that the next evolution of the X299 and Z390 DARK
motherboards features the latest improvements for
performance and enthusiast needs.


1. 16-Layer PCB

A 16-layer high-speed E-ATX PCBA
with gold-plated shielded edge enhances
stability for heavy loads, improved
overclocking, and durability for today's
extreme cooling hardware.

2. Highly-Efficient 24-Phase PWM

The SR-3 DARK features a 24-phase
Digital VRM (18 VCore, 1 VSA, 1 VCCIO,
4 VDDR) for the cleanest, most stable
power design to ensure that you're ready
for Intel’s 28-core XEON® W-3175X

3. 300% Higher Gold Content in CPU Socket

Higher volume of precious metal (300%
Gold) used in the Narrow 30u socket
creates lower contact resistance, resulting
in better power delivery.

4. Intel® sSATA to Mini-SAS 6Gb/s Port

The Intel® C622 PCH supports 10 SATA
6Gb/s drives, including an additional 4
ports through a mini-SAS connector
located behind the SATA Ports. The
controller also supports NCQ, TRIM, hot
swap capability, and RAID levels 0/1/5/10.

5. PCIe Disable Switches

The SR-3 DARK offers PCIe disable
switches to quickly shut off PCIe slots to
troubleshoot or restore used resources
without the need to physically uninstall hardware.

6. Triple BIOS Select Switch

Switch between up to 3 different BIOS
ROMs for overclocking, benching, 24/7 use,
or anything you can think of.

7. SW Slow Mode Switch

Changes the CPU Ratio to the minimum
CPU ratio in real-time for stability purposes
or to reduce heat/power usage between
long benching sessions.

8. ProbeIT Connectors

Attach your Digital Multimeter to the
included ProbeIT adapter and monitor all
your voltages in real-time.

9. Creative Core3D Audio

Creative 5.1 Channel Audio with output
amplifiers – the industry standard for audio

10. Safeboot Button

Pressing this button will restart the
system and launch into the BIOS at safe
setting, while keeping the same settings
when you previously left the BIOS.
Handy for those times when the board
fails to POST, but you only need to make
one or two changes to fix it!

The dedicated internal USB port on the motherboard allows you to update your motherboard BIOS even if you don't have a CPU or cannot boot into the motherboard.


Post Indicator

Multi-Function POST Indicator – Fully configurable in BIOS, these LEDs can be configured to show temperatures, voltages or cycle both in real-time


Right Angle Headers

24-pin power, both 8-pin CPU power, Fan, and Probe-It connectors – Hand-crafted design to provide clean system assembly without cable clutter.


Visual Guide / Bench Table

Every EVGA SR-3 DARK is packed with a printed PCB showing components, LEDs, PCIe lane breakdowns, and other helpful information. More importantly, this PCB with included standoffs doubles as an open-air testing or benching station, providing clearance for heaters, condensation isolation, and storage devices.


PCIe / DIMM Status LEDs

PCIe / DIMM status LEDs allow for easy system assembly and troubleshooting at a glance.

If you had any doubts before,
only at the end do you realize
the power of the dark side
of evga's motherboard lineup.
