EVGA Z790 DARK K|NGP|N (121-RL-E799)
11. ASMedia SATA 6Gb/s Ports
This ASM1061 is a secondary 2-port SATA 6GB/s controller with legacy
support for older operating systems (See Page 50 for more information about
the connectors).
12. M.2 Socket 3 Key-M 110mm (M.2_1, M.2_2, and M.2_3)
M.2 is an SSD form factor standard, which uses up to four PCIe lanes and
utilizes up to Gen4 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 – rather than a dedicated data cable and power cable.
This slot supports device lengths of 110mm, 80mm, and 42mm.
13. PCIe Slot x16/x8*
Raptor Lake-S and Alder Lake-S processors have 20 PCIe lanes available for
routing. Unique to the Z790 DARK K|NGP|N, the PCIe Gen 5 lanes will be
automatically switched between the two x16 PE1 and PE2 slots.
When a single PCIe device is installed in either PE1 or PE2, the CPU will
allocate x16 PCIe Gen 5 lanes to the slot where the device is located. If PCIe
devices are installed in both x16 slots, both lanes will operate at x8/x8 speeds.
* Please see the description for Physical (length) vs Electrical (lanes) on Page 26.
14. PCIe Slot x4*
PCIe x4 is a smaller form-factor PCIe card slot. These can be used for low-
bandwidth products, such as a PCIe SSD card, capture card, audio card, etc.
This slot is limited to a maximum of x4 Gen4 CPU lanes.
* Please see the description for Physical (length) vs Electrical (lanes) on Page 26.
15. 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.
Open-air or test bench chassis are best served by using the onboard power
because it removes the need to wire a Power/Reset button.
16. 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.
Open-air or test bench chassis are best served by using the onboard power
because it removes the need to wire a Power/Reset button.
