Yes, as that is what I use for connectivity.

Does this support 9th gen processors?

No it does not, this supports the Z790 chipset and LGA1700 socket, 9th gen intel uses the LGA 1151 socket and 300-series motherboard chipsets (e.g. Z390, B360, etc.)

Is this compatible with DDR4?

This one is not. There is another board that says "DDR4" in the title.

Do you think a i9 13900k would be good on this?

I would think so. I use an i7-13700K without issue.

Does the MB GIGABYTE | Z790 UD AC R support RGB lighting?

Yes, the GIGABYTE Z790 UD AC motherboard supports RGB lighting.

why it does not recogonize my old ssd M2 drive?

The GIGABYTE Z790 UD AC motherboard has specific compatibility for M.2 SSDs. It supports PCIe 4.0 x4/x2 M.2 SSDs and type 22110/2280 M.2 connectors. If your old M.2 SSD does not meet these specifications, it may not be recognized by the motherboard.

why it does nit recogonize my old SSD M2 drive?

The motherboard supports the following M.2 connectors: 1 x M.2 connector (Socket 3, M key, type 22110/2280 PCIe 4.0 x4/x2 SSD support) from the CPU and 2 x M.2 connectors (Socket 3, M key, type 2280 PCIe 4.0 x4/x2 SSD support) from the chipset. Please ensure your old SSD M.2 drive is compatible with these specifications.

Do you think i could run an i9 13900k on this or would that not work idealy?

I would think that it would run great on this board as I use an i7-13700k with it.
