X570 PCIe Lane Help

[Light1984]

I've tried google and searching here but can't really understand the breakout in the image below for my Asus Crosshair Dark Hero VIII. Currently I have a 3090 installed and one WD SN850X in the M.2_1 slot. I have two WD Blue 2.6" SSDs attached to SATA ports. I have W11 on the NVME of course and I run games off one of the WD Blues and the other is just a back up. Do I have enough PCIe direct to CPU lanes to move my games onto a new NVME drive installed in M.2_2 or will that drop my 3090 to 8x?

Are your WD Blue 2.6" SSDs SATA, or U.3 drives?

It's in the manual. Don't take this the wrong way, but RTFM. Nothing happens when you populate the second NVME slot, it doesn't disable SATA ports and it doesn't change bandwidth on your PCIe x16 slot. The only way you drop the primary x16 slot to x8 is if you populate PCIEX16_2 which then drops to x8 as well.
