Hello
@Rag,
Let's look at the PCI lane requirements for these cards:
- Video card -- either 8 or 16
- HighPoint RAID -- does your card need 8 lanes?
- Titan Ridge -- 4 lanes
- Fenvi -- 1 lane
The only reasonable solution would be a motherboard with built-in Thunderbolt because there aren't any Z690 boards with 4 PCIe slots (not counting any high-end desktop systems or HEDTs).
Built-in Thunderbolt on Z690 will always be Maple Ridge (JHL 8540). This means
no Thunderbolt bus unless you run Big Sur (only) on an Asus Z690 board. If your Thunderbolt devices work currently
without Thunderbolt bus, then they should work on Maple Ridge as well --
but there is no guarantee about reliability. Some Thunderbolt devices work very well on Maple Ridge, and others don't. It's case by case.
