Motherboards that support 2 triple slot gpus at x8

[Maralc]

Can someone confirm which motherboards can support 3 or 2 triple slot GPUs at x8+x8+x8 or x8+x8?

I saw the ws w680-ace can support x8+x8+x4.

Wondering for example if the prime z790-p can support dual triple slot gpus in x8+x8?

Thanks in advance!

Hello, @Maralc 

Taking the PRIME Z790-P as an example, you can confirm the recommended slots, corresponding operating speeds, and bandwidth configurations when installing three graphics cards on page 1-7 of the user manual.

If you have three PCIeX16 slots and require configurations, we recommend visiting the official website > motherboard, selecting "3" in the PCIeX16 Slots filter on the left, and choosing the specific model.

Then, navigate to the support page for that model and further confirm the details in the user manual located under "Manual & Document."

Thank you.
