Question MBs with Z590 and PCIe 4.0 1x8+3x4 configuration?

[erson]

Does any other motherboard than Asus Prime Z590-A support 1x8+3x4 with 3 PCIe slots and one M.2?

Thanks!

I count only 20 lanes..
I don't see why any Z590 boards can not do this, given you have enough physical pci-e slots.

What board are you looking at that you want to know for sure?

All the other Z590 motherboards I've looked at splits PCIe 4.0 over two PCIe x16 slots and the third x16 is always PCIe 3.0 (usually x4) from the chipset. That Asus board I mentioned is the only one I've found so far that splits PCIe 4.0 to x8, x4, x4 over three x16 slots. And it also has a PCIe 3.0 x4 slots from the chipset. And all Z590 obviously have one (some two) PCIe 4.0 x4 M.2.

So I'm just wondering if someone else has found a motherboard with three PCIe slots that all use PCIe 4.0 in the x8, x4, x4 configuration.
