ASRock Z270 Taichi PCI-E setup

I want to have two PCI-E devices: 1) Graphic Card - x16 PCI-E  2) SSD disk - x4 PCI-E Is this possible ob Z270 Taichi? If yes, then which slots?  I mean - if I want to have graphic card in PCIE2 slot with x16 speed - could I use any other PCIE slot at x4 speed same time? Thanks!!

The specifications can be a bit confusing about the PCIe slots, as you know. What is possible is limited by the PCIe lanes provided by the Intel CPU used, and the Z270 Kaby Lake chipset. That system has some improvements over the previous Z170 Skylake chipset.

From the Z270 Taichi specifications:

4 x PCI Express 3.0 x16 Slots (PCIE2/PCIE3/PCIE4/PCIE5: single at x16 (PCIE2); dual at x8 (PCIE2) / x8 (PCIE4); triple at x8 (PCIE2) / x4 (PCIE4) / x4 (PCIE5). PCIE3: x4 mode )

It would be useful to know which PCIe x4 SSD you are using. Is it M.2 in an adapter card, or a PCIe slot AIC SSD like the Intel 750?

You can have a video card in the PCIE2 slot running at PCIe 3.0 x16, and a PCIe 3.0 x4 SSD in the PCIE3 slot running at PCIe 3.0 x4 at the same time.

This board also has three M.2 slots running at PCIe 3.0 x4, but shares resources with the Intel SATA III ports.
