Will B350 board able to support all these device's PCIe lanes

[Wills_1111]

Hi guys:

I plan to built a new system and I am wondering if the B350 will have enough PIC-E lanes to support the following devices or I should go for X370 board here.

Here are the list of the components I will have for my new system..
3 STAT HDDs, 1 STAT BD-DVD burner, 2 SATA SSD from my old box.
Also I am thinking of getting 1 new M.2 SSD here, plus a 1080 graphic card, will B350 have enough PICE lanes to support all these device, or I should go for X370.

Many thanks in advance for your helps.

It actually depends on the specific B350 model you will get.

So, to sum up, you need a motherboard with 6x SATA (for your 3 HDDs + 1 ODD + 2 SSDs) and at least 1x M.2 socket.

There are about ~10x available B350 mobos that have the above number of ports, these are:

B350 mobos with 6x SATA ports and 1x M.2 socket:
Asus Prime B350M-A (https://www.asus.com/Motherboards/PRIME-B350M-A/)
Asus Prime B350-Plus (https://www.asus.com/us/Motherboards/PRIME-B350-PLUS/)
Asus ROG Strix B350-F Gaming (https://www.asus.com/Motherboards/ROG-STRIX-B350-F-GAMING/)
Gigabyte GA-AB350-Gaming (http://www.gigabyte.us/Motherboard/GA-AB350-Gaming-rev-10#kf)
Gigabyte GA-AB350-Gaming 3 (http://www.gigabyte.us/Motherboard/GA-AB350-Gaming-3-rev-10#kf)
Gigabyte GA-AB350M-Gaming 3 (http://www.gigabyte.us/Motherboard/GA-AB350M-Gaming-3-rev-10#kf)
Gigabyte GA-AB350M-D3H (http://www.gigabyte.us/Motherboard/GA-AB350M-D3H-rev-10#kf)
Gigabyte GA-AB350M-HD3 (http://www.gigabyte.us/Motherboard/GA-AB350M-HD3-rev-10#kf)

B350 mobos with 6x SATA ports and 2x M.2 sockets:
Asrock AB350 Pro4 (http://www.asrock.com/mb/AMD/AB350%20Pro4/)
Asrock Fatal1ty AB350 Gaming K4 (http://www.asrock.com/MB/AMD/Fatal1ty%20AB350%20Gaming%20K4/index.asp)

As to lane-sharing / disabling between the SATA and M.2 sockets, all of the B350 motherboards having just 1x M.2 socket, in one way or another, will disable certain SATA ports (usually 2x SATA ports).

On the other hand, the B350 motherboards having 2x M.2 sockets will allow you to use one of the specific M.2 socket (in PCIe x4-mode, which only disables the 2nd PCIe x16 slot running in x4 mode) and still have all 6x SATA ports enabled.

So, you don't need to get an X370 motherboard as the two Asrock motherboards above (the Asrock AB350 Pro4 and the Asrock Fatal1ty AB350 Gaming K4) would fit your requirements.

Note that in the Asrock mobos with two M.2 sockets, the socket M2_1 only runs in PCIe3.0 x4 speeds (not SATA) and disables the 2nd PCIe x16 slot (the one running in x4, not the x16 top slot for the GPU). Using the M2_1 socket does not disable any of the 6x SATA ports. The socket M2_2 only runs in SATAIII speeds (not PCIe) and disables one SATA port (the SATA3_3).

Thanks for the info, I check the spec from your link and still confused.
Ryzen has different PCI-E lanes thing than the Intel, right?
I saw the Intel H270 has 20 PCIE lanes, and Z270 has 24 lanes, and base from the Ryzen chipset, it only have a few of them and mostly the PCI-E 3.0 are from the CPU.

You're confusing things here mate .
Sata drives do not use pci express lanes in any way ,shape or form.
Any board with 6x sata ports will run all your drives & a 1080 no issue.

If you want to add an m2 ssd drive it has to be an nvme based one not sata based.

The 2 asrock b350 boards already mentioned are your best bang for buck options .

RyZen has 24 PCI-e lanes from the CPU

20 are for you to use, and 4 are dedicated to the chipset and cant be used for anything else.

so 16 for the first PCI-e x16 slot
or 8 for the first PCI-e x16 slot and 8 for the 2nd one if you plug anything into that second slot.
then 4 for the M.2 drive port.

everything else gets its PCI-e lanes from the chipset, the chipset can supply upto 8 I think it is, but run at 2.0 specs instead of 3.0 due to the DMI limitation.

Sorry this is based on X370 chipsets and any B350 chipset with 3 x PCI-e x16 slots, the way they label them is the shielded slots run off the CPU, the non shielded slots run off the chipset, the ASUS Strix B350-f is a prime example of this setup.

As for B350:

The PCIe 3.0 16x comes from the CPU, the M.2 SSD gets PCIe 3.0 4x from the CPU, thats your 20 gone.
The other 16x gets PCIe 2.0 4x from the B350 chipset, the other 1x are also from chipset.
