Question about PCIE lanes and SATA ect.

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I have an ASROCK X570 phantom gaming 4, coupled with a 5800x.  I understand that 16 lanes run straight to the gpu, 4 to the first M2 slot, and 4 to the chipset.

I am currently running 2 2.5" SSD's to 2 of the SATA ports, and also running a USB expansion card to one of the x1 slots.

My question has 2 parts: First, will i be able to run a 2nd M.2 in the 2nd M.2 slot (total: 2 M.2's, 2 2.5" SATA SSD's, and a PCIE x1 USB card)

Second, does the 2nd M.2 slot run through the chipset?  Will it affect the ability to run 2 SATA SSD's and the x1 USB card?

	The only PCIe slot that is directly connected to the CPU is the first x16 slot. The only m.2 slot that is directly connected to the CPU is the first M.2 slot. Everything else is connected through the X570 chipset. https://www.techpowerup.com/img/HMRSMmd3jbU2CVX0.jpg X570 has plenty of options. It looks like that board has fully dedicated 8 SATA ports, so they will not be affected by anything else. The only shared resource appears to be Thunderbolt expansion and the SATA portion of the second m.2 slot.
