[SOLVED] I’m getting the 5900x but....

[NoLongerHuman]

So I’m going with amd for this build my last build had a 6700k. I want to have all nvme storage this is purely a gaming rig but I have 3 Nvme m.2 as well as a 3090 ftw3. Will the 5900x have enough pcie 4.0 lanes to support all this? I guess I’m a little confused about how pcie lanes work because I know that the chipset has some as well as the cpu itself will I still get 16x on my gpu if I populate all the m.2 slots with pcie 4.0 storage?

here’s my build

If the Ryzen 5900X is similar to the 3900X, then it should have up to 24 PCIe lanes. The 3090 itself will take up to 16 lanes and that motherboard only allows 1 M.2 to connect directly to the CPU which uses another 4. So essentially 20 lanes already used up. The other 2 m.2 slots go through the chipset, which should help solve the lane issue. So all in all it should work.

Though please refer to your manual to further see if your setup will work:

Also not that the first two PCIe slots can handle both PCIe and SATA NVMe's while the third slot is PCIe NVMe only.

Wow thanks that’s really helpful
