8700k 16 PCIe lanes???

Hey peeps, wondering if you guys can help me out...

 

So I was planning on a new build:

-i7 8700k

-Asus Maximus Hero X Z370

-Samsung 960 EVO 250GB M.2 NVMe 

 

Upgrading from an i7 3930k, already have a 1070 Strix GPU. 

Researching the 8700k, I discover that it only has 16 PCIe lanes. Would having my GPU and an NVMe m.2 (utilises PCIe x4) cause any problems?

If not/so could you explain how and why? Not completely in the know regarding PCIe lanes

 

Thanks in advance!!!

I am not for sure on this, but I reckon the Nvme SSD's lanes are connected to the chip set, not the CPU.

It shouldn't, and depending on if the m.2 is connected to the PCH or CPU directly will change if it pulls any lanes from the Graphics card.  This will vary from motherboard to motherboard.

More PCIe Lanes on core i9s 

I don't think an i-9 is in his price range.

Yeah I see that the Z370 chipset has 24 PCIe lanes, just don't know if ill be handicapping myself in anyway with this planned setup

I'm definitely more of a gamer than a content creator, basic web design and video editing so not looking into that kind of platform. Thanks for replying btw

Your chipset also provides some PCI lanes, check the manual of the motherboard you're thinking about and it should have a section on what ports use CPU PCI lanes and which uses chipset (often abbreviated as PCH) lanes.

If you're worried about PCIe lanes then have a look at a 6800K and an old X99 board. You can get 28 PCIe lanes for about 300 bucks, less if you go used.

Thanks guys appreciating the help. Definitely more interested in the 8700k Z370 platform. Just this one aspect concerns me but if your right in that the NVMe m.2 uses up chipset PCIe lanes and not the CPU's then this will be perfect.

Haha! Yeah trying to figure that out now, it's a Samsung 960 EVO NVMe m.2 I'm looking into

It will 100% not be an issue.  Your m.2 drive will use the chipset lanes and will not be handicapped at all.  Your GPU can run at 16x.  Even if for some reason it couldn't (which it can) 8x is more than enough for your GPU.  There is no way a 1070 can saturate 8x PCIe 3.0.

This is perfect thank you! Can continue planning the build now! Cheers fellas
