Can I use a m.2 or am I out of lanes?

[FifteenOnes]

Do m.2 drives use my pci lanes? I am really confused because I have a 750 series ssd, a wifi card, and my gpu occupying my 16 lanes. Would a m.2 still work? (the pc parts mentioned below are out of date, I have just never changed them)

You can get a Extension for a PCIE to support a M.2 SSD... Directly into the Lane, is a certain no

Please explain, I'm new to this

NVMe M.2 drives will use lanes provided by the chipset. It will have no affect on your GPU's lanes or performance. Even if it did, it would just knock it down to 8x which is enough for any GPU.

Intel chipsets provide 16+ lanes (depending on the chipset itself) and will provide all you need for the M.2.

m.2 connectors are made up of two parts ,  one SATA connection and up to 4 pci-e lanes (two sections each with two pci-e lanes).

 

Depending on the SSD controller, your SSD may use the SATA part of the connector (in which case one of the SATA ports on your motherboard may become inactive/disabled)  or the SSD may use pci-e lanes in the connector.

Some SSD drives can use both (and then sometimes from the BIOS you can force them to use the slower SATA part of the m.2 connector if you want to)

 

Also, some motherboards allow you to use all four pci-e lanes in the m.2 connector, or you can configure the m.2 connector to use only 2 pci-e lanes, leaving two lanes available for pci-e x1 slots on the motherboard, or redirecting the two lanes to enable more sata or usb ports on the motherboard (depends on chipset).

 

You should look up the manual for your motherboard, it really depends from motherboard to motherboard, and how your board behaves also depends on what chipset you have on the motherboard.

My mother board is the Asus z170-a

The M.2 slot gets PCIe lanes from the Z170 chipset, leaving all the PCIe lanes from the CPU available to the graphics card.

People these days are incapable of helping themselves.
