EVGA Z270 FTW – K (132-KS-E277)
This socket will support Key-M devices of 110mm, 80mm, 60mm, and 42mm
length.
13. M.2 Socket 1 Key-E 32mm
M.2 Key-E is largely used for WiFi and Bluetooth cards. Key-E and Key-M
connectors are different, meaning that devices are not interchangeable between
sockets.
Conflict: Key-E shares one PCI-E lane with PCI-E slot 3 (PE3). As a result,
these devices are mutually exclusive and must be enabled/disabled in the
14. PCI-E Slot x16/x8
PCI-E x16/x8 slots are primarily for video cards. These full-length slots will
provide 8 or 16 lanes of bandwidth to a full-size card, and are backwards-
compatible with x8, x4, and x1-length cards.
Skylake and Kaby Lake-S Socket 1151 processors have 16 PCI-E lanes available
for routing.
The 16 PCI-E lanes are pulled from the CPU and shared with the x16 PCI-E
slot 4 (PE4). Lanes automatically switch from x16/x0 to x8/x8 when the
motherboard detects a card in slot PE4.
15. PCI-E Slot x8
PCI-E x16/x8 slots are primarily for video cards. These full-length slots will
provide up to 8 lanes of bandwidth to a full-size card, and are backwards
compatible with x8, x4, and x1 length cards.
This slot is limited to a maximum of 8 lanes as it shares bandwidth with the
primary PCI-E x16 slot 2 (PE2). This slot is primarily recommended for
secondary video cards, such as the 2
card.

16. PCI-E Slot x16 (x1 Electrical)
PCI-E x16/x1 Electrical is pulled from the PCH, rather than the CPU. This
slot would be used for PhysX in an SLI setup, or any other card that will work
on a single PCI-E lane.
