A notable change in this model is the repositioning of the first PCI-E x16 slot, moved down by one slot to accommodate three M.2 slots above it. While this design enhances the installation experience and CPU cooler compatibility, it may affect the heat dissipation and thickness compatibility of the graphics card. The overall impact of this design choice on performance and usability will become clearer with further testing. The ROG Strix X870E-E Gaming WiFi supports up to five M.2 slots, with at least one slot offering PCI-E 5.0 x4 support. The exact configuration and allocation specifics will be disclosed on September 30. Additionally, the M.2 slot design has been slightly upgraded for easier installation, featuring a multi-size and specification switch for the first M.2 slot.
In terms of PCI-E expansion, the motherboard includes an additional full-length PCI-E x4 slot at the bottom, supporting PCI-E 4.0. The quick-release design for the graphics card slot has also been improved. A significant enhancement in the X870 series is the native support for USB 4.0. The ROG Strix X870E-E Gaming WiFi includes two full-featured USB 4.0 ports on the rear IO, offering 40Gbps bandwidth and DP display output support. Additional connectivity includes a 20Gbps USB-C port, nine 10Gbps USB-A ports, and one 10Gbps USB-C port. The front panel also features a 20Gbps USB-C port and a 5Gbps USB 3.0 port, providing extensive expandability. The motherboard also supports WiFi-7 and includes a 5Gbps wired network interface.
