During AMD's Meet the Experts event, ASUS revealed more details about its ROG Crosshair X670E Extreme, a board the company revealed during Computex, but didn't show the rear I/O of. However, ASUS also unveiled the ROG Crosshair X670E Hero, a board the company hadn't shown off prior to the AMD event. Both boards will feature a pair of USB4 ports, with both ports supporting DisplayPort Alt Mode. Both boards feature a further two USB-C ports, plus seven plus USB-A ports. The Extreme features 10 Gbps and 2.5 Gbps Ethernet, whereas the Hero gets to make do with 2.5 Gbps Ethernet, although it gains an HDMI output. Both boards have a full set of audio jacks and WiFi 6E support, as well as a rear mounted clear CMOS and BIOS FlashBack button.

Taking a closer look at the Hero board, it has two PCIe x16 PCIe slots, plus a single, open-ended PCIe x1 slot. The board supports four M.2 NVMe slots for SSDs and comes with a PCIe 5.0 card for a fifth drive. It also has what appears to be six SATA ports, a front header for a 20 Gbps USB 3.2 2x2 USB-C port that also supports up to 60 W USB PD and Qualcomm Quick Charge 4+. The Hero board will be kitted out with an 18 phase power design, with the Extreme getting a 22 phase design, both with a 110 Ampere power stage. ASUS has moved its audio solution to the ALC4082 USB based audio codec and at least the Extreme will have an ESS ES9218 audio codec. ASUS is also bringing over the Q-Release solution for graphics cards to these boards, as well as the Q-Latch for M.2 SSDs.
