The IO panel of the AROUS Z270X-Gaming 7 features a PS/2 keyboard/mouse connector, two yellow DAC-UP 2 USB 3.1 ports, a HDMI 1.4a port and Display Port. Furthermore we find three USB 3.0 ports, USB 3.0 type-C (Thunderbolt 3)  and type-A port (red), Rivets Network Killer (E2500) and Intel GbE LAN RJ-45 ports (10/100/1000 Mbit) Teaming is not supported. Finally 5 gold plated audio jacks with S/PDIF optical ports hooked up to the Creative Core 3Di audio chip.

On the above picture we can spot upper right the Creative Sound Core3Di quad core audio solution. In the center we find the TI Burr Brown OPA2134 operational amplifier (upgradable), topped by Nichicon Gold electrolytic audio capacitors. Below the front audio panel connector we find the Audio Gain Control Switch (out jack for the back panel) to switch from 2.5x (default) to 6x gain. Below we can also spot the top BIOS Switch to use the main or backup BIOS. The SB Switch below is the Dual BIOS Switch. The LED_C is ready to power a standard 5050 RGB LED strip.

All AORUS boards support up to 3 way GPU configurations, only the Gaming 9 version is certified to handle 4 graphics cards.  Three PCI Express x16 slots are equipped with the Ultra Durable PCIe Armor, a one piece stainless steel shielding to increase the strength to support heavy graphics cards. The top PCIe x16 slot runs at  x16 with one GPU installed, the second one at maximum x8 and the 3rd PCIe x16 slots runs at x4 (PCIEX4). If one installs two graphic cards, the number of PCIe lanes are divided over the two PCIe slots, so x8/x8.

• single card mode: x16 / x0 / x0 
• dual card mode: x8 / x8 / x0
• triple card mode: x8 / x8 / x4

Three PCI Express x1 slots are foreseen for other add-on cards.
