Intel Z390 Motherboard Overview: 50+ Motherboards Analyzed

ASUS ROG Maximus XI Formula

Another high-end board on the Z390 chipset from ASUS is the ROG Maximus XI Formula which has a similar rear panel cover as the Maximus XI Code along with what looks to be a near identical PCIe slot layout. Other similarities stretch to the use of a PCB cover which looks to have a little more flair and more RGB than the Code, but from a quick glance, the entirety of what's visible PCB wise looks to be identical to the ROG Maximus XI Code; this is not necessarily a bad thing. The biggest difference and impressive inclusion on the Formula over the Code is the EKWB power delivery water block which allows enthusiasts to hook it up to custom water cooling loops for even lower VRM temps; perfect for users to overclock their processors and NOT have to worry about the quality of the power delivery heatsinks.

The Maximus XI Formula keeps the same power and reset buttons with a LED debug in the top right corner. There are four RAM slots with support for DDR4-4400 with a maximum capacity of up to 64 GB in total. Built-in into the board is a pair of PCIe 3.0 x4 M.2 slots (one with SATA support and one without) which feature a pair of heatsinks which amalgamate into the boards overall aesthetic. Also present is a total of six SATA ports with support for RAID 0, 1, 5 and 10 arrays. 

The board has three full-length PCIe 3.0 slots which allow for two-way SLI and three-way CrossFire multi-graphics card support at x16/x0/x4 and x8/x8/x4 respectively much like the majority of the Maximus XI boards including the Hero, Hero (Wi-Fi) and Code. This also stretches to the onboard audio and networking with a Supreme-FX S1220 8-channel HD audio codec and a single Intel I219V Gigabit NIC on the rear panel.

With a host of quality connections integrated, there's dual LAN with one port being powered by an Aquantia AC111C 5 G NIC and the second by an Intel I219V Gigabit controller. Wireless networking is provided by a Wave 2 2T2R 802.11ac Wi-Fi adapter and a single HDMI 1.4b video output. The same pair of buttons consisting of a BIOS Flashback and clear CMOS is featured much like the Code, and the onboard audio is controlled by a gaming-focused SupremeFX S1220A HD audio codec. Last but not least is USB support, with three USB 3.1 Gen2 Type-A ports, a single USB 3.1 Gen2 Type-A port and a hefty six USB 3.0 Type-A ports completing a packed rear IO.

The ASUS ROG Maximus XI Formula has an unknown price as of yet, but is one of the top ASUS Z390 boards at launch with a clear focus on gaming based features and enthusiast grade components such as the EKWB made power delivery heatsink. The Formula is primarily targeted at gamers and enthusiasts with overclocking as a focus and the inclusion of 5 Gigabit LAN sets this board apart from the most of the Maximus XI range.
