The ROG Maximus IX Extreme motherboard is ready for your Z270 dream machine

Article Tags:

First unveiled at the Consumer Electronics Show in January, the pinnacle of Intel Z270 motherboards is finally here. The ROG Maximus IX Extreme was designed for dream rigs that push the limits of style and performance, and it truly lives up to its name. The board chills critical components with an integrated monoblock primed for ornate plumbing and aggressive overclocking. The refined aesthetics and versatile RGB lighting elevate the look of any system, while ROG staples like upgraded audio, extensive connectivity, and thoughtful touches ensure a premium experience that lives up to the looks.

Custom liquid cooling or bust

If you want to build a showcase rig that catches the eyes of discerning gamers and enthusiasts who appreciate the finer things in life, custom liquid cooling is basically required. Hardline tubing looks absolutely phenomenal when it’s done well, and systems run much cooler with liquid coursing through their veins. That’s why we worked with the experts at Bitspower to create a bespoke block that cools the CPU, VRMs, and one of the M.2 slots.

Much more than an aftermarket add-on, the block is an integral part of the motherboard. It’s infused with Aura RGB lighting and multiple sensors for monitoring fluid temperatures and flow. For peace of mind, the fittings are surrounded leak sensors that can detect escaped droplets and sound the alarm—or shut down the system automatically to protect your investment.


The Bitspower block is just one part of an extensive array of water-cooling features available for elaborate setups. For monitoring coolant elsewhere in the loop, the Extreme includes headers for an additional flow meter and temperature in/out sensors. It also has dual pump headers for driving multiple loops. Two groups of four radiator fan headers are split between the top and bottom of the board to keep your wiring tidy, and there are two traditional chassis fan headers in addition to those. Rigs with especially extreme cooling can also power three additional fans using the included ASUS Fan Extension Card. This auxiliary PCB expands support for temperature probes, as well, allowing you to attach as many as four to the Maximus IX Extreme.

The headers and sensors are all linked to our critically acclaimed FanXpert 4 software and UEFI. Automated tuners optimize an entire system’s cooling with just a few clicks, while extensive manual controls let experts hone their fan profiles to perfection. New for this generation, the Maximus IX Extreme and other ROG Z270 motherboards improve cooling for gamers by allowing fans to react to changes in the GPU temperature on select graphics cards. And, to ensure failsafe operation for a wide range of workloads, they can react to the hottest in a group of multiple temperature sensors. No other motherboard matches the Extreme’s comprehensive cooling management.


Next-level styling that stands out

Our designers drew from a monochrome palette to make the Maximus IX Extreme adaptable to any color scheme. The board looks fantastic, and Aura RGB lighting supplies a full spectrum of colors and multiple effects that let you define your own look—and change it at will. LEDs illuminate the monoblock, I/O cover, and PCH heatsink. Since the most dramatic system lighting is obtained with off-the-shelf RGB strips, the Extreme features dual headers that can drive two meters of lighting each.

Lighting is mostly a visual flourish, but the cosmetic effects are balanced by functional ones that track with audio output and system temperatures. Aura Sync extends control beyond the motherboard and to other system components, like select ROG graphics cards and peripherals, plus some third-party components that are part of our ROG Certified program. With the ability to carefully control and harmonize RGB LEDs across an entire system, the Maximus IX Extreme has everything your machine needs to stand out.

While glowing LEDs can be a bit brash, the Extreme also has subtler pieces of flair. The I/O shield is fully integrated for a streamlined look and smoother installation, the PCB edges are coated with copper for extra glint and better EMI protection, the 3.5-mm audio jacks have color-coded backlighting for easy identification, and the 24-pin power connector faces the edge of the board for cleaner cable routing.

Premium features from top to bottom

The Maximus IX Extreme is loaded with all the premiere features you’d expect from our top Z270 motherboard. To support the weight of high-end graphics cards with heavy coolers, we reinforce the main PCI Express x16 SafeSlots and anchored them more securely to the board. This strengthening improves durability, and it’s not just for graphics. The Extreme’s SafeDIMM slots employ a similar technique for memory.

The onboard SupremeFX audio combines an S1220 codec, ESS Sabre DAC, and Texas Instruments op-amp to deliver exceptional sound with a range of speakers and headsets. Thanks to a 120-dB signal-to-noise ratio, the line-out produces pristine audio for games, movies, and music. The line-in’s 113-dB SNR keeps your input clean for streaming and other recording. Like with the rest of our new ROG motherboards, you can easily route audio streams to different outputs using Sonic Studio III, and map in-game audio to a visible hub with Sonic Radar III.

A full complement of connectivity rounds out the package. Networking is split between an Intel Gigabit Ethernet controller and dual-band 802.11ac Wi-Fi, so you can jack in to any network at top speed. Onboard storage includes the usual array of SATA ports along with dual M.2 slots that let you configure the latest NVMe SSDs in an ultra-fast RAID array. And there’s USB 3.1 galore, with Type-A and reversible Type-C ports for maximum compatibility, an onboard header that lets newer chassis bring 10Gbps speeds to their front panels, and Thunderbolt integration that pushes throughput to 40Gbps.

With so many features, it’s no wonder the board occupies a super-sized EATX form factor. There’s no other motherboard quite like the Maximus IX Extreme—and no better foundation for your dream Kaby Lake build.

Sonic Radar III has also been upgraded, with an evolved audio engine that processes sounds more accurately than ever to ensure that the gamer is always aware of what’s going on around them. A new on-screen arrow has been added to help pinpoint the enemy position instantly, and there’s an all-new head-up display with an in-game three-dimensional arrow for more intuitive experiences.

Comprehensive protection: Pre-mounted I/O shield, SafeSlot, SafeDIMM, and copper-plated edge

Maximus IX Extreme is one of the toughest ROG motherboards to date, loaded with multiple safeguards to keep both itself and the user protected.

ROG’s patent-pending pre-mounted I/O shield offers increased protection against electrostatic discharge of 12kV and is pre-fitted to make it easier to install the motherboard. Its sleek new design means it looks as good as it performs, while Maximus IX Extreme’s copper-plated edge both improves the motherboard’s aesthetic appeal and provides enhanced protection against electromagnetic interference (EMI).

Maximus IX Extreme also offers PC DIYers the reassurance of SafeSlot and SafeDIMM. SafeSlot is the PCIe slot reinvented by ASUS and engineered to provide superior retention and shearing resistance. Manufactured in a single step, a new insert-molding process integrates the slot with fortifying metal for an inherently stronger slot, which is then firmly anchored to the motherboard through additional solder points. SafeDIMM is the exclusive DIMM slot with a metal key-pin that increases durability compared to traditional DIMM slots.

Ultimate connectivity: Intel LAN, dual M.2, front-panel USB 3.1, 2x2 Wi-Fi and Thunderbolt 3

Maximus IX Extreme features the very latest Intel Ethernet (I219-V) for faster, smoother gaming. Intel's LAN has the double advantage of reducing CPU overhead and offering exceptionally high TCP and UDP throughput, so there’s more power for both the game and gameplay.

The new motherboard also benefits from dual PCIe 3.0 x4 M.2 slots that provide NVMe® SSD RAID support for an incredible performance boost. This enables Maximus IX Extreme users to create a RAID configuration with up to three PCIe 3.0 storage devices via two M.2 slots and the PCH-side PCIe x16 slot to enjoy the fastest data-transfer speeds on the 7th Gen Intel Core platform.

USB-C is the latest USB connector technology, and Maximus IX Extreme allows users to put it right where they need it with an onboard USB 3.1 front-panel connector. This is powered by an ASM 2142 USB 3.1 controller running at PCIe 3.0 x2 bandwidth to maximize data-transfer speeds. The motherboard also supports Thunderbolt 3, for transfers of up to 40Gbps for four times (4X) the data speeds of USB 3.1 and twice (2X) the video bandwidth.

Maximus IX Extreme is also equipped with next-level 802.11ac Wi-Fi with 2x2 dual-band 2.4/5GHz antennas for up to 867Mbps transfer speeds — and the very latest MU-MIMO technology to ensure that every connected use experiences the best wireless and online speeds.
