Maximus XII contains high-grade components. This ensures the motherboard’s lifespan because it can handle most of the latest-generation Intel processors which usually demands more power.

With that, ASUS allows overclocking and more firepower granting you to run your computer at higher and longer speeds. Due to modern CPU architectures, motherboards require better solutions for handling such demands. 

From there, several functions were made to support this cause such as power-saving mode, lower-power mode to full load instantly. These types of modes help the user regulate how much output is coming in and out of the motherboard. 

Like many other components, the main enemy for PC hardware alike is heating. Heat is one of the most consistent factors that damage the interior parts. With this in mind, ASUS brings forth several solutions. 

Maximus XII is fully equipped to bring out higher performances with lower temperatures. They feature premium components that can withstand the pressures of power and heat. It contains multiple fan headers that are used to supply power to the fan.

Having multiple fan headers means that you can add more fans than the common motherboard would allow. With the fan expansion card, you can have as many fans needed for various purposes. 

Other than fans, Maximus XII employs chipset heatsinks that directly balance the surface area and mass of the components to help regulate the temperature. Even with the overclock, the heatsinks will do its job to contain the heat levels. 

We all have our personal preferences when it comes to customising how our PC would run. This is prominent in the ASUS ROG Maximus XII Extreme. 

ROG provides various tools that help optimise your system easily. If you want complete control, the UEFI BIOS offers further customisation options so you can reconfigure every spot in your system.

With all this in play, ASUS has worked tirelessly to bring their ideal motherboard into fruition. 

Now let’s check on its key features. 

Key Features of the ASUS ROG Maximus XII Extreme

Other than looking at its architecture, we have to see what features this product has in our ASUS ROG Maximus XII Extreme review. 

ASUS Optimem III

Overclocking is common among gamers to maximise the power of their computers. With the ASUS Optimem III, you can run at higher frequencies. You may opt to reconfigure memory between higher frequency settings or low latency settings. 

Optimem III also enables running your PC at a maximum frequency, unlike other motherboards which will trade off the frequency for capacity. 

With this in mind, you can expect to go beyond the limit and play at a higher level. 

Power Solution

Due to the demands for more power, ASUS has worked to meet this issue head-on. ASUS brings in the conventional phase-doubled, which overcomes most components’ power handling capabilities and reduces voltage ripple. 

However, most processors today have more cores and threads than the ones that came before them. They can even compute dense workloads at highly efficient speeds. With that, a re-evaluation of power and design was necessary as phase-doublers add more to the problem.

Fortunately, Maximus XII uses teamed power stages that help deliver high bursts of current per phase while maintaining the phase-doubled design’s thermal performances. 

We can see here that ASUS has done well to adjust to the everchanging pace that comes with innovation. Better processors mean that there need to be better motherboards too. 

TurboV Processing Unit

TPU, also known as TurboV Processing Unit, is an excellent micro-controller that grants an array of system-tuning features. It includes the ability to fine-tune voltages, stats, monitor systems and adjust overclocking parameters. 

With this, it becomes easier to tweak your PC configurations to the tiniest of details. 

Energy Processing Unit

EPU is an energy processing unit that controls system-wide power savings. It automatically optimises the power consumption of your PC as well as the savings in Away mode.

Away mode is an intelligent setting that allows an immense power-saving condition. This is done by shutting off I/O controllers that are unused. 

Digital Power Controls

Using the Digi+ VRM, it delivers real-time control over the voltage droop. It allows switching frequency and power-efficiency settings. With this, you may even fine-tune the CPU voltage. 


Our ASUS ROG Maximus XII Extreme offers advanced connections which include the WiFi 6 and dual Ethernet with Intel 2.5G Ethernet and 10G port. This eliminates bottlenecks within the motherboard. 

Thanks to that, one can enjoy smooth online and LAN gameplay. Additionally, the M.2 maximises one’s SSD’s speed to grant faster load times, making your sessions much quicker. 


Other than power and efficiency, style is an important factor when choosing a component that fits your criteria. With ASUS ROG Maximus XII Extreme, they provide extensive customisation options to let you design a system that looks and speaks like you. 

Aura sync is one of the style features they provide that offer comprehensive aesthetics with control and compatibility. This makes it so much easier because you can just sync your colour patterns to your other devices. 

Aside from colour patterns, there are also many different light modes to choose from. These patterns can be customised to fit how you may want them to look. 


ASUS ROG Maximus XII Extreme features more cooling options than ever before. With multiple headers, each can set to a monitor and activate to three user-friendly thermal sensors. This is optimally used for heavy workload application cooling. 

Every onboard header helps auto-detect the heat levels of the PWM or DC fans. With that, it becomes more manageable for you and your PC. 

It also comes with a dual water-temperature header and a flow-rate header that feeds information directly to the AI Suite utility. 

This allows you to track the coolant temperature and flow rate of the loop. This comes handy when paired with a liquid cooler. 

Overall, ASUS has become a force to be reckoned with when it comes to innovation in their products. They are key players in the gaming industry that help determine quality and efficiency.
