Maximus VIII Extreme's onboard audio isn't just good — it's as good as you can get! You benefit from the best gaming-audio inputs and outputs, with special shielded designs, and a collection of carefully selected professional-grade audio components, including an ESS® ES9023P digital-to-analog converter (DAC) with Hyperstream™ technology, ultra-low-jitter clock, Nichicon capacitors, 2VRMS headphone amp, and Sonic SenseAmp that automatically detects and optimizes any headset (32-600ohms) for purest sound quality. SupremeFX 2015 also features intuitive Sonic Studio II, so you'll apply and enjoy different audio effects for perfect entertainment — plus Perfect Voice noise-cancellation technology for team conversations with total clarity!

Get your hands on OC Panel II, an intuitive system monitoring and tweaking in two modes. For both, a clear 2.6-inch display keeps you informed and in full control — so you can maximize the available power. OC Panel II also comes with the illuminated LED on the stunning ROG logo.

OC Panel II installs directly into a 5.25-inch drive bay to provide real-time monitoring of multiple vital parameters, including CPU temperature, ratios, base clock and fan speeds! The OC button provides instant control over overclocking, while CPU fan speeds can be adjusted to Turbo, Standard and Silent modes — super-simple controls, all at your fingertips.

OC Panel II can also be used as external overclocking console, giving easy access to multiple ROG-exclusive features including Subzero Sense, VGA Hotwire, Slow Mode and Pause Switch. You also have direct access to two PWM and two full-speed fan headers, as well as remote power and reset buttons. Extreme mode also offers easy access to the all-new Safe Boot and ReTry buttons for instant configuration testing and diagnosis

You don't need to be an expert to max out gaming performance on your Maximus VIII Extreme build's gaming performance — because 5-Way Optimization sorts all the complex settings with a click, for instant, highly-controllable performance boosts! Our exclusive technology dynamically optimizes essential aspects of your system based on real-time use, so you get superb CPU performance, everyday energy savings, ultra-stable digital power, cool and quiet fans and even networking and audio settings that are tailored for the apps that you are using. In short, 5-Way Optimization ensures that your PC is perfect for gaming, entertainment, productivity or just about anything else!

All-round energy efficiency
EPU

With the Energy Processing Unit (EPU) you'll enjoy real-time, system-wide power savings — for gaming kicks that won't cost the earth! EPU automatically detects and adjusts power consumption according to your rig's needs, so you save money without compromising the thrills. EPU will also reduce CPU wattage to a set level and deliver even more savings with Away Mode, creating an extreme energy-saving scenario that shuts down unused extra I/O controllers and reduces the graphics cards' power level. So, full power for your gameplay — and then total energy efficiency when you step away!

Cooler by design

Play quieter and cooler with advanced fan and water-pump controls for the ultimate in undisturbed gaming. With onboard thermal sensors and hardware-level 4-pin/3-pin PWM/DC mode detection, Fan Xpert 3 makes sure every fan achieves the best balance of high cooling performance and low noise, so you enjoy all the performance you demand with none of the racket!

Precise Digital Power Control

To go faster than fast you need ultra-accurate power control — so Maximus VIII Extreme motherboards are kitted out with ASUS Digi+ Power Control for maxed-out overclocking potential, enhanced system stability and superb power efficiency. Digi+ Power Control is the industry's leading digital power controller and it's fully compliant with Intel's IMVP8 specifications, for smoother, safer power.

Accelerate your favorite apps and games with automated ease

ASUS-exclusive Turbo App's intuitive tuning panel boosts multiple hardware components to maximize gaming exhilaration, overclocking your CPU, tuning your fans, prioritizing network data and optimizing audio settings — all with automated ease.
