Chapter 1
S/PDIF out connector at the rear I/O
This motherboard provides convenient connectivity to external home theater audio systems
via the optical S/PDIF (SONY-PHILIPS Digital Interface) out connector at the rear I/O. The
S/PDIF transfers digital audio without converting it to analog format, maintaining the best
signal quality possible.
Gigabit LAN solution
The onboard LAN controller is an integrated Gb LAN controller. It’s enhanced with an ACPI
management function to provide efcient power management for advanced operating
systems.
8-channel high denition audio
The onboard 8-channel HD audio (High Denition Audio, previously codenamed Azalia)
CODEC enables high-quality 192KHz/24-bit audio output and jack-detect feature that
automatically detects and identies what types of peripherals are plugged into the audio I/O
jacks. Users are notied when audio devices are plugged in to the incorrect Line-in, Line-out,
and Mic port.
100% All High-quality Conductive Polymer Capacitors
This motherboard uses all high-quality conductive polymer capacitors for durability, improved
lifespan, and enhanced thermal capacity.
Complete USB 3.0 Integration
ASUS facilitates the strategic USB 3.0 accessibility for both the front and rear panel – 4
USB 3.0 ports in total. Experience the latest plug & play connectivity at speeds up to 10
times faster than USB 2.0. The P8H77-M PRO affords greater convenience to high speed
connectivity.
1.3.2 DIGI+ VRM Digital Power Design
All-new digital CPU power controls work perfectly together to match digital power signal
(SVID) requests from the CPU, with ultra-fast sensing and response efciently delivering
precision power. Accurate delivery reduces waste, and provides more stable CPU Vcore
voltages. Users can adjust CPU PWM voltages and frequencies for various overclocking
scenarios, with accurate input through UEFI BIOS tuning or the exclusive ASUS interface.
This proprietary design increases overclocking headroom to push performance to its full
potential.
ASUS EPU
Energy Efciency All Around
Tap into the world’s rst real-time PC power saving chip through a simple onboard switch or
AI Suite II utility. Get total system-wide energy optimization by automatically detecting current
PC loadings and intelligently moderating power consumption. This also reduces fan noise
and extends component longevity.
