GIGABYTE Digital Power Engine

GIGABYTE Ultra Durable motherboards take advantage of an exclusive Digital PWM controller array, to deliver maximum and stable power to latest processors. Using digital controllers means that more precise power delivery to the motherboard's most power hungry and energy sensitive components is possible. This Digital Power system, with Precise Auto Voltage Compensation to make real-time adjustments and deliver a steady flow of power to the system, no matter the loading. This all new, digital power system provides enthusiast users with exceptional control over the overclocking potential of their GIGABYTE motherboard.

Realtek ALC1150 115dB SNR HD Audio with Built-in Rear Audio Amplifier

115dB SNR HD Audio 
The Realtek ALC1150 is a high-performance multi-channel High Definition Audio Codec that delivers an exceptional audio listening experience with up to 115dB SNR, ensuring users get the best possible audio quality from their PC.
The ALC1150 provides ten DAC channels that simultaneously support 7.1-channel sound playback, plus 2 channels of independent stereo sound output (multiple streaming) through the front panel stereo outputs. Two stereo ADCs are integrated and can support a microphone array with Acoustic Echo Cancellation (AEC), Beam Forming (BF), and Noise Suppression (NS) technologies. The ALC1150 incorporates Realtek proprietary converter technology to achieve Front differential output 115dB Signal-to-Noise ratio (SNR) playback (DAC) quality and 104dB SNR recording (ADC) quality.

High Quality Audio Capacitors

GIGABYTE Ultra Durable™ motherboards use high quality Nippon Chemicon ARE series audio capacitors. These professional audio capacitors deliver the highest quality sound resolution and sound expansion to create the most realistic sound effects for user experience.

Dedicated Audio Hardware Zone

+ Separation on the PCB layer protects the board's sensitive analog audio components.
+ Separate analog and digital ground to protect against Electromagnetic Interference (EMI).

eSATA Ports for easy data manipulation on external devices

Featuring with two external SATA (eSATA) ports on rear panel, it provides smart setup and hot-plug functionality allowing easier data backup and content manipulation on external storage devices.

2x Copper PCB Design (2 oz Copper PCB)

GIGABYTE's exclusive 2X Copper PCBs design provides sufficient power trace paths between components to handle greater than normal power loads and to remove heat from the critical CPU power delivery area. This is essential to ensure the motherboard is able to handle the increased power loading that is necessary when overclocking.
