USB Audio Power is a breakthrough in Home Theater Entertainment audio quality. Using an unique design, the USB ports onboard provide a TRUE 5V signal that doesn’t drop when more devices are connected.This simply means better signal quality over USB, especially for devices that rely on a perfect signal, like USB DAC’s as they rely on a perfect transmission of audio bits from the motherboard to the DAC. This also means that external low-noise power supplies are no longer essential for better audio quality as USB Audio Power is able to deliver an optimum USB signal.

Military Class 4 components

Military Class 4 is the next step in high quality components. The Hi-c Cap, Super Ferrite Choke and Solid CAPs will make sure that your PC runs more stable under extreme conditions.

Hi-c CAP

A Hi-c CAP is a very small, but super-efficient capacitor. Besides ensuring enough spacing around a CPU socket to install large coolers, it also allows for 93% energy efficiency. Thanks to Hi-c CAP`s MSI mainboards are the most energy efficient in the market.

Dark CAP

With their aluminum core design, Dark CAP's have been a staple in high-end design motherboard designs and provides lower Equivalent Series Resistance (ESR) as well as its over-10-year lifespan.

Super Ferrite Choke

Super Ferrite Choke uses a Ferrite core that is Super-Permeable. This allows the Super Ferrite Choke to run at a 35 degree Celsius lower temperature, have a 30% higher current capacity, a 20% improvement in power efficiency and better overclocking power stability.

Military Class essentials

The core of Military Class 4 is based on the essentials which increase your stability in the toughest conditions.
The humidity protection and high temperature protection ensure your system can survive each environment, no matter how harsh. The new structure of the PCB limits EMI radiation.
On top of that the all the connectors have ESD protection in order to prevent short circuit.
