Military Class Concept The perfect trinity of quality, stability and efficiency all exist at one mainboard to meet end user expectations. The MSI Military Class series products provide the long lifespan, unparalleled quality, extreme performance and ultimate efficiency. Icy Choke Unbelievable Stability & Lower temperature!! Compared to the traditional ferrite choke, the Icy Choke provides higher power efficiency and a more stable power supply, which also fulfills power users need for idealized environment with turbo speed and low operating temperatures. Solid CAP 10 years long lifespan For providing the highest quality products, we built-in Solid CAP in the entire Military Class series. This not only makes bursting capacitors a non-issue but also ensures a dramatically extended lifetime and ultra-low ESR. M-Flash Compared to common mainboard which need extra BIOS chips, MSI’s M-Flash has a double advantage which doesn’t need extra components and secondly, all your BIOS data will be saved in the USB drive. The stored data does not only have backup and upgrade function, moreover it can also be seen as a portable BIOS chip which is actually able to boot up your PC. Features - Backup/Restore Your BIOS to/from Any USB Flash Disk - Avoid Unnecessary Repair Due to Accident Failures During The Upgrading Process - Earn more BIOS Lifespan by Reducing Unnecessary Rewriting Process APS (Active Phase Switching) Active Phase Switching, APS, technology is an intelligent design that helps to save energy on MSI’s mainboards. The underlying idea is to switch off the power supply as soon as no electricity is needed, and when the system needs more resources again, APS will automatically adjust electricity supply accordingly. APS will automatically detect your processor’s loading at any given time and save energy accordingly. This is only possible by means of a very advanced power controlling technology. Other than software-based solutions, APS technology stands out from MSI's own research. The specially developed IC chip can operate automatically depending on the demands of the power supply, which is to reduce the total power usage. Lossless 24-bit/192KHz HD Audio Onboard PC audio gets better! MSI is the first to implement the most high-end HD Audio codecs available. Don’t be fooled by other inferior audio solutions onboard (sometimes you can’t even find the driver!) Only MSI offers the Loss-less 24-bit/192KHz HD Audio function with an incredible 109 SNR dB value to provide the most clear & vivid HD audio quality and support 7.1 channels surround sound playback with a 2-channel independent stereo output (multiple streaming) through the front panel 3.5 inch phone jack. HDMI v1.3 HDMI (High-Definition Multimedia Interface) is new generation fully digital video/audio interface which can transfer 1080p Highi-Definition video and Audio output in single compact connector. By passing HDMI 1.3 certification, this product can deliver highest video, audio quality and also support HDCP protection of Blu-ray. Features - Next-Gen Multimedia Interface - Deliver Full HD Video & Audio output In Only One Cable USB Safeguard USB Safeguard can prevent mainboards and USB devices from being damaged by short-circuit and ESD (Electro-Static Discharge) with Anti-ESD chips built-into the mainboards. Additionally, the safeguard can protect against such dangers multiple times, and greatly improves product lifespan. Features - All MSI mainboards use USB Safeguard’s anti-ESD chip for thorough protection against ESD damage - USB Safeguard is protected against a short circuit and/or ESD without the need for a fuse. It also supports stand-by power supply i-Charger Mobile consumer appliances are getting more and more attention in current day fast moving life style, with smart phones and tablets almost becoming a fashion accessory. However, many ordinary personal computers cannot charge some of these devices, making it difficult to stay connected. The MSI i-Charger is a Windows resident program capable of revising the power supply mode of your USB port to become more powerful. Once your phone or tablet is connected to your USB port, the i-Charger sends a signal to initiate its charging circuit, making it a really smart and convenient charging solution for mobile computing needs. Features - Automatically Detect & Charge Your Smart Phone or Tablet - Support Microsoft Windows 98SE/ME/2000/XP/Vista/7 32Bit Live Update 5 MSI Live Update 5 is a powerful and useful application for updating the latest BIOS and Drivers, saving you time and lowers the risk of updating. End-users can install and run the Live Update 5 software on their computers with the companion CD or downloading the app from the MSI website. Features - Automatically Detect the BIOS/Driver/VGA/Utility Update - Support Microsoft Windows XP/Vista/7 32/64bit HTPC Ready With such diversity of display outputs, you are able to choose and upgrade display devices then build up your own home theater.
