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

All Solid Capacitors

Capacitors are the most important component for electronic product's power supply. The quality of the capacitors can impact the stability of the entire system and risk of product failure. Currently there are two types of capacitors, electrolytic capacitors and solid capacitors. Compared to electrolytic capacitors, solid capacitors have a longer lifespan, and provide a more stable power under high temperatures. More importantly, solid capacitors do not have any liquid materials inside, and thus will not suffer a leak which would infringe upon the product’s stability. With such benefits is it no wonder that solid capacitors are very important for product quality's improvement.
featurePic

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.
