Compared to common mainboard which need extra BIOS chips, MSIs M-Flash has a double advantage which doesnt need extra components & secondly, all your BIOS data will be saved in the USB (Universal Serial Bus) drive. The stored data does not only have backup & upgrade function, moreover it can also be seen as a portable BIOS chip which is actually able to boot up your PC. 760GM-P21 (FX) features Active Phase Switching (APS) technology, which is an intelligent design that helps to save energy on MSIs mainboards. The underlying idea is to switch off the power supply as soon as no electricity is needed, & when the system needs more resources again, APS will automatically adjust electricity supply accordingly. APS will automatically detect your processors loading at any given time & save energy accordingly.
