Firmware

To give you a taste of the Firmware, we’ve gathered screenshots showing a majority of the BIOS screens. There’s not much here we haven’t seen before. The theme is different compared to the ROG boards. You get  a black, white and blue color scheme, but outside of that, it is still a typical Asus BIOS. Most functions are not buried deep within the menus, and it’s generally easy to navigate and find what you’re looking for.

    This board has VRM with 4+2 phases and only 3 capacitors in the 12V filter. I think a 95-105W CPU with PBO can rip(ple) them fast.

    ...and has the cheast sound you can get. Its only a couple bucks more to at least upgrade to 1200 sound (not even the newer 12xx ones). Sounds like a board designed only to run 65W chips, especially if you want to OC One. if you arnt going to OC just get the new 520 boards that are cheaper.
