I think Asrock just saw the market gap and decided to put something out there.
Not the most interesting product, but it's giving a half decent mATX option to people who want a smaller AM3+ system. Much better than the Asus 760G board.
Given that the 8xxx series of cpus in the fx line are crazy power hogs.. im pretty sure that board wont live long. See I think AMD provided a minimum power phase design for certfication but by no means is it recommended.. I would suggest something with 6+ or better yet 8 or 8+2 .. they are generally nicer and the VRMs run much cooler thanks to the distribution of power
Maybe, the FX cpus have been out a long time and board manufactures should know what they are doing with the power delivery. Making a board with a high RMA rate isn't going to be very profitable.
