Biostar TA870+: The Weakest of the Strong @ InsideHW
Quote: "Biostarís TA870+ motherboard uses the SB850 southbridge in conjunction with this chip, therefore integrating native 6 Gbps support, but (as we know from previous tests) has no USB 3.0 ports. Biostar decided not to include them via a separate controller, which helped retain the price on an acceptably low level. The 870 chip itself contains no graphics core, and its consumption should be around 13W."
