Gigabyte released its newest premium HTPC motherboard in the mini-ITX form-factor, the A75N-USB3. As the name might suggest, this is a socket FM1 motherboard based on the AMD A75 chipset, and features USB 3.0 connectivity. Despite its compact dimensions, the board crams in everything a HTPC can benefit from. First, the FM1 socket seats AMD A-Series accelerated processing units (APUs), which pack up to four x86-64 cores with up to 4 MB cache, dual-channel DDR3-1866 integrated memory controller, and more importantly, a very powerful integrated graphics processor in the Radeon HD 6500 class. The FM1 socket on this board is powered by a 3+1 phase VRM that makes use of driver-MOSFETs. Power is drawn by a 24-pin ATX and a 4-pin CPU power connector.

The lone expansion slot is a PCI-Express 2.0 x16. The CPU is wired to two full-length DDR3 DIMM slots, which can take in up to 32 GB (that's right, future 16 GB DIMMs are supported) of dual-channel DDR3-1866 MHz memory. The AMD A75 chipset gives out four internal SATA 6 Gb/s ports, and one eSATA 6 Gb/s port on the rear panel. Display outputs include HDMI 1.4a and DVI. Analog outputs are done away with. Audio is handled by a high-quality Realtek ALC889 HD audio codec. Although this codec supports 8+2 output channels, it is wired to a 5.1 channel shared audio jack cluster, apart from the internal HDA_FP header. Those needing 7.1 channel output can still use the TOSLINK connector, that supports 7.1 channel output with 24-bit, 192 kHz resolution and Dolby Home Theater support. If even that's not enough, the HDMI connector gives you 7.1 channel HDMI audio with Dolby Prologic support.The lone gigabit Ethernet connection is handled by a Realtek RTL8111E PCIe chip, there are just two USB 2.0 ports apart from two more via internal header, but there are as many as four USB 3.0 ports on the rear panel, driven by the AMD A75 chipset's integrated USB 3.0 controller. Despite severe space constraints, Gigabyte made room for two sets of BIOS EEPROM chips, to give you DualBIOS (your insurance against failed BIOS updates). The board uses traditional AwardBIOS, but features HybridEFI, which lets you boot from volumes greater than 2.2 TB in size. There is no word on the pricing of this board.
