The first of the three (technically, we’re going in alphabetical order here) is the Gigabyte Z77X-UD4H. The UD4H features a simple color scheme, with a black PCB and black and silver components accented with dark blue. There are sizable heatsinks on the Southbridge and the left side of the CPU socket, but the one north of the CPU looks somewhat sawed-off.
This mainboard features Gigabyte’s 3D Power engine and the associated all-digital PWM controller array. There’s a big red power button on the PCB itself, along with less conspicuous reset and CMOS switches. You can physically toggle between two BIOSes with the BIOS switch, and there are physical voltage measurement points on board and a debug LED display, too.
The UD4H supports essentially any Intel socket 1155 chip, as well as up to 32B of DDR3-2800(OC) memory.
