Apart from the two Black Extreme models based on the Z77 chipset, ECS also has a value ATX motherboard that will capture a key sub-$150 price point, the Z77H2-A3. It is designed for single graphics cards, and lends the platform with all the connectivity and overclocking capabilities of the Z77 chipset. The CPU is powered by a simple 6-phase VRM, although the PCB is narrow (305 x 210 mm), there's room for four DDR3 DIMM slots. Expansion slots include one PCI-Express 3.0 x16, four PCIe x1, and two PCI.

The Z77H2-A3 doesn't add much features beyond what the chipset does. There are two SATA 6 Gb/s, four SATA 3 Gb/s, 8-channel HD audio, gigabit Ethernet, display connectivity that includes D-Sub, DVI/HDMI (variants), and four USB 3.0 ports (two on the rear-panel, two via headers). UEFI with graphical setup program and ECS EZ-Charger come standard.
