Socket LGA 1155 H77 platform

The GIGABYTE GA-H77M-D3H is a Micro ATX board built around the Intel H77 chipset for LGA 1155 processors. It accepts Core i7, i5, i3, Pentium and Celeron CPUs and supports up to 32 GB of DDR3 memory across four 240-pin slots running at 1600, 1333 or 1066 MHz. Integrated graphics output is available when the installed CPU provides it.

Expansion layout and rear I/O

One PCI Express 3.0 x16 slot and one PCI Express 2.0 x16 slot wired at x4 sit alongside a single PCI Express x1 slot and a legacy PCI slot for older add-in cards. Storage connects through two SATA 6 Gb/s ports and four SATA 3 Gb/s ports with RAID 0, 1, 5 and 10 support. The back panel supplies HDMI, a PS/2 combo port, two USB 3.0 ports and four USB 2.0/1.1 ports. Gigabit LAN tops out at 1 Gbps.

Thermals and power characteristics

The H77 chipset and voltage regulation run cool enough for standard Micro ATX chassis airflow without specialised cooling. Onboard audio uses the VIA VT2021 codec for eight-channel output. With no high-wattage components onboard, the board draws modest power in typical desktop workloads and adds negligible acoustic load to the system.

Questions about this item

Will this board take my LGA 1155 Core i5 and DDR3 1600 memory?

Yes, the LGA 1155 socket supports Core i7, i5, i3, Pentium and Celeron CPUs, and the four 240-pin slots run DDR3 at 1600, 1333 or 1066 in dual-channel mode up to 32 GB total.

Can I add a modern graphics card and two SATA SSDs?

The board provides one PCI Express 3.0 x16 slot for a graphics card and two SATA 6 Gb/s ports plus four SATA 3 Gb/s ports for drives; RAID 0, 1, 5 and 10 are supported on the SATA ports.

What video output does the back panel give if my CPU has integrated graphics?

The rear I/O includes one HDMI port that is driven by the CPU’s integrated graphics; if the processor lacks graphics you will need a discrete card.
