LGA 1155 desktop board

The GIGABYTE GA-H77-DS3H is an ATX motherboard built around the Intel H77 chipset for LGA 1155 processors. It accepts Core i7, i5, i3, Pentium and Celeron CPUs and provides four 240-pin slots for DDR3 memory up to 32 GB in dual-channel mode.

Thermals noise and power

The board uses standard voltage-regulation and fan-header layouts typical of the H77 platform, so thermal performance and acoustic output depend on the chosen CPU cooler and case airflow. Power draw scales with the installed processor and the number of active expansion cards.

Expansion and I/O

One PCI Express 3.0 x16 slot and one PCI Express 2.0 x16 slot running at x4 give room for a graphics card and an additional add-in board. Two PCI Express x1 slots and two legacy PCI slots support older peripherals. Storage includes two SATA 6 Gb/s ports and three SATA 3 Gb/s ports with RAID 0, 1, 5 and 10. Rear I/O supplies HDMI, a PS/2 combo port, two USB 3.0 ports and four USB 2.0/1.1 ports. Gigabit LAN and 8-channel Realtek ALC887 audio complete the connectivity.
