Gigabyte Thin Mini-ITX motherboards

GIGABYTE Thin-Mini-ITX motherboards are the ideal platform for today’s All-in-One(AIO) slim and small PCs. Gigabyte recently launched two thin Mini-ITX motherboards. One is GA-H77TN and the other is GA-B75TN. Let’s take a look one by one, starting with H77TN.

Gigabyte GA-H77TN


This mini motherboard is latest, powerful and thin and is 2.5 cm tall. It supports Intel Core i7, i5 and i3 processors and lesser. With a chipset of Intel H77 Express, it has two 1.5V DDR3 supporting up to 8 GB of system memory on 2 SO-DIMM slots instead of the regular DIMMs. It also has an HDMI 1.3 port, LVDS port and Display port on the opposite side of the board, with superior screen resolutions (2000×1600 +). Realtek ALC887 high definition sound card for the audio and Realtek GbE LAN chip for the lan card.

Now, instead of the regular 24-pin ATX power connection, it has the external power inputs. It has a selectable power requirements – 19 volts and 12 volts, a jumper does the selecting of either of these. With 4 PCI expansive slots you can slot any cards like TV Tuners and more and will always have a room for an extra slot depending on your usage. It has an onboard mSATA and a Mini PCIe to slot in your SSDs and a 3.5 inch hard drive slot, the power to this comes directly and not from the mother board.

2 SATA 6 Gb/s and 2 more SATA 3 Gb/s gives a good connectivity to storage and is more than enough for this thin mini series.

The cooling fan sits in the middle of the chassis and does all the job of cooling warm air so no fan over CPU, as this would be against their thin form factor goal.

The whole package, with all the internal I/O connectors is the usual 17.0cm x 17.0cm in size but you can see it’s thinner, in fact 43% thinner than the usual 4.4 cm tall Mini-ITX motherboards.


Now. lets take a look at GA-B75TN model and as well as see what’s the difference between the two.

Just the chipset, the former model uses a Intel® H77 Express Chipset while this one uses Intel® B75 Express Chipset
