Board Layout
Once I had the Biostar Racing Z370GT6 out of its bag, I noticed two things right away. First, there is no rainbow "R" anywhere on this board. Second, it doesn't need one because it has a very classy black and gold theme.
There is a fair bit of space around the socket; fitting the cooler of your choice shouldn't be an issue. Alongside the socket are the four DDR4 DIMM slots, with the first of two M.2 slots just below it.
The second M.2 is underneath a stylish heatsink Biostar includes, a feature I and my often toasty Samsung 950 Pro SSD thoroughly appreciate.
The Biostar Racing Z370GT6 has three PCIe x16 slots, the top two being metal-reinforced, as well as three PCIe x1 ports. There are six standard SATA 6 Gb/s plugs on the board's right edge, and a veritable plethora of pin headers are situated along the bottom edge. Three fan headers and no less than four USB headers are joined by the usual front panel and audio headers and an S/PDIF out.
The rear I/O on the Biostar Racing Z370GT6 is pretty spartan with only six USB type-A ports and a type-C port. Ethernet, DVI, HDMI, PS/2, and audio jacks are also present. The Ethernet is powered by an Intel I-219V chip.
