Board Layout
Other than the obvious checkered flag across the front of the Biostar Gaming Z270GT4, the way this board looks is muted for sure. There is black all over, with a touch of white here and there. The rear of the board is fairly basic, but Biostar has not neglected to include some solder strips there to help with CPU VRM cooling.
The socket area is nice and open, with no MOSFET cooler above the CPU socket area. There are four DIMM slots next to the socket, rated for speeds up to 3200 MHz. This is a fair bit lower than on some other boards, but when you consider that the default speed for this platform is 2400 MHz, a 33% increase in support is more than ample for most budget-conscious users.
There are two PCIe x16 slots here on the Biostar Racing Z270GT4, with two PCIe x1 slots sandwiched between them. The back panel has every video connector you could want for a PC monitor, along with a splash of USB and audio in various flavors, although I was quick to notice the lack of a dedicated digital audio plug, but such can be had over HDMI for sure. A PS/2 port and LAN plug round out the functionality here.
There is a single M.2 port, placed above the PCIe slots. It does support NVME devices such as the Samsung 950 PRO I use in my testing rig. SATA connectivity features six ports total. I was really surprised to see a U.2 port here too!
The bottom edge of the board is pretty basic, although you might notice there are two socketed BIOS chips here. You couldn't really ask for more.
LAN connectivity on the Biostar Racing Z270GT4 is provided by an Intel controller, while close by the socket is a "LAN Protect" chip to help prevent surges over the LAN port.
An NXP TMDS chip manages the HDMI.
