Component Analysis

The single chipset for B850 allows for more space on the south of the PCB and a larger M.2 heatsink as a result. The chipset also has a much larger heatsink than on some competing boards, but Gigabyte has done a good job of combining the two seamlessly to not spoil the aesthetics.


If you're not keen on Realtek's USB-based ALC4080 codec then you'll be pleased to see that ALC1220 is used here. Realtek also provides the network controller in the form of the 2.5 Gbps RTL8125D.


Internally the Wi-Fi 7 module uses standard micro connectors, while these convert outwards to Gigabyte's Wi-Fi EZ Plug. The module is relatively easy to remove if you need to, but as both VRM heatsinks are linked, you'll need to remove both before also detaching the I/O shield and a small plastic shroud over the top of it.
