https://videocardz.com/newz/asrock-working-on-four-b450-motherboards The B450 succeeds the mid-range B350 chipset, comes with out of the box support for Ryzen 2000 "Pinnacle Ridge" processors, and has a couple of features up its sleeve.
There are at least four B450 motherboards currently in development at ASRock headquarters (there might be 2 more):
- B450 Fatal1ty Gaming K4
- B450 Fatal1ty Gaming-ITX/ac
- B450M Pro4
- B450 Pro4
The new B450 comes with a reduced idle power-draw of less than 2W, and hence can be cooled by extremely tiny heatsinks. I personally find anything that can reduce heat in your PC a welcome addition.
