I am going to buy an asus prime b360m-k with i5 9400f, will they work together out of the box or it will need a bios update??
Like he said it's a cointoss, I bought a clearance EVGA B360 to pair with a 9400f that just happened to support 9th gen out of the box as it was likely a later production model with updated BIOSThe asus prime b360m-k was made for the 8th gen cpu so most likely it will need a bios update before working with the 9400f. Depending what stock is on the shelf when you buy it asus might have installed an newer bios that would work with the 9th gen cpus but your really flipping a coin on that one.
You would need a b365 board for it to work straight out of the box.
