Hello guys,
I was looking B450 Pro4 motherboard to buy but I have a question.
How the NVMe drive design on the motherboard.
Is there any news of M.2 is connected directly to the cpu or chipset?

Regards,

Greetings, this is ASRock TSD.

B450 Pro4 supports two M.2 sockets.
One (M2_1) is from the CPU signal, and the other (M2_2) is from the chipset signal.

1 x Ultra M.2 Socket (M2_1), supports M Key type 2242/2260/2280 M.2 PCI Express module up to Gen3 x4 (32 Gb/s) (with Summit Ridge, Raven Ridge and Pinnacle Ridge) or Gen3 x2 (16 Gb/s) (with Athlon 2xxGE series APU)
