I'm trying to figure out how to connect a

• Seasonic 650W SS-650KM Active PFC F3 Power Supply Unit

to a

• AsRock X470 Taichi motherboard

I connected the (16 + 10)-pin "M/B" cable to the motherboard main power socket.

On the top PSU offers additonal cables that I cannot find what to do with:

• one (8 + 4)-pin "PSU" cable
• two (6 + 2)-pin "PCI-E / CPU 8P" cables

On the top of the motherboard are two sockets:

• one 8-pin "ATX12V1" (ATX 12V #1)
• one 4-pin "ATX12V2" (ATX 12V #2)

On the motherboard, I cannot see socket to power the CPU, nor the PCI-Express slots.

Here are my questions:

• Is the PSU not adapted to the motherboard?
• Do I have to power the ATX sockets on the motherboard, and how?
• Do I simply have to left the PSU's CPU and PCI-E cables unused?

Thanks a lot.
