4pinx2 on psu vs. 8pin on motherboard

[MsNN]

I have a Coolermaster Silent Pro 700 PSU and AsRock z68 extreme 4 board.
PSU has a 'CPU 4 4 pin' connector, which consists of two

and

Their wires are the same black and yellow, as I understand double 12v and double ground. The same time, 8pin atx power connector on motherboard looks a bit different

Can I use mentioned 4 4 from PSU to connect it to motherboards 8pin?

Should be able to, yes.

Just don't plug in a 6+2 pin video card plug into a motherboard 8 pin...

The 4+4 pin ones are safe to plug in the mobo.

Silvune,jasonw223 thanks, I'll try to use 4+4.

The reason its split into two 4pin blocks is for older Mobo's that only have a 4pin socket,

Moto is correct, the 4+4 allows the PSU to work with boards that need an 8 pin as well as those that can only take a 4 pin connector. As to why the +4 connected has 4 rounded pins im not sure but they are all like that and you can use either half in a 4 pin motherboard as the wiring is identical for both sides.
