6+2 pin power supply plug connects to 8 pin motherboard

[ccmelyx]

Hi guys I'm very new to PC diy and I recently bought a MSI Z97S SLI Plus LGA 1150 motherboard and a Rosewill CAPSTONE-750 PSU. The motherboard has a 8 pin JPWR2 slot, but the PSU only has 6+2 PCI Express plugs. While the "6" can fit into the JPWR2 slot, the "2" cannot fit at all.

So what am I supposed to do? Much appreciated for any advice.

Don't use that for the CPU power header. The PSU has a 4+4 connector that fits together to make an 8 pin connector for that header.

Yes I have found it with U1 and CP written on the connectors. Thanks a lot!
