It looks like that 8-pin connector can be split. Can't really figure out the mechanism from the picture, but that little rise/edge is likely what is holding the 2 parts together. Split that one up, plug that into the CPU 4-pin power socket and she should start up just fine.

* oh, also; move that 2nd RAM module to slot #3. That let's the RAM run in dual-channel mode. Just use the slots with matching colors (1&3, 2&4)
You may need to go into BIOS and configure the timings and speed for the RAM manually as well, not all of those come with the proper settings on the SPD.

** had a look, board supports CPU just fine. No worries there.

You were right about the RAM, thanks. We found that the 8plug works by just plugging it into the 4 plug, with 1/2 hanging over the side
