I have a MSI z270 gaming M7 motherboard. It requires a 8 pin and a 4 pin connection to power the CPU. But my PSU only has two 4 + 4 cables. I am unsure what to do. Should I use to 4-pin cables in the 8-pin connection? Or I got a raidmax 8 Pin M - F connector..... so, should I connect the 4 pin into the female part of the connector and connect the 8-pin male part into the CPU? Any help would be appreciated.

The aux connections (EPS) are not just to power the cpu, they are additional power to the cpu. The cpu gets most of its power from the 20+4 main connection. What the 8/4 are mostly for is higher OC demands. I'd just use the 4+4 in the 8pin slot. I'd be very careful of using any sort of adapters, the pinouts are not all the same, so just adding stuff will most likely have the wrong wires in the wrong pin slots, which almost guarantees that you will short out the mobo. So just use the EPS connector 4+4.

4+4=8pin EPS. They should lock together via a small clip inside the latches.

Although you have a CPU-Z validation link, it doesn't list your PSU's make an model. Can you please state it?

On another note, per your manual (page 25), you should connect your PSU's 4+4 pin EPS cable to the CPU_PWR1 ports and leave the CPU_PWR2 port with only a 4pin. The second 4+4 pin should only have one end that should plug into the CPU_PWR2 port. FYI, the CPU_PWR2 connection is only necessary if you're going to be overclocking to a high degree.

Also, another kinda related thing since we're talking about overclocking, is that my motherboard has OC Genie 2 and I wanted you that to OC my CPU but I don't know if I should send in the Bios OC to my Ram from 2133 megahertz to 3000 megahertz. Should I try to overclock or should I not even overclock the 7700k at all?

Before OC, READ. Everything. Google OC on your mobo, spend a lot of time on the Asus ROG forums, especially the OC sections, familiarize yourself with every bios setting that you don't fully understand. Learn exactly what OC is, how it pertains to your cpu / mobo / bios, just what you can expect from OC, whether it be high temps, high vcore voltages, what the multiplier does what other than vcore you need to look at etc. The more information you can gather on OC on your cpu/mobo the better.

Strongly advise learning everything you can before even considering pushing that button. Kinda akin to learning about gun safety before loading your rifle.
