I am currently building my first PC and although everything so far has gone fine, I have found myself suddenly stuck trying to figure out how to cable my hardware properly to my PSU. If anyone can also advise on what power cables I need for the other hardware as well that would be a great help!

My hardware:

- Asus X99-A II Socket LGA 2011-v3 8-Channel HD Audio ATX Motherboard
- Corsair RM750i RMi Series 750 Watt Fully Modular Power Supply Unit 80 Plus Gold Certified
- Asus GeForce GTX 1070 8GB GDDR5 DVI-D HDMI DisplayPort PCI-E Graphics Card
- Intel Core i7-6800K 3.4GHz Socket LGA2011-3 15M Cache Retail Boxed Processor
- Samsung 750 EVO 500GB SATAIII 2.5inch SSD
- HyperX Fury Black 16GB (8GB x2 Kit) DDR4-2133MHz Cl 14 DIMM Memory

Thanks!

You would plug both your GPU power cables and the cables for your GPU into the section labeled 6+2 PCI-E and 4+4 CPU. The 6+2 cables combine for an 8pin for your GPU. the 4+4 Pin combine for the 8pin power cable for your motherboard. The extra 4pin for motherboard(extra OC power) is optional. I'm not sure if your PSU has an additional cable for this, though I'm using a similar motherboard, OC'd as well, and using just the 8pin. There are 8 pin extensions to reach your motherboard 8pin like you mention. The 4 pin is again optional, it depends on what cables your PSU came with. All your SSD/HDD, ect. would plug into the SATA and Peripheral connections on your PSU.

The PSU and motherboard should provide you with all the cables you need. There will be a 24pin main connector along with an 8pin EPS power cable that connect to your motherboard. There will also be 1 or 2 8pin PCI-E cables that connect to your 1070. These 8 pin cables are keyed differently that the motherboard version, so they don't get mixed up. Your SSD will need a smaller 15pin SATA power cable from the PSU along with the 7pin data cable to connect the SSD to the motherboard. Your fans will most likely connect with fan headers on your motherboard. The connections on your PSU and motherboard should be clearly labeled. If you need more specifics, the manual included with them will show you in greater detail.

Ok. My Graphics Card has a single 8 pin socket and my power supply has this:

So what do I plug into the PSU and where if I use an 8 pin one end for the graphics card?

Apparently my manual for my motherboard says I need to plug both an 8 pin cable from it to the PSU as well as a 4 pin (for overclocking I think). What cables do I need for this?
ATM I have used an 8 pin to 8pin cable for the 8 pin connector for the motherboard to the top right most connector on the PSU. Is this correct? How do I plug in the 4 pin to the PSU?
