Help connecting GPU to PSU

I have a Corsair CX600M Power Supply and I've been trying for weeks to connect it to my Asus Radeon R7 370 Graphics Card. I'm a new builder and I cant seem to figure out how to connect the 8 pin to 6+2 pin PCI-E connector. I've tried researching forums but nothing makes sense. I figured that I plug the 6+2 pin side of the cord into my PSU and try to plug the 8 pin side into the GPU, but the 8 pin doesn't fit into my GPU. I don't have the pigtail cable that the PSU should come with. I read that that could be a possible solution, would I need to buy that? Would I need to buy a 6+2 to 6 pin cable? Any help is very appreciated, Thanks.

I assume I wouldn't put the 8 pin in the 4x4 CPU port correct? The 8 pin doesn't fit in the 6+2 pin (but really just 6) slot

How the CPU port get involved here? It has nothing to do with this. What is a "6+2 but really just 6?" The connectors are standardized -- every 6+2 PCIe end will go into a GPU that requires it. But then you say you don't have the cable at all (which you quite obviously need). Do you have the cable or don't you? The Corsair CX600M comes with these cables:

• ATX Connector x 1
• EPS Connector x 1 (2x 4-pin)
• PCI-E Connector x 2 (2x 6+2-pin)
• 4 Pin Peripheral Connector 1 x 4
• SATA Connector 2 x 3
• Floppy Connector x 1

So what do you and don't you have?

I have a 6+2 to 8 pin cord. The PSU usually comes with the pigtail cord so 2x 6+2s, I have just one, which isn't a big deal I only one. What I meant by 6+2 but really just 6 was that on the PSU the PCI-E slot has a 6+2 connection but it's only actually 6 slots so my 8 pin will not fit into it.

Personally, I think you need to pay for in-person help at a shop so that someone can actually *look* at what's going on, because your explanations are impossible for me to parse. Or perhaps someone else here will be able to figure out what you're talking about. I wish you the best of luck resolving your issues!
 
I read that the PSU has two 6+2 pin connectors. Your 370 requires one 6+2 pin connector, correct? This means, since your PSU is modular, you only need ONE pci-ex cable to be used.

Here's where I think you're lost. The end with the 6+2 connector goes to the videocard. If the card only requires a 6 pin, then you simply leave the extra 2 pin connector loose. The other end of that cable plugs into the power supply.

I knew that that was what I needed, I need help plugging in the other end, the other end is a 8 pin plug while the plug-in says 6+2 but it only has 6 connectors so the connectors don't match, it will fit, but I have 2 extra pins that I can't disconnect. Can I make the 8 pin into a 6+2 by cutting it or something?

 


Your power supply is modular, you need to plug in that PCIe power cable into the power supply, only one end of the cable will fit. Then the 6+2 connector will go to the video card. Not really sure where you are getting confused unless you have cables that did not come with that power supply for some reason. You should have two 6+2 PCIe power plugs and another 6+2 CPU power plug. The ends that do come come into two parts go into the power supply, the ends that split into two go into the components.
