PSU modular is 10 pin PCIe the same as 8pin?

As the title says, I have a seasionic X560 modular psu that has 2 10pin pcie slots. I don't have pcie 10 to 8+8 cables, but I do have 2 pcie 8 to 6+2 cables.

My question is, can I put the 8 pin cables into the 10 pin slots? They are the right shape, but I have to cut the clip to get it all the way in.

I'm kinda stuck here, I don't want to fry my fury x (2x 8pin connector). Help is appreciated :)

There is no such thing as a 10-pin PCI-E external power connector. It simply doesn't exist. Your PSU has 1 4+4-pin CPU power connectors and 2 6+2-pin PCI-E power connectors. Also a 12+8-pin ATX motherboard power connector doesn't exist, you have a 20+4-pin one.

Read TL;DR if you want a quick answer.

You're talking about the headers on the PSU itself. Those are a completely different set of connectors that are proprietary to each PSU.

They do NOT conform to any of the regular connector standards. The PCI-E labeling is there to tell you which cables that came with the PSU slot in to that header. Therefore, any cable that you have marked PCI-E...


I have a x560, which has 12+8 pin for the motherboard, one 8 for the cpu and two 10pin PCIe connectors (it says so beneath), I would like to know if I can jam a 8pin into a 10pin slot and make it work without breaking my gpu
 
As far as I know, a 10 pin PCIe connector does not exist. There are 6 pin and 8pin (which is basically 6+2 pin). Please check before in your GPU and PSU. You have to use the connectors that have the exact number of pins and shape.

Well there are 10 pin ones that split up in 8+8 pcie, only on the high end psus. I've cut the notch that prevented me from inserting them, is looks like that works.

They do NOT conform to any of the regular connector standards. The PCI-E labeling is there to tell you which cables that came with the PSU slot in to that header. Therefore, any cable that you have marked PCI-E, whether it's an 8-pin or 6-pin cable (Which it won't be, since your PSU didn't come with these) or a 6+2-pin cable (Which it will be, since this is what your PSU came with.) will fit in that 10-pin slot. Remember, 8-pin and 6+2-pin PCI-E cables are interchangeable; the whole point of having a 6+2-pin cable is that you can use it either as a 6-pin or 8-pin PCI-E cable.

TL;DR: Yes you can use your "PCI-E 8 to 6+2" cables in that slot. If you want an explanation of why your line of thinking is flawed, please read the stuff above. :)

If you cut anything that prevents you from slotting a cable in, then it won't work. That notch is there for a reason; if you connect two sets of pins other than the ones intended, there will be excess power flowing where it's not supposed to go, or vice-versa. This WILL fry your GPU, so please don't do anything of this nature.
