What cables do I need?

Specs: Windows 10, gtx 1070
Hey guys! So i plan on purchasing a gtx 1070 for an upgrade and im a bit stumped on what cable/cables i will need. I have a semi modular 550 watt rosewill power supply with 1 pcie 8 pin slot on it, im upgrading from a 750 so no power was needed to the gpu. do i use a 8 pin female to female power connector or something else? Thanks!

can you tell me what kind of gtx 1070 you are planning to buy & chat brand/ what model of PSU you have (smi 550)?

im pretty sure this is the PSU https://www.newegg.com/Product/Prod... and getting the 1070 founder edition. I did more research and supposedly my psu comes with an 8 pin pcie connector but I dont have it anymore so im not sure what to get.

its fine, you got 3 8-pins(1 for the CPU 2 for the GPU, but 1 8-pin can handle 300watt for an overclocked GTX 1070), a 24-pin for the motherboard.
i do reccomend getting an aftermarket gtx 1070, the founders cards have really bad cooling & will perform about 10% worse.

so if you can get one of those strix or msi gaming x cards for roughly the same price please do.

The 8-pin PCIe connector & 8-pin CPU connector are completely different things. Don't mix them up. Also, the 8-pin PCIe can handle up to 150W, not 300W. The PCIe slot itself can handle up to 75W. NVIDIA rates the GTX 1070 at 150W.

All you need is the 8pin PCIe connector and that is/was supplied with the power supply.

Edit: riider: Hidde has always been a 'bit' loose with the numbers, especially on overclocking.

I think the OP's problem is that he has lost the cable that came with his PSU.

Be careful - use the wrong cable and it could fry your new graphics card as not all modular PSUs use the same cables (even if they look identical). I would recommend that you contact Rosewill for a replacement: http://www.rosewill.com/spare-part-...

pic is me running 340+ watt using a single 8-pin for a few seconds

yes my rx 570 is rated for 120~180 watt. Doesn't mean i cant run 300+ watt through it :)
yes my VRM will explode it i keep that up
yes my GPU core will degrade over time running 1.3volt instead of 1.05

Hey thanks a lot guys i put in a request through rosewill for a 8 pin connector. But for future reference something like this will not work or just not recommended? https://www.newegg.com/Product/Prod...

Not recommended because they do not specify which power supplies it fits and they will not pay to replace your graphics card if it causes an issue. Much better to get the original part or at least one specifically made for it.

"i put in a request through rosewill for a 8 pin connector"

Hold on there! The PSU you posted a link to in response #2 is NOT modular, so that cable will be useless. According to the specs, it has "2 x 6+2-Pin PCI-E Connector", so you shouldn't need a thing. You already have two 8-pin PCIe plugs.

Here's a pic from newegg clearly showing the PCIE plugs: https://c1.neweggimages.com/NeweggI...

You might need to snap the 2-pin plug onto the side of the 6-pin plug to create an 8-pin plug. The connector is designed that way because some PCIe cards only require a 6-pin plug. http://i.imgur.com/0XXJuyA.jpg

The cable from NewEgg is most definitely wrong. It's an extension cable, not a replacement cable to plug directly into the PSU, and there is no guarantee that the pinouts are correct.
