newbie installing GTX 1070 pin connector question

[geetargeek]

Hello,

Please pardon my lack of knowledge about this stuff in advance. I am attempting to put in a new video card and I have no prior computer build experience. I just purchased a Evga 1070 FTW and am replacing my current video card (Amd R9280) with it. I successfully removed the old card and got the new card into place. My confusion stems from the pin connectors. The old R280 used a 6(+2) and 6 connection, while the 1070 requires a 8+8 pin connection.

Evga included these weird dual 6 pin to 8 pin connectors. So far, I reconnected the original 6(+2) pin into the 1070, but was left with only the 6 pin connector from before. Can I connect the other 6 pin connector into the dual 6 pin to 8 pin connector and connect that to the 1070 (whilst leaving one of the 6 pin connectors unplugged? Or do I have to go out and buy a 6 pin to 8 pin conversion? Please see my pictures to better understand what I mean. Really appreciate your responses guys. I am afraid to go any further without knowing what I'm doing.

So, for the remaining 8-pin adapter that came with the GPU, you need to use TWO 6-pin PCIe connectors from the PSU.

If you don't have two 6-pin PCIe connectors from the PSU available, you honestly should buy a new PSU since your current PSU might not be good enough to power the GTX 1070.

Exactly what is the make and model of your current PSU?

Don't use the EVGA adapters use your PSU PCIE CABLES. You have plenty of power to run a 1070.

XFX 650W is more than enough power.

USE 2 - 6+2 connections , just leave out the +2 on the 6 pin card connection.

Please forgive my lack of computer knowledge. Blackbird, are you saying I can use the original 8 + 6 pin setup on the 1070 afterall? I'm on an Asrock Z97 Pro 3, if that helps.

 

[Dark Lord of Tech]

Yes you don't need the adapters from EVGA

USE 2 - 6+2 connections , just leave out the +2 on the 6 pin card connection.

Your power supply should have four PCI-E power connectors, each with a 6+2 pin plug.
Connect to of these to your graphics card, connecting the full 8 pins.

The adapter they give you is only for power supplies that don't have enough 8-pin connectors.
When using these adapters, you need 2 x 6-pin connectors from your power supply rather than 1 x 8-pin.

Depending on the 650W XFX MODEL

It should have:

2 x 6-Pin, 2 x 6+2-Pin ....Then you can also USE 1 - 6+2 and 1 - 6 Pin

His new card has 2 x 8-pin connectors. It was the old card with 8-pin + 6-pin.

If you're saying I can use 6(+2) for the first slot and 6 pin for the second slot, I will just do that. I was just under the impression that the 1070 required both slots to have 8 pins. Will that underpower the GPU? The previous card was a 6(+2) and 6 setup.

I looked at the power supply and tried to follow the cables. They go to a solid state drive, a hard drive, and so on. I don't see another 6(+2) pin connector free.

My bad misread the post 🙁, even easier just use the 2 - 6+2 PCIE connetions.

The problem is I don't see a second 6+2 PCIE connector? The setup I have is only 6(+2) and 6, not 6(+2) and 6(+2).

From the photo, it looks like you have fixed cabling on the PSU routed behind the tray. Take the other side of the case off and you will likely have a bunch of connectors tucked away.

You are awesome VincentP! I think I found it? Did what you said and took off the other cover and found this!

Just not sure how to thread it through to the front.

edit: looks like you found your solution

you should also seriously think about cleaning the dust out of your case, including the CPU cooler and fans. buy a can of compressed air, or use a low power leaf blower outside

And lastly, hopefully I didn't royally screw up by not uninstalling the AMD video drivers before putting this Nvideo card into the computer. I'm hoping I can uninstall them as soon as I boot the computer up before install the Nvidia drivers. Fingers crossed.

Cut the cable tie and pull out that cable. Use a cable tie to tidy up the other cable, or just a twist tie from some freezer bags in the kitchen if that's what you have.
You can thread the cable through the same hole in the tray as the existing PCI-E power cables.

download and run latest version of DDU to get rid of AMD drivers http://www.guru3d.com/files-details/display-driver-uninstaller-download.html

I would download the latest nvidia driver from www.geforce.com/drivers ahead of time so you're ready to reinstall right away

cheers

If you have problems, google "ddu" for a utility to clean old drivers up.
