Can I power this gpu with the cables I have?

[noktek]

Hello folks I am trying to add back an old gpu to my also old system but I don't understand how to do it. It seems I have no way to do it as a cable might be missing! The gtx780 uses 6+8 pins and the gtc275 needs another 6+6 but I don't seem to have any free ones? How can I do? I only have the cables I am holding in the picture

Dont see a picture maybe it is just me, what PSU do you have, and why are you trying to add a 275 it would probably hurt performance if you were going to offload Physx to it.

For rendering purposes! I know it's an old piece of crap but at least I can keep working while the 780 is fully under load! https://ibb.co/jO76vb here's the picture idk why it's not showing up

The picture shows you have Corsair HX850. According to this review http://www.hardwaresecrets.com/corsair-hx850w-power-supply-review/
it comes with

Four auxiliary power cables for video cards, with one six/eight-pin connector on each one of them.

That should be enough for your needs - unless you lost some of the cables though.

So i would ignore the 6 pin to 8 pin converter, you are holding as you mentioned 2x 6+2 pins. The HX850 came with more PCI-Express cables totaling 6 (you have 2 in the picture) You will need to find the other cables.

There should be additional modular cables, you can connect to your PSU.
This is Corsair HX850W modular cable set.

Malwarebytes aswell as few other anti-viruses and anti-malware programs are blocking ibb.co as they were allowing uploads images with malware attached to them.

There seems to be two versions of HX850 though.

That one has 4 PCIe cables EDIT: two more non-modular though, so also 6

That one has 6 cables

Hi guys and thanks for all the answers you're way too kind! I went in the attic and in the cellar and I can't find the leftover box anymore so I guess it's been lost since I've moved a couple if times in the past years.. All the pictures look like what I had... So fundamentally I just need a couple of these cables with 6+2 pins on their extremities and just plug them into the psu? Guess I'll go hunt those cables tomorrow then

Yes, that what you can do. But make sure the cables are compatible with your PSU model - not all cables are. Sure, the plugs on GPU side will be identical on all of them, but those on the other end not necessarily.
