GTX 1080 ti has two 8 pin connector - what do I do

deadpacman · Aug 11, 2017

I have a semi modular psu. There's two red cables running out of it that are for gpu power. One is a 6+2pin but the other is only 6 pin. However, there's a non modular 8 pin connector coming from the psu as well, can I use that? (Along with the 6+2).

androbourne · Aug 11, 2017

Generally speaking. Yes you can use both.

I would look up your PSU manual and verify that 8 pin non modular cable before doing so to see what the manual states it is for.

However, the fact it is 8 pin. I doubt it will be a problem if it fits.

Ok thanks I'm asking because it's an older psu but an enthusiast friend said it's be fine. I was just confused because the red connectors look like they're for a gpu but the other 8 pin looks like a cpu connector (My mobo has an 8 pin cpu slot)

androbourne · Aug 11, 2017

I would suspect it is fine also. That is why there are pins of different types (2 pin, 4 pin, 6 pin, 8 pin) etc... each providing different power limits.

But I still recommend you look up what it states it is for in the manual.

What psu is it, because that 8 pin plug is probably for the cpu seemed so you have a 6+2 and a 6 pin plug. It shoulden't fit unless unless you force it but safe to check first

It's a 600w ocz modx stream pro

You're right it doesn't fit. God damnit

deadpacman :

No! the "Non-modular" 8 pin coming from the PSU is EPS, for the CPU. This is not made to power PCIe cards. Purchase a 6pin to 8pin adapter. Link to what I am talking about below. Also, what do you have plugged into the CPU power connector on the motherboard if you have that one available?

Thats a cpu plug. I have one of those too and its only 6+2 and 6 pin plug for gpu. Sorry mate that isn't going to work

androbourne · Aug 11, 2017

Yes if it doesn't fit then it wont work.

But this is also why I said look it up in the manual. A lot of CPU's provide the correct power pins for a PCI device as well.

androbourne :

you just edited that in...

androbourne :

The EPS 8Pin is wired differently and won't even plug in to a PCIE PEG.

Edit: you can buy 6 to 8pin adapters. I would go that route.

matthew_nicho2 :

Read the original comment....

It was the first thing I said to do and it wasn't edited at all.

But nice try.

"I would look up your PSU manual and verify that 8 pin non modular cable before doing so to see what the manual states it is for."

But go head and down vote for telling the OP the correct thing to do.

matthew_nicho2 · Aug 11, 2017

"androbourne has edited this post 4 minutes ago" and posted a minute after that

androbourne · Aug 11, 2017

Yes for typos. It was in my original post before you even posted the first time. If you want to QQ further on it call mod to check it. I'm sure there is versioning enabled on the forums, they can look at to confirm.

matthew_nicho2 · Aug 11, 2017

Whatever, deadpacman's 1080ti isn't busted so i'm happy

androbourne · Aug 11, 2017

And thats great.

If he was to read the manual or even tried to put the pin in. He would have seen it wasn't compatible anyhow.

Hence my comment to read the manual. It goes without saying that is the reasonable thing to do first.

iamacow · Aug 11, 2017

You guys are funny. Ones trying to backtrack and the other won't give up.

androbourne · Aug 11, 2017

Not backtracking anything. I was the only one to recommend looking at the manual to start with.

The recommendation still stands and again, feel free to call a Mod in there to verify the original post for all I care.

matthew_nicho2 · Aug 11, 2017

I'm done. I'm not that petty. I didn't think he mentioned the manual. Maybe he did maybe he didn't All that matters is an expensive piece of equipment wasn't destroyed.

androbourne · Aug 11, 2017

Again, which wouldn't have been an issue because that pin type doesn't even fit into the GPU socket.

Many PSUs have cables needed to PCI slots. This is why I said use the manual.

Next time, read the reply before attempting to down someone on their troubleshooting methods. As referring to the manual was a correct response, which you didn't even mentioned.

madmatt30 · Aug 11, 2017

Replace the psu anyway .
If you can afford a $700 GPU you can afford a new $70 PSU to run it on.

The modstream was a mediocre PSU in its day & was produced in 2010.

Ocz don't even make psu's anymore.
