Could I use an 8 pin extension with a 6 pin?

post #1 of 12
Thread Starter 
I have a spare 8 pin extension and was wondering if I could plug in a 6 pin into it so I could plug that into the 8 pin slot on my new video card. Would that work?

You could use a 6 pin extender on an 8-pin cord to plug into a 6 pin card. But since your card needs an 8 pin, it won't work.

No, those 2 extra pins could be important. Get a proper 8pin adapter if you lack the 8pin plug on your PSU.

I believe they're extra grounds. Or it was one ground, one power. I forget exactly.

wouldn't risk it mate.

They're both extra ground pins, the card should still work normally at stock speeds if you do this, but Catalyst will most likely grey out the 'Overdrive' section, stopping you from overclocking.

At least that's what happens to older cards, not sure how the new 7970's behave :/

EDIT: Ok, a quick google search seems to suggest those Delta 1000W's are a fairly high quality PSU, but then why does a good quality PSU not have at least two each of 8 & 6 pin PCI-E plugs....

Ok so would it be safe to do it? I really don't care about overclocking honestly, I just want it to run normally.

So just to reiterate. This will work perfectly fine when hooking it up to a 6 pin power connector and installing it into the 8 pin power connector?511

That looks like a 12v cable and not a video card one
