8-pin PCIE adapters

[CP5670]

Does anyone know where to get these cables for a reasonable price? I can only find them at Performance PCs, and they're kind of expensive at $10+7 shipping.

I got an XFX GTX 280 (from that 35% Live deal) but it doesn't include this adapter for some reason. I chose XFX for their transferable warranty and bundled game, but I'm wondering if I should have gotten some other brand now, as most of the other 280s come with the adapter. At the time I didn't realize that these adapters were so hard to find for individual sale.

My power supply lacks the 8-pin plug but is sufficient otherwise, and I would prefer not to buy a new one unless it was absolutely necessary.

What psu do you gots

It's an OCZ 520 Powerstream. I have measured my current setup's power usage to be around 235W on load, and from the reviews I've seen, the new card uses 60-80W more than my existing X1900XTX, so it should work fine if I can get an adapter.

The bfgstore had them for $5 plus shipping last time I looked. It was a single 6 to 8 pin adapter though not the 2x6 to 8 pin adapters included with the cards. They may have those for sale now though too as it was a month ago when I last looked.

I'll talk to JonnyGURU next time I see him if we can put some 2x6=8 adaptors for sale on BFGstore.

I found the the single 6-pin kind on there and the price is good, but they're out of stock. Do you know how long they typically take to get more?

I would prefer the dual 6-pin variety, but I can't find those for sale anywhere at all even though they're very commonly bundled with the cards. If anyone here got this adapter with their card and doesn't need it, PM me if you're willing to sell it for a few dollars.

Glad you were able to get in on the deal.

I shoulda got the XFX I guess lol, its got some nice add-ins and I didn't need the 8-pin adapter. I'm not sure you want to use it though as it says right on it that it can be unstable and isn't recommend for use long-term.

If you have a MicroCenter or similar near you, I'm pretty sure you can buy one or even make one with 6 and 8-pin connectors. Otherwise I can send you mine for cost of shipping I guess, even though I like to keep all accessories for potential resale. Anyways LMK.

This is what you need, but it's not exactly cheap for something that should come with the card IMO. I suggest you email XFX and they likely will send one out free of chage. I've had excellent luck with XFX support in the past.

Wait so your PSU only has single pci-e 6 pin and you want to split that into 6pin and 8pin?

I'm guessing that PSU has 2 pci-e connectors and he will use them for the 8-pin connector, then use two 4-pin molex's for the 6-pin PCI-e.

Thanks a lot for the offer. What kind of adapter do you have exactly? Does it connect all five ground wires (black ones) on the 8-pin side to the two 6-pin plugs, or only some of them?

Unforunately, there aren't any decent computer stores around here. The closest Microcenter seems to be in NYC, which is a fair distance away, and their site has nothing relevant on it.

As for the warning, I looked a bit into that and it seems that Nvidia is being somewhat overcautious, similar to what they do with their general PSU recommendations. The card uses a maximum of 235W (and typically more like 180-200W according to the reviews), which would be just about covered by two 6-pin plugs along with 75W from the slot itself. They may have included the additional power capability for heavy overclocking more than anything else, similar to what the 6800U or 2900XT had. At any rate, I figure it won't hurt to try it out. I saw at least two reviews where they used the adapter and reported no problems.

That will indeed work, but it comes out to $20 once shipping is added. I don't know why they're charging so much for something that should just come in a padded envelope.

Yes, exactly. It will look a little clumsy but it's better than buying a new PSU just for that plug. The card does come with the 6-pin/molex splitter, although I already have a couple of those.

Post some benches when you get it up and running that beast

And theres FW 177.39 released. Its the PhysX driver.

I just realized that you already had found that adapter from performancepcs....

Anyways, did you contact XFX and ask if they can send you an adapter? I beleive an item like that definitely should come with the card.

Didn't work for me. had the dual 6 pin to 8 pin Y adapter. Worked for 5 minutes then corrupted graphics followed by BSOD. Rebooting shows corrupted text on post. Replaced old video card in and working fine. Have a 800 watt BFG PS and am going to have to replace it...

I didn't actually contact them, but after searching around on their forums their official line seems to be that the adapter might work but they don't recommend it, so it's unlikely that they offer them to end users. I have not actually seen any cases where the adapter was clearly causing problems, however.

In any case, chizow sent me his adapter (should have it by tomorrow), so I should be fine for now.

That sounds bad, but the adapter may not necessarily be your problem. There is a separate issue with some of these cards where they overheat unexpectedly, so you should check your temperatures. I don't know how widespread this issue is, but there is a long thread on it on the nvnews forums. Some people there thought the adapters were behind the trouble but getting a new PSU didn't fix the issue. Seems to be a defective batch of cards.
