8 x PCIe power connecotors - how

[vivithemage]

What's the best way to do this? Most PSU's only come with 4, and my 4x5830's need 2 each.

What are most people doing to make this work with one PSU?

Molex -> PCIe adapters. Your cards most likely came with some.

[vivithemage]

I have never seen cards come with molex to PCIe.

He's right, they only come with older cards. I got a bunch with 5830's, but never with anything more recent than those.
Even then it's manufacturer specific. Diamond could give two, Club3d/sapphire one, and others either one or nothing.

Newer cards just have 2x6pin to 8-pin adapters.

You could see if Cablesaurus sells them, though.

my 5830s came with 2 each i think, off to check the boxes i go

edit: yep 2 adapters in each box i am assuming since the first box had two in it. its even in the pics at newegg now that i went there and checked also

I use a shielded version of this that I picked up locally.  

If you need 8 pin adapters its just as easy to adapt one 6 pin to one 8 pin.  Since the other two pins are merely grounds it doesn't make a difference if your PSU's rails can support the output needed.

That's not completely true. They don't come with "newer" cards because the more recent cars use 8 pins. Any card uses 6 pin should come with the adapter.

I've seen them every time I've opened up a new 5830, 5850, 5870 from various brands.

Good to know, i'll use those

My Vertex 3D (it's made by Powercolor) HD 6850 came with no molex -> PCI-E connector, but both of my Sapphire HD 5850s came with 2 each.

Yeah, I think the last $109.99 5830 I got from NewEgg had them.

Do I need dummy cards for the other video cards that are not running on xfire? I have this mobo :

No, not with the 11.7 drivers.

[vivithemage]

sweet

Where can I get 11.7?

Actually, I bought an XFX 6850 brand new and it came with nothing, no cables, no adapters.  Just the card, a CD and instrution manual.

XFX fail

My cards never came with an 8 pin power adapter, and local store didn't sell them.

I tried powering it with 2 pin connections, instead of the required 6 pin + 8 pin, and seems to work fine.
