I'm running a system with 4 x 6970 (which require 1 8pin & 1 6pin each) and I'm using a Silverstone Strider 1500W. The PSU has 4 pcie cables with a 6+2pin and a 6pin.
My motherboard is an MSI 890FXA-GD70 for AM3 socket, that has 5 pcie slots(but 4 that can be used with a 1 slot gap for dual-slot GPU cards) and my case has 8pci expansion slots on the back.
So its fairly easy to run a 4 card setup even if those cards are dual slot.

I use MSI 790FX-GD70 Socket AM3, that also has 5 pcie slots (4*x16,1*x1 physical size). Also I use 2xChieftec APS-800C connected with each other on green powerOn signal cable and black ground cable. Works like a charm.

TJ11. got it cheap and love it. it has a fantastic design and I'm able to close the side panels with appropriate amount of fans for proper heat/airflow dispersal. with more GPUs being supported by 11.6 drivers, I will be adding more cards in the empty 5.25 bay... there's plenty of room to "hang" them there...

I have 2 ST1500 for 4 6990s... I'm in the process of adding a 5th one.
This ain't cheap...

I hear the Corsairs' cables are too stiff and not long enough for a bottom-mount case.

I want to both mount on the bottom, AND route through the back of the motherboard.

Amazon has the Coolermaster Silent Pro Gold 1000w PSU for around $199 in stock. Heres a link:

I am running 3 5850's and a 5870 in my rig right now, and I am powering it with a 850w Corsair. Heres the link to it:

Its a damn good PSU.

Note that these aren't splitters, they're just adapters, and they come with the cards, so presumably they're safe to use (otherwise Sapphire wouldn't ship 'em?).

Noted. I never thought of adapters!! +1

Im using this http://www.coolermaster.com/product.php?product_id=6662 . It has 8 pci-e connectors, 1000W and is powering 4 OC 5870 with ease (a total of 805W).

Pretty cool. I'll have to google the price. +1

Im using this http://www.coolermaster.com/product.php?product_id=6662 . It has 8 pci-e connectors, 1000W and is powering 4 OC 5870 with ease (a total of 805W). It has an efficiency of 90-92% (which is an important factor if you are going to run it 24/7). Its very quiet too, but this is not important in this case with the 4 cards making a lot of noise.

Worth the money.

I'm running a 4x5830 Radeon setup (each of which takes 2x6 pin PCIe power connectors) off a Corsair 850 Watt PSU. The PSU only provides four 6-pin PCIe power connectors; however, it does have a lot more 4-pin Molex power connectors, which I've plugged four of the Molex-to-PCIe adapters that came with the videocards into. No issues there. Note that these aren't splitters, they're just adapters, and they come with the cards, so presumably they're safe to use (otherwise Sapphire wouldn't ship 'em?).

The best video cards need TWO (2) 6-pin power connections, and it is NOT recommended to use Y-splitters in any configuration.

I don't know of any power supply units (PSU) that have more than six of those 6-pin power connections.

How do you mine with four physical cards in a self contained rig (not a rack style multi-rig)?

Thanks for your time.
