Why can't I just do this?

(I actually think I can...)

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?).

get an other riser, powered if possible and an other small power supply and look how to join it to your existing 24 powerplug so that it will turn on and off like your regular powersuppply

I would like to add a 4th card to my rig, a 7970...

Currently rig:

Graphics Cards Gigabyte HD7950 3Gb GD5 (X3)
Processor AMD Athlon II X2 Dual-core 260
Hard Drive WD Blue 500 gb
Motherboard Asrock 970 Extreme4 $99
Power Corsair 1000W ZX Series GLD
Ram Kingston 8gb (2x4)
Case Coolmast HAF XM MIDTWR ATX CASE

I have 2 PCI x1 slots on the 970, so I can run the 7970 into one of those with a riser card extender... but

How do I power the 7970?

all of my PCIE slots on the PSU are taken.... what are my options?

A) Daisy Chain or get a splitter of some sort **
B) Get a separate power source?
C) Nope I'm fucked and I'd need to get a new PSU
D) Other ________

A)** something like this but longer: will this be problematic when mining?

EDIT: It doesn't need to be longer because I can just plug cables into the end to extend it, right?
