litecoin need more power because it uses memory, but bitcoin uses no memory so you need less power.

IMO you never have to much power  Grin

Mine hard!
Let me jump in and say I'm using three 7950s, each with 2x6 pin connectors, with an 850W Gold rated PSU. You're missing a few cards!

The cards should come with SATA or Molex to 6-pin PCIe converter cable, no?

OK, so it doesnt matter when i use one cable for each GPU?? (Of course using both 6-Pin leads of that cable)

Yeah i know its an overkill. I am thinking of running 4x7950s.

5-6?? Really? I thought each 7950 needs 200W and 200W is as safety/mainboard etc. ?

You could probably fit about 5 or 6 7950s on a 1200W PSU (assuming you're running with a Silver/Gold/Plat rating).

they (the 2* 6 pins) can come from any source, the same cable is ok, even 2 molex adapter,  anyway 1200W is overkill.

you need to connect 4 plugs to your cards. It doesn't matter which ones, as long as they are supposed to be connected to a PCIE GPU

each card requires you have both 6 pins plugged in to the car

Hi there,

i have got two 7950s and a CoolerMaster1200W PSU.

The 7950s have two 6-Pin entries and the leads from the PSU have 6-Pins and also another 6-Pin going out from those 6-Pin. (I hope its clear what i am trying to say.)

Do i have to put two single 6-Pin leads on every GPU or just one and use this extra 6-Pin for the other entry of the GPU?

Hope thats not to confusing, maybe i find a pic.
