power splitter requirements

have just received my point of view gtx280 1024 gpu. in the box were 2 adapters for the power supply. one takes 2 four pin molex to make a 6 pin pci, the other turns 2 six pin pcis into an 8 pin for the card. the card requires one six pin and one eight pin. what i want to know is if the adpater to make the eight pin requires one or two six pin plugs plugged into the splitter? it has 2 sockets merging into the one eight pin plug, most of the wires seem to share a socket with 2 cables going into the back of one pin quite a few times. does this adapter need two six pins plugged in or just one? if it does i will have to get an adapter to make another 6 pin!
 
I think that a 6-pin connector can supply 75W of power and a 8-pin one 150W so I think to run the card at it's theoretical maximum power draw you need two separate 6-pin connectors.

But it might also work with one connected but I am not too sure.

Don't you have two 6-pin connectors coming from your PSU?
 
If your PSU only has 1 pci-e 6 pin connector, I'd be worried if it can supply enough power to the system.

If you have 2 6 pins, I dont see why there would be a problem. Use the 2 6 pins for the 8 pin and 2 molexes for the 6 pin.
 
ive got a hec win power 800watt psu. looked through the tangle of cables and only found 1 6 pin. it has an 8 pin for the card, but the cable is 2 inches too short to reach the gpu socket as the cable is also used for the 4 pin motherboard supply!
 
it has an 8 pin for the card, but the cable is 2 inches too short to reach the gpu socket as the cable is also used for the 4 pin motherboard supply!
Are you sure, I thought it would have a separate 6-pin and 8-pin for videocards and a separate 4+4 pin connector for the mobo :confused:
 
The adapter I have here uses 2 six pin plugs to one 8 pin. I have to have BOTH 6 pins in or the video card doesn't power up properly, the LED on the back stays red.
 
checked all the plugs coming from the psu. lots of 4s, only one 6pin pci-e,it has an 8 pin, but this is on a short lead connected to the motherboard plug, its then too short to reach the 8 socket on the gtx280. have ordered a couple of 4 to 6pin pci adapters so when they come hopefully will sort out the problem, then i can plug my 6 pin straight into the card and use 2 convertors to make two more 6pins to go into the 8 pin adapter and fingers crossed all ok!
