Nvidia GTX 280 power question

  1. Im about to purchase a nvidia gtx 280. i have been given conflicting advice over how to connect the power.

    The card requires:

    1x6 pin pcie power block.
    1x8 pin pcie power block.

    My 850 watt power supply has these connections spare.

    4x molex
    1x6 pin pcie power block

    The card comes with these adapters:

    2x molex to 1x 6 pin pcie block.
    2x6 pin pci block to 1x8 pin pcie block.

    My question is do i need to plug TWO x6 pin pcie blocks in to the adapter to create just ONEx8 pin pcie block? and the same question for molex to 6 pin pcie?

    The man im buying it from thinks 1 will be fine and plugging 2 in may fry the card, my brothers gtx 260 however has 2 molex plugged in to an adapter to create a single 6 pin pcie slot.. any help or advice would be great:)

    Thanks in advance.

    Yes and yes. Your power supply needs two 6-pin pci-e power connectors to run that card. Two by 6-pin at 75 watts equals one 8-pin at 150 watts.

    Sorry for the late reply. i decided to go for a bfg geforce 275 instead.

    it was slightly cheaper, came with a better warranty, and takes just 2x6 pin pcie blocks :)
