  1. Yes.
  2. Best answer
    If the sockets are there, you need to use them.

    Having insufficient cords is generally a sign that your PSU isn't up to the job.
  3. The GPU has rated power maximum power of 175W.
    16x PCI-E slot ca provide 75W.
    6-pin PCI-E auxiliary connector can provide 75W.
    So yes, this card requires two 6-pin PCI-E auxiliary connectors.

    If your PSU is rated at 34A or higher on the combined +12V rails, you should be fine to use molex to PCI-E power adapters for the extra connector if your power supply doesn't have it.
