  1. You need to get a new PSU defiantly.

    And a good quality one and 650W.

    Seasonic Focus Plus
    Corsair RMX
    EVGA G2 or G3

    That GTX 1080Ti can pull well over 300W.

    Are you sure it's not an adapter to make TWO 6-pins into an 8-pin?

    Making a single 6-pin into an 8-pin seems like a terrible idea, in a fire-hazard kind of way. 8-pin is meant to supply up to 150W of power, whereas 6-pin is meant to supply only a maximum of 75W.

    Potentially drawing up to 150W over wires designed to carry 75W is a disaster waiting to happen.

    I'm in full, 100% agreement with jankerson.

    I suspect they are referring to something like this...

    You actually need to buy a new PSU.

    Otherwise you risk damaging the GPU and or you whole system.

    Best to replace it.
  7. That 750 watt Antec should most likely be fine. It has four 8pin (6+2) connectors, and should offer plenty of capacity.

    That's not the one he has...

    He has the old one with 1x 6+2 and 1x 6 Pin...

    It sounds like they are referring to an extra drive that they have, different from the one that was in their system. So long as the drive has at least a couple 6+2 pin connectors it should likely be fine.
