    I'm looking to upgrade my Graphics card from a GTX 760 to a GTX 1660.

    I noticed that my existing GTX 760 needs 2 6-pin power adapters and it says that it requires 170W of power, but the GTX 1660 says that it only requires 120W of power.

    A newer more powerful card needing less power than my ancient 760?

    Is the GTX 1660 using less power because it's newer and more efficient, or am I misunderstanding the 1660's power requirements and it actually needs more power, or it gets other power from somewhere like the motherboard?

    You almost answered your own question. It is more power efficient. Certainly when compared to older cards. It's a smaller card too compared to others so I'm guessing it does not need to slurp as much juice.

    Yeah, but I needed to be sure.

    I'm surprised it's that low to be honest mid range cards are normally 150w range

    This was one of the reasons that I thought that I might have made a mistake. My ancient GTX 760 uses 170w and needs two 6 pin plugs, so I wasn't sure that I'd gotten the right numbers for this one. I think that it must simply be more efficient.

    It makes sense when you consider the card will get 75watts from the pci slot and 50 from the power connector
