    Default Bitcoin Miner Power Supplies Look Interesting

    If you search on eBay or AliExpress for mining power supplies or 90 or 95 plus gold power supplies, you'll see a bunch of these things. The funniest one that I've seen is a 3450W unit that looks like two PSUs put together. Also saw a triple combo somewhere too.

    Could there possibly be a Death of a Gutless Wonder VI???

    "Note: Do not fit 110V voltage"

    Then again, most every house in the US has 220V

    They do? I'm pretty sure they're all standard 120 with few exceptions when higher voltage is maybe needed. But normal outlets. Unless you're confusing me.

    Many houses in the US have 220v/30A outlets for dryers and sometimes other large appliances if added after the fact.

    North america input to the house is usually 2 phases of 120v that are 180 degree out of phase to each other. You can get 240v that way, that's how dryers and all get their power, because a <2kw dryer wouldn't dry your clothes

    It's actually split-phase 240v.

    Heat pump dryer with 900-1000W will.

    Thanks, I was looking for that word.

    Each phase is still 180 degrees out of phase to each other though.

    Not like you can make money from GPU Bitcoin mining in the first place, unless someone else is paying for electricity, so anyone selling ATX PSUs as for Bitcoin mining, should raise eyebrows from the beginning.

    Then why do people run rigs? the power supply, video cards and electric bill cost are not exactly small.
