    Not sure what it says about me but this did more to explain it than anything.

    Too many words, OvRiDe!
    “Do not trust people like me. I will take you to museums, and parks, and monuments, and kiss you in every beautiful place, so that you can never go back to them without tasting me like blood in your mouth. I will destroy you in the most beautiful way possible, and when I leave you will finally understand why storms are named after people.”

    Haha, sorry, was just feeling antagonistically pedantic that day. Math errors cannot be tolerated!

    Household electrics rated as 110V, 115V, 120V, 125V, etc, are basically all identical aside from engineering/legal/regulatory preferences. The AC power could be calculated with different weights on RMS or duty-load or impedance factors, and is sometimes derated a little by product manufacturers (or electric utilities) for whatever reason.

    The fact is that all but the cheapest PSUs can accept a fairly wide range of deviations from the household norm, and unless they're servicing loads near the maximum 1800W limits, they won't use the maximum theoretical power being offered because their entire purpose is to just provide regulated power to the system downline. An higher-rated PSU won't draw more power (or cost more to operate) when operating at lower-rated PSU loads (barring minor inefficiency losses caused by wattage-optimized engineering tradeoffs).
    My mind says Technic, but my body says Duplo.
