I'm considering running 220v to my PCs because a) it would be easy and b) its more efficient. However, there doesn't seem to be any consumer grade UPS for 220v. I'm used to being able to get a 750 VA UPS for < $100 (sometimes on sale for $35). I don't see options like this for 220v. Is anybody else using 220v in the US and what do you do for a UPS?

    I use them. They are commercial or high-end consumer. They cost much more than your example above of roughly $30 on sale. They can run into the low $1,000 range, but you can get a consumer grade one for $800ish. It does allow for multiple PCs to run off the same UPS since the Wattage would be around 1800W+ per unit. If you are only running one PC, 220V is overkill. Stick to the options you have used in the past.

    Expand on what it is you are doing with your computer that you want to run 220VAC here in the US?
    With only the need of a 750 VA UPS I do not see how you are going to save any money going under 220VAC

    Not looking to save money, just considering a fun project to be slightly more efficient.

    My Projects was to setup computers with Two Power Supplies and Two UPS Units.

    Same thing I was thinking, the PSU accepts from 110VAC through 250VAC and is slightly more efficient at 240V or 208V (Server UPS).
    The question is how to set it up.  Solution seems to be an outlet with 2 hot and neutral through the ground pin.  Gotta flag it though as it will fry anything not designed to accept a higher current.
    I wish EVGA would sell a cable to work with a standard US Dryer outlet, but the connections are the same 2 hots and a Neutral with no ground.

    You can not plug a 120V device into a proper 220V socket

    It will work. Should you do it if you think the mains is 220v when it's really 240v? No, you obviously haven't studied up enough to do so safely.
     
    NEMA to IEC is doable and would work on a computer power supply. Cable like so: https://www.stayonline.co...5-power-cords-9302.asp

    Yes but EVGA doesn't sell a cable that works with the official outlet types allowed for 220V operation. So the easiest solution is rewire an existing outlet or buy a specialty cord and outlet. I think evga should sell 220V cables for their PSU products, especially the higher wattage ones.

    In my area mains actually spit out up to 125V or more. I've seen at least 125V on both a multimeter and UPS status panel.

    117 is the "nominal" voltage under the NEC - 5 volt variations are common, 10 volt is fairly uncommon outside of "brownouts".
    125 is rather higher than I've normally seen, but it's within spec. You're probably right on top of a substation.
    There are quite a few sources for NEMA 6 to IEC power cords, though they all tend to be quite expensive compared to the "common" NEMA 5-15 to IEC type cords normally provided and used in the USA with power supplies and other computer hardware for consumers.
     

    Now that vorsholk has stopped his abuse, I'm returning to folding.
     I no longer MOO due to abuses by certain "whales" in the Gridcoin community - so I now work the Distributed.net project directly again.
