    Thanks Johnny.
    So ranking power supplies by price-point and functionality can be done after all.

    Well, so far these are all 80 Plus power supplies (except the Corsair, but that's based on Seasonic which has every one of their models 80 Plus certified) that I'm familiar with and approve of.

    I'm glad you took the time to make out this list.

    I think many people waste a bunch of money on over-buying PC components for what they are really going to use them for in their own computers.
    Sure, we would all love to have the latest 1,200 Watt monster from PC Power & Cooling (and they do sell wonderful power supplies), but after a certain point most people are just wasting money chasing wattage numbers.

    I would like to see an article on how much power supply the average and "enthusiast" user really needs.
    I'm sure many here would be surprised in finding that out for real by someone that is not a fanboy.

    Look over at SPCR in the power section, as that work has been done for mid-range systems.


    OP, What about the Enhance ENP-5140GH you reviewed?
    Worth a good looking over. http://www.badcaps.net/

    I could add. But remember: I said they were all 80 Plus certified, except for the Corsair. I know the Antecs you mentioned are all Seasonics, but they're cheaper models and probably would not pass 80 Plus.

    Yes. I also plan to update prices as they change, so any input from folks about dropping/rising prices is appreciated.

    Yep. I should add that as well.

    Hell, I remember when we couldn't get them to invest $50 in a PSU!
