750W+ Power supply with good efficiency at low load

Does such a thing exist? I want one for a gaming build that is also efficient while running at idle around 50W.

    As far as power supplies go Thermaltake ranges from crap to mediocre. Certainly not something to buy unless they are all you have access to. Even more especially when it's priced higher than the best models on the market.

    What will you be running that requires 750 watts? At least 2 x GTX 670s or 2 x HD7950s/HD 7970s. With a high end system like that get a Seasonic X 750. Among the best power supplies made.

    No power supplies are going to be super efficient at truly low loads like that but the difference is small.

    This explains.

    Hi - agree with anort's assessment of TT PSU's. Likewise the X-750 is an excellent
    unit (I have the X-650) @ $145net, if you want to spend a little less, this one nets
    to $120: http://www.newegg.com/Product/Product.aspx?Item=N82E16817121088 Platinum/modular
  3. I will be getting the seasonic x750 looks to be the best! I want to upgrade to a dual GPU card in the future and also have great idle consumption.
