    Well I plan to use a better graphics card which will require really smooth power so 1300W @ gold or Platinum should in theory use less power consumption than a 750W being Thrashed.

    Here is my latest choice as read a bad review about the Antec 1300W:

    EVGA SuperNOVA G2 1300W Modular PSU/Power Supply LN71876 - 120-G2-1300-X3 - Scan.co.uk
    620 watts ( minimum) to 750 watts ( maximum) is all you need for 1 single graphic card setup with plenty of room ahead for overclocking.

    You only need 1300 watts+ if your PC have custom water cooling, and 3 or 4x GTX Titan series overclocked.

    I recommend the Corsair RM750i or 850i.

    May I ask why you think you need 1000w? Have you tried putting your components on pcpartpicker.com as it will tell you the wattage used.

    There's also another "problem" with overpowering, power efficiency rating comes into use only at 50+% of PSU use so if you use much less it will be just drawing inordinate amount of power from socket.

    I have done electronics for well over 30 years & can not see how a psu will draw too much power if it is not using it, & switch mode does not really use any of the secondary power the pc setup would draw the current from it & they don't use large caps due to the high switching speed.

    I have used part picker:

    My PSU Choice now:

    EVGA SuperNOVA T2 1000 Watt Titanium Modular PSU/Power Supply LN69316 - 220-T2-1000-X3 - Scan.co.uk

    According to this chart found on Wikipedia 50% usage is max efficiency.

    Wikipedia is not a reliable source anymore for logic understanding. Your choice is rather waste of money for a single graphics card setup, you could save over well $90 or more for another 128GB SSD for video editing or store additional games. No single graphics card will go to use that much of power, even GTX Titan X Pascal only use >300 watts while gaming and bechmarking. I recommend you to watch this video to educate yourself because this video well suit you for oversize power supply you needed.

    Didn't I say that, LOL. I think "inordinate" is a little strong, especially for a good quality PSU. It may mean, for example, that you operate at a silver or bronze efficiency for a gold rated PSU - you would be better off spending money on a lower power, lower rated PSU if you are going to do that.

    I bought an 850 Watt Seasonic X because it was on sale and cost less than the 750 or 650 W. I have sort of regretted it.

    That is a chart for the requirements a PSU must meet to meet the standard. Good PSU have close to peak efficiency well below and above 50% of capacity.

    see for example:

    Why do you regretted it? Seasonic is very good, and that 850 watts can handle SLI.

    Because most of the time I am running less efficiently than I would a 650W. I don't regret the Seasonic, it is a great PSU, just the wattage, but it is not a big deal. .
