I might change my PSU in the summer, would 850W be overkill?

Here's my build as it is right now

And here's a possible upgrade plan for it (I'll upgrade the GPU and RAM later, possibly in a couple years)

Anyways my plan is to add a more capable PSU around summer so I can keep up with more power hungry GPUs which will come out later and to add an aftermarket CPU cooler so I can do overclocking. Would 850W be overkill even for the next generation of AMD's high-end GPUs? I'm thinking by the time I need to upgrade my GPU AMD would have come out with an HD 8000 or 9000 series (I'm just putting the 7970 as a placeholder, I'll probably change it when AMD comes out with their 8000 series).

Yeah my Dad doesn't want me to do any of this until I actually need to upgrade the GPU because its working fine right now. Its just that I want to get the CPU cooler so I can do overclocking and so I can get the PSU and cable management out of the way, which you can see is haphazard in my build.

850 is an overkill for just a 7850, or even a single 7970. 550 w/ a 7970 would be close, but fine.

Yeah I know its overkill right now. But would an 850W PSU be a good upgrade for future GPUs? Because I'm thinking that AMD's HD 8000 or 9000 series when it comes out will take up more wattage than my current 550.

I'm going to be running an FX 6300 and I chose a 750w to be ready for the Steamroller processor I want to be 125w and the 8000 series graphics to pull more. It should be enough.

Maybe a little more than your 550, but not really enough to justify 850 unless you're doing a multicard setup.

The 8000- and 9000-series (and onward) are actually more likely to use less power than the 7000-series. As it stands, 650W is probably the most you'll ever need for a single-GPU setup (as well as most low-end multi-GPU setups).

So unless you plan on grabbing mutliple video cards, I think you'll be just fine with 650W - the trend is genrally towards lower power consumption.

So to be safe should I get a 700W or 750W if 850W is overkill for the 8000/9000 series? I don't think I'll run a crossfire set up. There's not really enough room for a second GPU.

By "650W is probably the most you'll ever need" I meant "a 650W power supply is the most you'll ever need." (Read through this)[http://www.anandtech.com/show/5261/amd-radeon-hd-7970-review/27]; at load, their entire test system with a 7970 drew less than 400W.
