Check out the following article at life hacker:
Power Supply Calculator Figures Out What Size PSU to Buy

Power supply calculator is good. When buying a power supply though, if the calculator says 800W
in my opinion you should normally over do it a bit with ay a 1000W supply

Hope this helps

A 700w PSU will be fine. That rig as it stands will only draw about 500-550w

According to EVGA GeForce GTX 560 SC Video Card Review - Power Consumption - Legit Reviews, the following system uses 132 watts at idle and 308 watts under load, as measured by a Killawatt power meter. You shouldn’t be far off that.

Processor: AMD Phenom 2 965 3.4 GHz
Motherboard: MSI 790FX GD-70

Hard Drive: Western Digital SiliconEdge Blue 128 GB SSD

And always remember, a high quality, reputable brand power supply at a lower wattage will usually outperform a lower quality less known manufacturer advertising more power output.

Translated, I'd rather run with a 600 Watt Corsair or SeaSonic power supply, than an 850w TipTowTon that costs 1/3 of the 600 watt Corsair.

Most aren't rebranded Seasonics, but it seems Corsair is a moving target--they frequently change who actually does their manufacturing. So, there is no telling who might make a new Corsair PSU model that hits the market next month.

Rebranded or not, the Corsair Power Supplies are very well built, rugged and run great.

Yeah the main thing to look for is the 12V amp supply. Frequently, in order to get /enough/ amps for your GPU and the motherboard, yo u need to go with a rating higher than you might think for the rest of the system.

So a 300 watt system seems like would run fine on a 500 watt PSU. BUT that PSU only has 24A 12V rails and your video card needs 32! OOPS. (Just an example)

That being said, you aren't putting a 590 in there, I would think that a quality 800 watt supply would already be PLENTY of PSU for the computer and 560 card. I have 800 watts and am running a 480 which is like 50% more amps than the 560. But check the PSU 12V amp rating and the video cards 12V amp requirements. Make sure you got plenty there, everything else will fall in line.

It get much more complicated than that. Who built the power supply could replace murder mysteries as a great new pass time.

There are only a few manufacturers who actually build power supplies. Seasonic is one of the more well known of them.

But the Branding Reseller (Corsair, for instance) is the one who comes up with the specifications for the product they want to sell. They could specify a unit that uses all top tier components that they plan to sell at a premium price point, or they could go for an economy price point and specify cheaper components. The manufacturer will build what they are told to build. To complicate things further, loosely specified builds can also go out to bid, so the different manufacturers have some leeway in terms of what components they can use to beat the competition in a race to the bottom.

So just because a power supply is made by Seasonic does not mean it is a high quality supply. Although it is my impression and opinion that when a Branding Reseller wants to market a higher quality supply with higher specs they usually have one of the big 3 do the build.
