Hi.

Move on to a 600-650W PSU, the 500W is at limit.

I'd grab either of these instead:

http://www.newegg.com/Product/Product.aspx?Item=N82E168...
$50 Antec BP550 Plus 550W Continuous Power ATX12V V2.2 80 PLUS Certified Modular ($16 less)

http://www.newegg.com/Product/Product.aspx?Item=N82E168...
$70 Antec EarthWatts EA-650 ($5 more)

The op listed a 6790 (not a 6970, so 500W would be fine). If the Op had a 6990 I'd say get the 600W or higher, but for the price the BP550 would be a much better buy (modular, and cheaper).

A 500W is more than enough.

i5 - 95W
6790 - 150W
Other stuff < 150W unless you are completely loaded with HDDs and other devices. Even then, the number I threw out there is way bigger than you'll need.

Max - 400W

The Earthwatts 500W would be fine and has a decent rebate on it right now. You could get a Corsair CX430V2, but it'll only save you $10 and have less room for future expansion. They have had it on some really good sales for $25 after rebate (or less).

The BP550 isn't less. It is currently $73 while the Earthwatts 500D is $40 after rebate. (Newegg is horrible with having one price on the browse page, and another on the product page)

In fact, because of newegg's horrible update system, I actually suggested a PSU that costs roughly the same amount.

In the list view/search it shows $49.99 for the BP550, weird (unless it will update later). Although they are $50 on Amazon anyways (shipped from Amazon, out of stock atm).

For a system running with a single Radeon HD 6790 graphics card a power supply with a combined +12 Volt continuous current rating of 24 Amps or greater and with at least two 6-pin PCI Express supplementary power connectors is recommended.

You may find power supplies on the market that supply more than enough Wattage to run the system. However, many of them lack the Amperage capacity on the critical +12 Volt rail, which is necessary to support that claimed Wattage.

The two devices that consume the majority of the power, within the computer, are the CPU and the GPU. Both of these devices obtain all of their power from the +12 Volt rail(s). If this critical rail is unable to supply enough power the system is not going to run properly. So don't just look at the power supply's total wattage rating.

The power supply calculators mentioned in the above replies don't provide this critical information. The eXtreme Power Supply Calculator Pro will provide the critical PSU rail specifications but only if you're willing to pay for it.

The Antec EarthWatts EA-500D Green with its combined +12 Volt continuous current rating of 37 Amps and with one 6-pin and one 6+2pin PCI-E Supplementary Power Connectors is more than sufficient to power your system.
