You mentioned R9 280x in the body of the post, and R9 290x in the title and tags.
I have around the same parts with the R9 280x, and a 750W PSU, which is more than I need.
The estimated requirement for your build with the R9 290x is 470W, so 700 - 750W will be safe.

You can run that system easy starting with any 550w certified 80+ bronze psu or higher on up wattage psu but look for a good gold or platinum certified psu seasonic corsair etc depending on your psu budget or noise level fans hybrid fan mode or whatever features you care for your future psu to have Wattage wise starting from 550w and you are fine can go higher like 650 or 750 if u want to sli/crossfire in the future.The tendency in new video cards its power eficiency just look at the new gtx 980-970 cards that need less and less juice to run so the era of monstrous psu is over

Sooo, if he will burn any parts based on low wattage, will you pay the price for them?
Based on the below link, it`s recommeded a MINIMUM of 550-600W for the R9 290x, without any OC on the GPU or PSU:

OP, don`t cheap out on the PSU. It`s the only component that can damage other components in your PC.
I dont understand why u jump at my neck like that ))) if u cared to look at your link test u posted and really read it u would see that the system had room of about 150w to the max 550w i recomended and keep in mind that your test has a 290x in it not a 280x that the OP has 280x eich is less power hungry so therefore more headroom to the max 550w psu minimum that i recommended so where am im wrong ? Furthere more i ran a much more power hungry system than the OP's with a Corsar VX 550w psu for 5 years without a problem even in stress tests not to mention video games it ran a power hungry amd phenom x4 965 quad 8 gb ram3 hdd 3 fans and a ati hd 3870x2 dual core card and system was overclocked the psu is still running fine after i sold it in a friends intel i5 build runing a gtx 760 even after 6 and a half years of lifetime. So i based my answer acording to my own experience building systems and even if u count in the psus choke degradation in time as long as it is a good quality psu with at least 550w gold/platinum psu there is no problem running the system and that link you posted only confirms what i recomend

The thing is that the OP never clarified what GPU he has.
In the title of the thread he mentioned the R9 290x, hence the link.
I don`t want to jump to conclusions that he "surely" has an R9 280x. Based on this, and the fact that he mentioned OC`ing, I would not recommend him a 550W.

If we use the extreme outervisions psu calculator for the OPs build with a 290x in it comes with a recomandation of 519w if op has 280x than it will be lower. OP although asked what to chose between a 700 or 750w psu if he is stuck on these two i recomend the 700w as its the lowest. Furthermore a thing that must be taken in acount is alsow the power eficiency of the psu acording to load. There must be taken in account that if we use our pcs for web or games or work etc it would never come close to full cpu+ gpu load or max power consumption as the sintetic test are done keeping this in mind if your system uses in idle about 20w -30w the psu has best power eficency at a certain load say like 80% load for exaple if u have a 80% bronze psu with a 100w load that psu will draw from the wall 120w for every 100w pumped out but that 80% is only at a certain specific load every psu manufacturer has a graph with the eficiency curve . To achive the best operating costs the psus must be matched to the load
