Not even close I'd recommend a corsair builder series 500W psu if you're on a budget. Secondly why would you want a last generation card? Unless you're getting it for a great deal you'll be better off with a newer card such as a 7850 or 7870. http://www.newegg.com/Product/Product.aspx?Item=N82E168...
Well andrewcarr those GPUs are nice but as he is aiming higher i assume he is gaming @1080P. So 1GB ram will struggle on that resolution.
The XFX i linked has lifetime warranty and 2Gb Vram for a good price(1$ less). 179$
That Cx 430 V2 is good but i discovered Antec Vp450W was better than it.(I hvnt tried yet that Antec but reviews (hardwareecrets) gave golden award and it delivered more W on 12V Rail than Cx 430 V2. And its just 30$ making it a better deal than Cx 430 V2.
That PSU is also a good one that I wasn't aware of, good recommendation (although since you can't order a PSU when it isn't in stock I don't see point of adding that).
Lastly 1 GB really isn't as much of a hindrance as most people make it out to be. If you look at the previous generation of cards most didn't have more than one or slightly more than one GB. Only place I see him maxing it is at very high AA or possibly many mods in games such as Skyrim.
Every possible setting was maxed. I'm not disagreeing that the 2 GB version is better I'm just saying that under current normal use it's okay to have 1 GB since at what setting most people run AA won't be maxed on a card that's not top of the line. Also in opposition to the 560 Ti he listed either version of the 7850 is better.
To quote myself
"Only place I see him maxing it is at very high AA or possibly many mods in games such as Skyrim."
Those tests were with the highest AA. I wouldn't recommend CF with 7850 1 GB but if you never intend to do this you'll be fine. His low end motherboard doesn't even support CF.
