PSU good enough for Radeon 6670?

[Ceyd]

I hear that you're supposed to have at least 400W for your PSU to power a radeon 6670. My PSU only has around 280W and I have no clue how to check the 12 volt continuous rating. I have a IdeaCentre k320 desktop by Lenovo. I was just wondering if I do need a PSU upgrade for this new graphics card if you guys could recommend me one that will work well with this graphic card.

Would this be a good enough PSU?

either one of these would be better:

both are cheap, much better than the one you listed. both are suitable for running radeon hd 6670 (or even higher).
if you want to check +12v rail's amps rating, look at the psu label, it should be printed on it.

not really this would be though Antec VP-450 450W ATX 12V v2.3 Power Supply $37.99 http://www.newegg.com/Product/Product.aspx?Item=N82E16817371045#top

Antec VP-450 is among the best priced sub $40 PS out there.
