$72 after shipping, u said u will use for 7years (in another post)and as time goes ur psu craps out and this gives you some headroom bro. Also dont wanna be dangerously close to the amount that is dumb,
when stressing that card can get 250 watts, and the cpu will waste around 130 when at load, so thats 380 not including drives, fans and other stuff, 600w should be save on corsair. i wouldnt trust 500w myself
That's a budget unit is made by CWT (Channel Well Tech) and base on the DSA platform. Due to the 40A on the +12v, it's more like a ~500w by modern standard. The Superflower 450w unit that the Rosewill 450w is based on it is a high-end premium unit that is superior than the CX600 in electrical performance, efficiency, build quality, functionality (modularity), warranty (Newegg misadvertised and the CX600v2 a 3 year warranty base on their site vs the 5 year warranty of the Rosewill, which Newegg also misadvertised as shown on the image of the box).
If you are using
this graph to get your value (seeing how it got up to nearly 250w), do realize that it already included an OCed i7-3960X platform and that number is drawn from the wall (meaning you still need to factored out efficiency).
Here's a link for you:

Using a $1500 unit like the Keithley Integra 2700, they measure the GTX670 power consumption at DC output to get 167w during Furmark. Now on an i7-2600 non-k platform (which mean he isn't going to OC it, a
review shows that it draws ~156w from the wall. Let's say it's 85% efficient (which most likely lower considering the load). 156*.85= ~132.6w at DC output. Meaning that's ~300w according to that with an idled 5870 during stress test condition of both the GPU and CPU. Typical load will much lower than that, especially when merely using as an HTPC.
