you should be good. you wont exceed more than 250w with that setup. even overclocked you still have headroom.

Do you think that this can run my power supply for just at least a month safely?

I have actually done a lot of research on this because i was thinking of getting the same PSU and GPU. Your not going to have any problems with the i500.

First, Corsair is the best PSU brand but CM is decent.

The CX500 and the i500 both have the same amount of amps on the 12v (38A), the requirement is a 500W PSU and 20A on the 12V, so you have an extra 18A on both PSU's.

But the i500 comes on top because of efficiency. The i500 is 80 plus bronze certified, the CX500 is 80 plus standard certified. Want proof? here it is from the company that certifies PSU's.

CX500

i500
http://www.plugloadsolutions.com/psu_reports/COOLER%20M...

80 Plus Standard has to have at least 80% efficiency on 20%, 50%, and 100% CPU load.

80 Plus Bronze had to have at least 82% efficiency on 20%, and 100%, and 85% efficiency on 50% CPU load.

So the i500 actually is better performing than the CX500. But slightly (almost none) worse quality.

Even on a CX430 you could run a 7850.

Edit: I almost forgot, sometimes the company claims 80 plus when its not, Even the retailer.

Hoped this helped.
