Overclocking help

Need to know the PSU and the fans in the case.

How do I find that out?  

Open the case and read the PSU label, or post a picture. On the fans, I just want to know how many and where.

Sorry about the image quality, I don't have a great camera =/

The 460W version of that PSU got a very negative review, and I would expect the 500W version to be as bad or worse.

If that is your only case fan, you need to add some. A couple 120mm fans, one for the front and one for the top.

Replace your PSU with something safe and efficient, that will provide power that is stable enough for your card and CPU.
