Are you asking about Corsair PSUs or the 850w unit in your signature?

i was just wondering if i needed to upgrade my PSU or if the PSU i am using now should be fine

In our stickies here in the PSU section, you can find our PSU Finder. http://www.corsair.com/psufinder/default.aspx

Plug your specifications into it and compare the recommended PSU with your current PSU.
