Solved

Just tested how much power my PC is using, can I fit another GPU in?

So I am using 280w max with OCCT PSU tester on, so everything maxed out. I have the following. (Tested with a kill-a-watt meter)

i5 3570k (Stock Clocks)
HD 7850 (1100 core clock)
XFX Core Edition 550w

So I think that getting another HD 7850 is easy right?

  1. At least a 650-700W psu is recommended for CF I think.

    If the kill-a-watt meter is reading 280W at 100% load, considering 80plus bronze of your PSU, the system is actually using 230W. Maybe a tad more... 240W at most.

    Your power supply is rated to deliver 528W on the 12V rail. The 7850 easily uses under 200W (actually closer to 100W):

    I'd say with that PSU, you're good to go with another. You have a solid power supply. It's going to work.
