Is my Corsair GS600W too little? I have 2x 7950, i5-3570k, 2x4gb ram, 120GB SSD and 1TB hard drive, optical drive and 3 fans on the case. I currently have no problems with my system but I want to replace the stock fan on my CPU and I'm afraid that I'll push the wattage too far. According to wattage calculators I need around 500 wats, but I'm still paranoid.
On a side note, I'm thinking about a Corsair hydro H60. Worth it?
