My System Specs

AMD Radeon HD 6790 1 GB Review - Page 20/26 | techPowerUp

both videocards will eat around 250 watts at stock, in regular gaming sessions.they can go up to
300 or a bit more on some stress apps,if overclocked etc.

dont think youre pulling more than 200 watts even with the overclock with the rest of the system, so
450 watts on the 12v rail tops,in normal gaming sessions,once again....:)
Not sure what you mean by which truepower it is but it says switching power supply. As for rails, I looked at the side and it says the max output is 54A for the 12V rails, and for 3.3V or 5V rails the max output is 170W.

So you are saying 300W at most for the SLI GTX460s even if it is slightly OCed? On the PSU calculator site it told me 160W for my overclocked 2500k so including the fans, hard drives, and watercooling pump, I'm also guessing it should be around 200-250 watts. So roughly, it should be around 550-600 watts.

Now I read somewhere else that it is not good to have the PSU running close to maximum capacity and always better to leave some headroom. Is this the case?
