You got me there point noted.
 
Feel free to correct me if i am wrong but As much as the power (Watts) requirement matters, the current requirement, measured in Amps is as important if not even more important. This is especially true if you have a or several dedicated video card(s). As a general rule of thumb, you’re aiming for the highest number on the 12V line.
