I have seen an article about this before, but I can't remember where I saved it.
Basically, I want to know how to add up the wattage that my computer will use at max by looking at the devices connected to each of the rails (3.3 V, 5V, 12V). I want to do this instead of just using Antec's PSU calc because I want to make sure I have enough power for the devices connected to each rail. For example, I may have enough power overall, but a certain rail may be overloaded (this is how it works right?). I've heard a lot of discussion on one rail versus lots of 12V rails and it seems like there isn't concrete answer as to which is better. If you have multiple rails does all the power work fine anyway or is there a limit to the amperage on each rail?
I'm asking because I may be getting a new video card in a few months (something like the GTX 460) and I don't know if my Antec 550 TruePower Trio is going to be enough
