Houshold amps not enough for gaming?

Im just confused about whether my homes electrical power system is powerful enough. The average houshold amps per outlet in my area is 20 amps each or combined im not sure (hopefully each). However, gaming systems with quad or dual core cpus and mid range graphics cards apparently can use up to 35Amps! Unless a home has high end heavy gauged wiring system which most people dont have how can the average gamer get enough amps for his machine? Is there something im missing? Would it be useless for me to buy a 30A rated PSU if my outlet in my room maxes at 20A? I have had a gaming system before that seemed to have ran fine with normal 3dmark06 scores and expected FPS rates but i never considered this possibility with amp supply, and it was a Q9550, GTX 280 setup.

Your machine is not going to pull any where close to 2400w.

A 20 Amp 120 volt breaker has a max capacity of 2,400w. I have an i7 920, 4870 X2, 8800 GTX and 3 HDDs and I'm not even pulling any where close to 200w at idle. I'm probably pulling less than 500 watts at full load.

Houses, in the US atleast, use 120v for the main wiring. 20 amps X 120 volts = 2,400 watts. PC components use 3.3, 5 and 12v. 500w on a 12v is roughly 41 amps. That's only, at 80% efficiency, 625 watts which translates to roughly 5.2 amps.

You're confusing AC amperage with the DC amperage the psu pushes out. You will be fine with nearly psu you get. The only thing to consider may be a UPS or a line conditioner to make sure your psu get consistent, clean amperage from the electrical outlet.freesafety13

How do you monitor the power usage for your machine, is there software for this?

I base a lot of it off of reviews for the components that I have. A i7 965 @ 3.75Ghz, GTX 480, 1 HDD and 6GB of RAM pull ~460w at full load, ~210w at idle.
