I had this problem when I started out with the same setup. It turned out that my no-name 400W ATX power supply was SUPPOSED to be supplying 20A on two separate 12V rails but was not. I switched to a $50 500W Antec which seems to be performing as rated. Punchline: generic power supply manufacturers may lie about their current rating.
Also make sure you're using BOTH 12V rails. Usually there is a high-current 4-connector Molex for a separate high-current 12V connection on a graphics card, which is (often) a separate rail from the 12V supply to hard drives and DVD drives. Some power supplies tell you which connectors are on which rails but they should generally follow that convention.
If you connect both 12V rails in parallel you should get the maximum current supply. I prefer to keep my heated bed on a separate rail.
