SilverStone 400W ST40EF
 

With power supplies pushing the stratosphere of over 1000 watts we lose sight of the needs of the basic user. If your system isn't bleeding edge with terabytes of storage, SLI or Crossfire and a pair of power hungry processors you really don't need tons of juice. If you're like the majority of users out there with a couple of hard drives, a burner or two, a single video card and a dual-core processor you just need a simple, reliable power supply.
