...as not all power supplies are created equal. A lousy 450W may be no better, or even worse than, a good quality 300W.

Also a 450W is more likely to be needed in the future IF you plan to move to a dual-processor platform, and/or plan to have your case decked out with a lot peripherals (e.g. 2 or 4-disk RAID setup, separate DVD-ROM and CD-burner units, lots of expansion cards, etc.)
