Small Form Factor PSU

[Tuffgong4]

In the next 6 months or so I'm going to build myself a new rig...I really want one of the shuttle small form factors but if you use a standard ATX board and a normal sized case and you have enough components you need a really powerful PSU. How come with the small form factor you can get away with such a small PSU in these things...Just wondering if anyone knows

I believe they usally use parts that use less wattage same as laptops do

maybe cause they dont have all those extra slots for adding more hard drives, cd-roms, etc. so you wont need that many watts, just a guess.

the lack of many drives, pci cards, and also fans helps reduce power consumption. besides, you'd be surprised what a 250watt power supply can run.
