I have an A1200 that I am putting in a custom tower. The power supply I am planning to use is 250W. How many harddrives, CD-Rom drives, etc. will I be able to safely power? Is there a "rule of thumb" as to how much power is used by a harddrive, etc.? I don't want to under power the tower, yet I believe when the Amiga BigFoot power supplies were available they were also 250W.
