Difference between 300 and 250 casings

[hyborn]

Building a desktop PC, does it need to have a 300 PSU as standard?

Or will a 250 suffice?

bit of a newbie here still, would appreciate some advice

:)

General rule of thumb - as large a PSU as possible. the difference in price between 250 and 300 is negligible so go for the 300.
