No, a standard computer will never peak higher than 300 Watt, even if burning
and running chess software at the same time (it's different with high-end
graphic cards). I don't recommend a 550 Watt power supply. A larger power supply
will be less efficient, if you are below 300 Watt. The power supplies work most
efficient if they operate near their max. There is really no reason to worry
that 300 Watt isn't enough.
