hey guys..instead of using a shutdown controller and a power invertor..im gonna buy an opus. only problem is...my computer is gonna put out 165 watts according to this power supply calculator. What is one to do

only thing i can think of is possibly not including the dvd player which puts off 25 watts....and mount it in the glove or somewhere else..which may be an option but i donno...anyone have an idea
thanks
Jason
