your powersupply should have a wattage rating on it, I think that should do, like 250, 300, 350 watts, something around there. Just get a really big one [IMG]i/expressions/face-icon-small-smile.gif[/IMG]

a 300 watt supply should be more than adequate

400 wat PSU = for a house = 120 volts = drawing (for the sake of argument) like 3 amps of current.

300 watt inverter = car = 12 volts = (for the sake of argument) 25 amps of current.

ya, i think you will be JUST fine.

wait, did i get my math bass ackwards? understudy! (seriously someone should confirm this)

dont forget that if ur going to put a standard, CRT type monitor, its going to draw a TON of current, and use a TON of power

sorta off topic but also an invertor question.
now i have my power invertor wired and its sittin under the drivers seat. (*intvertor is one from Interact. they make alot of video game accessories). now i also have my PS2 under my seat also. from what i understand this is the reason im getting a whining noise, since my signal cables are pretty close to my power invertor. could i just fix this by wraping the power invertor in foil? or something to that effect?

thanks
Mike
