What does his computer use as paripheals?
If he is a major gamer or video editor, and has a 256MB onboard
ram on his Video card, and a 2GHZ or higher processor, I would suggest getting a 450W+ power supply - I live near CompuTime(from
http://www.pricewatch.com) and am able to get a 480W for 29.99 where-as at Best Buy next door, it would have cost 149.99.
go the pricewatch to get a good idea of what to pay, and heck - you can even order from the places online. Don't pay more than 35-40 dollars for a
PSU - even that is high end price.
as for the link - it doesn't work fully try again.
