for numerous reasons... you may have 4 hard drives, a lot of fans, other devices... 500W would be the safe amount... + PSU degrades... so if you buy a direct amount.. well it will output 20% less in 2-3 years...

another good reason, buy more than you need... a power supply is more efficient at 50% load... I would say, let it be not more than 70-80%... more efficient means that it will generate less heat (electricity lost to heat)....

so manufacturer isnt accurate for good reasons, and you can go lower, but not too low
