hey guys

i know the 4770 card min requirement is 450 watts but how much more watts generally in a power supply should you have for just in case scenarios. i dont want to buy like something thats overkill but something that can withstand anything to be on the safe side..far safe. i own a rosewill green series. specs below. im just wondering if i buy a 4770 to pair it up with this 530 psu.. would i have longevity without any problems ever or do i need to upgrade the psu as well. thx guys
