Im supprised what you've currently got works on a 250W Try it, if you have instability, your pc resets or the air out the back could toast bread change it for something more powerful.
I tried running my HDD and 9800 Pro from a power splitter on one molex channel, the HDD kept locking up in games. Make sure you have a spare molex for the card.
I wouldn't risk it at all. This is one big consequence of buying big OEM (like HP). The cynical would say they use marginal PSUs to keep costs very low and prevent users from upgrading. You may also find the mobo, case and even RAM prevent normal upgrade paths too.
my dad wouldn't let me build my own computer because he thought it was more expensive so he went to costco and just bought this for me for college. it cost $1500. what a rip off. A COSTCO COMPUTER~!
