What power supply do I need for a Nvidia GT220 and 6150se?

I have already got a Nvidia Geforce 6150se in my computer, I want to know what power supply I need to also use the GT220?



Here's my computer: http://bizsupport1.austin.hp.com/bizsupp…|||All you need for the Graphics card is a 300 Watt Power Supply (with 18A on the +12V Rail). For what you have I recommend a 350 Watt Power Supply (with 18A on the +12V Rail). The graphics card doesn't need a 700 Watt Power Supply unless you upgraded more than just the card:)
