How to upgrade my power supply?

Hi I am 14 and this is the first decent computer I have ever owned. I am an avid gamer and my 128MB graphics card is awesome, but i would like to upgrade to a 256MB. I have an HP and it is not necesarily a gaming computer, meaning its power supply is not very impressive. The card I want to buy (ATI X800 PRO) requires 350 watts or more or it could overheat. I was wondering if/how I can upgrade the amount of wattage my computer can handle. Also, is a power supply a stand alone unit that is hooked up to the computer or is it a component that requires you to install it directly into the computer? Any help would be necessary and sorry for the huge letter.

In order to upgrade the power supply, first you will have to look at your system board manual to see the maximum amount of wattage it can handle If the amount is sufficient, you may go ahead and install the new power supply unit and video card, but it is advisable that you also purchase cooling fans Therefore, you do not have to worry about your system over heating.
