oldfart, you my friend are correct. I just checked the power supply and my HP PC has a Bestec ATX-300-12Z model. With a maximum output of 288W and 19 Amps at the +12V range. The video card I am getting, EVGA GEforce 7600 GS 256MB, requires a power supply containing min. 350W and +12V @ 18A(or higher).
Maybe, I should just upgrade to a more powerful Bestec model than the one currently in my machine? Like the one in this
. The seller even mentions it as an upgrade for the ATX-300-12Z model, which is the current one in my machine. I believe I have found the right model. The only minor problem is that the output for +12V is a max of 18 amps. The video card I am getting, is a minimum req. of +12 @ 18A so it barely passes. I will probably go after some Bestec PSU in the +12V @ 20A(or higher) range for assurance. I also need to make sure it is PCI-E ready.
