Right now I have 150 watts max power power supply.
Heres a pic of my power supply specs.
I do know that my motherboard doesn't use much power since it's an older machine so I was hoping that at least the ATI Radeon 9250 or GeForce FX 5200 or so will work with my current 150 watt power supply.
I would save alot of money for me if I can use my money on just buying the ATI Radeon 9250 or the GeForce FX series or maybe the GeForce 6200. I will be using a PCI type card since my motherboard doesn't have an open AGP slot.
