I have a Dell Dimension 4700. It has a P4 520 which is the Prescott 2.8 GHz CPU with 1GB DDR2 RAM. It has just the Intel GMA900 on board video. I would like to upgrade the video so I purchased a Sapphire ATI X800-GTO2 video card. On the newegg website under system requirements it says a minimum of a 300W power supply is required. I looked through the manual for the computer and it states that the power is a 305W model. The only items installed are a WD 80GB SATA hard drive and a NEC 16X DVD burner. Will this power supply be enough to power the system with the new video card. If its not and I need to upgrade the PSU does anybody know if a standard PSU will work in my Dell. I know at one point Dell mobo's didnt use standard plugs, they had a proprietary plug setup. Thanks for your help.
