I have an IBM s51 8171 SFF with a 225W PSU. There is apparently no upgrade PSU available (probably due to the age of the unit). In addition the on board video does not have DirectDraw, Direct3D, or AGP Texture accelerators available. My question is will a H3823 Dell ATI Radeon X300 SE 128MB PCI-E X16 DVI Video Card w/ Dual VGA Cord, available on ebay, work on my computer with its small power supply. The seller said the H3823 Dell ATI Radeon X300 SE 128MB PCI-E X16 DVI Video Card was pulled from a Dell system with a 250W PSU. I am frustrated. All I want to do is hook up my Orion VR0419 VCR via a coax cable so my grandkids can watch vegietales and such like on my computer when they visit. Any help will be greatly appreciated.
