XPS 430 Won't recognize new Graphics Board

How do I know which boards the 430 will accept?

I have the XPS 430, and needed replace the old graphics board which went out. I purchased the ASUS HD 6450, however it seems the computer won't properly recognize it, and thinks its a "standard VGA card".

It does require PCIe slot, which the 430 has...

the only thing which may be an issue is that the new graphics card wants a 450w p/s, and the original one is 375 watts. Would this make it work in standard vga mode, and not the higher end graphics mode?

Standard VGA means you havent installed the RADEON Legacy Drivers.  Current Drivers DO NOT and WILL NOT work for the Radeon HD 5000 6000 7000 8000 series because these cards are end of life.

AMD Radeon™ R5 235X, Radeon™ R5 235, Radeon™ R5 230, Radeon™ R5 220, Radeon™​ HD 8470, Radeon™ HD 8350, Radeon™ HD 8000 (​D/G variants), Radeon™ HD 7000 Series (HD 7600 and below), Radeon™ HD 6000 Series, and Radeon™ HD 5000 Series Graphics products have been moved to a legacy support model and no additional driver releases are planned.
