Hi im getting an AGP graphics card, (YES THEY STILL DO MAKE EM) and i have a 300w psu. Will 300 be enough to run the card, if not what would happen? Even if the manufacture reccomends 450w will they work on 300w? I really dont have the money to buy a psu. BUT if i do buy a new psu... is there a watt limit for the mobo it is a foxconn SIS661FX MR. I have a 300w in there now, what is the max? does anyone know?

Basically, if its not enough power, you'll get freezes and crashing... Gpu manmufactuers often over do theyre needed psu needs, so its quite possible it could work.
There is no limit to what a mobo can have for a psu, as the components only draw what they need. You'll just be less efficent with the power, as there is usually a higher efficiency loading point.
