A 500W@ 25A PSU is a extremly weak Power Supply :-/
For the 4830 something like a Corsair 400W / 32A will be plenty and will power everything with ease.
However, if you want more head room for future upgrads etc.. , thats fine,
Im just saying this is the min. you should be aiming for. You'll have a little headroom, but not much.
just keep in mind to get a good quality PSU.
Pay attention to the 12V rail most of all, and effeciency and you will be fine,.
And by good quality that doesnt mean 'most expenisive" Or biggest wattage.
