plz help me im waitingto buy the card now so a reply would help a lots
thanks for reading
Yep you're good power wise a HD 4830 requires 26A on the 12V rail.
400-500W psu will power the card provided it supplies the amperage and yours does.
Clean your case and components like heatsink,fans,etc.
Temps will drop.
thanks one more question is had a 8600gt and was working for half a week and then the screen turned off then i had a dead card so i put my 6800gt back in.do u think think the 8600gt overheated i got it 2nd hand on eBay.also is a 4830 hd good for gameing for cheap cost
Personally i would never buy a 2nd hand gpu unless i knew the person.
From the sounds of it you're on a budget,which is fine.
Honestly i would buy something new and current with a warranty.
Plenty of decent cards under $100 like 5570/5670/5770
GTS 250/GTS 450 http://www.tomshardware.com/reviews/best-graphics-card-...
