after a crap load of research, I found this card and people said i needed to upgrade my psu, cuz im SOL.... so the guy recomended this PSU so, will it fit in a n insiron 530 case? and work normaly w/ my pc?
Enough and work normally? Yes probably, but you have to tell us the specs of your whole system to say for sure..Or better go to antec.com and use their PSU calculator.
Will it fit? Dunno ! read the dimensions in the PSU specs and measure the space available in your case and see for yourself.
