Thanks for the advice, but I'm actually trying to not upgrade my PSU if possible, I just wanted to see if what I had could run a 6400+ (i know its a 125W, 90nm CPU and my current one is a 65W, 65nm - so I assumed there would be a jump in power demand and I really don't wanna fry my system) and if it can run one then if its possible to get another 8800gt in SLI along with the 6400+ or would that be overkill on my PSU.
I'm aware that it isn't the best PSU but it was cheap, looked great, and was SLI ready so I though it was a good purchase at the time. Sorry if my questions are confusing I'm not very good yet with PSU stuff, this was my first build so I'm new to this.
It will probably work, but will shorten your psu's life since their effeciency sucks...like mine. Get the psu first then 88gt or other way around .
edit: don't get the 6400+ it's a heat monster, rather get the 5000+ black edition
