the PSU is good enough for the job

hedgehoge might not do the job properly
and it is often loud

i really suggest swiftech's MCX462 if you have the bling bling

also you would probably want to get the temp under 50c before doing any overclocking

and voltage should be added to provide more stability
but this is a very dangerous task
do some research before you do anything
and dont come back and complain that your CPU died
because i gave you a warning that this is very dangerous
and can damage your CPU permanantly

do some research
and go to the CPU Database in http://www.overclockers.com for a start
it will give you an idea what settings and setup ppl are doing with their 2000+
