Re: GTX260 PSU and Hear Concerns
lallous go with the 750w psu. I've got the thermaltake toughpower 700w and it runs everything on my system with no problem.
IMHO I think 550w is a little low tbh and you might encounter problems. I also have good airflow in the case and additional fans and it all runs very cool. My GTX260 gets into the 70's under load and that includes an overclocked Q6600.
Hope this helps.
