Might be making a AMd gaming rig, i tryed to configure a really high end intel but came to 1500 big ones , so im looking at making a not so high end AMD rig, using a phenom II x4 965 3.4ghz. going to use AMD radeon hd 6770 GPU. what wattage PSU should be adequit? because i would like to know so i can be safe and get 100 watts over what i needed as a minimum. i like a cheap gaming rig but i like long and effective life as well. not sur ewhat current price is,as i havent found all the parts yet (as you can tell by me asking what PSU to use) any help would be great.
