IMHO, no. Looks like from the hardware in your signature that your still way lower then your rated watts and remember the rated isn't where you want to be running. I think pc parts picker has a area where you can enter all your hardware and they will suggest a wattage for a power supply, but its usually on the low side in my book, I would rather have it and never need it, then need it and not have it. NOW on the other part of that you will run a little cooler with a PSU only working half as hard to provide your system then one right at the edge of your limit. and since heat is the enemy.... I am running way more then I need, would rather run a PSU at 50% with less heat then a 600 watt running towards the upper end of its limits with all that heat. Also look forward a little and see if your done with your mods, is there going to be a liquid cooler in your future...(thats what I am deciding now) more fans? More Processor? A amd 8350 is typically over 30% more heat by design then the 95 watt 6300, and who knows whats next for them. Also how hard are you going to run yours? I will be happy with a rock solid 4.4-4.6, so define your goals and these people on here are the best for helping. advise and not to much BS.
