Hello. I currently finished my PC. On PCPartPicker, it shows my my total Wattage, which is 334 watts. Should I get an extra 100 watts so the Power Supply won't stress into putting all of the power into every component? Also, should I get more just to be safe? I am planning to get a 430 Watt Power Supply.
