I want to ad another card and upgrade my 95w fx-6300 to a 125w fx-8320 with a 4ghz overclock.
At miminal load the numbers look fine but according to my estimates at peak load i will be at around 485 watts. This is the new 2016 model xfx psu with guaranteed true wattage. Would this be safe? I am not willing to switch out the psu as I just got it and its only $30 after rebate.
