I recently upgraded my motherboard, GPU, RAM, and video card when I began to wonder about my Power Supply.
When, if ever, would one need to upgrade? It's a 850w XFX and has served me well these last few years. I've noticed a good number of computers use 550w, 600w, and 700wpower supplies in their rigs and though mine is discontinued Im not sure if a replacement is needed. Would I only need one if my computer demanded more than 850w? http://www.newegg.com/Product/Product.aspx?Item=N82E16817207001
