I have a EVGA Supernova Gold 650w PSU and it runs between 200w-300w depending if I game or not (examples are Witcher 3 and Destiny 2). Factoring in the 320 Watts Nvidia mentions for the graphics card my wattage would roughly be around 620 am I able to still use my PSU or do I need a new one? I don't Stream
PS: I can't wait to upgrade my Geforce GTX 770
