So, Im upgrading my GPU. Here are my current specs: RX 550, I7-3770, 4x4gb sticks of RAM, 500 gb hdd, 128 gb ssd, ATX MOBO. My PSU Wattage is 320 and I have been using this build for around 4.5 years. The GPU i want to buy is the GTX 1650. I found online that this GPU only consumes 25 watts more than the RX 550. Do I need to upgrade my PSU? Also PSU calculators are very confusing and each one i tried showed different Wattage requirements.
