Question Do I need to upgrade my PSU?

[Gekyumakos]

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.

There are no good 320W units that I know of. Sounds like one that came with an OEM case. I'm guessing its garbage and needs to be replaced. More so if it's been used for years.

Is this system a prebuild, or a custom DIY build? If it is a prebuild, what is the make, and model of the system?

You cannot upgrade the PSU, in that system. It is proprietary.
