Can you please suggest whether this PSU is appropriate?

I am building an mATX setup.

- MSI Ryzen B450M MORTAR MAX AM4 mATX Motherboard

- Ryzen 5 3600 Processor

- Screen is 1440p 144hz

And a graphics card which has a recommended PSU of 550W

I have already purchased the following PSU:

CORSAIR - TX550M Semi-Modular ATX PSU - 550 W. (gold rated)

I thought this was fine but everything I am reading on the internet offers conflicting advice, I am inclined to go with he advice of the GPU manufacturer (above) but I'm new to PC building and I've figured everything else out except for this PSU business.

Can anyone offer advice here? Do I need more wattage? I can return this PSU I bought already but would rather not go through the hassle if I can avoid it.

If I am able to get it, it will be a variant of one of the 3600's due for release.

Either

GIGABYTE GeForce RTX 3060 12 GB EAGLE

or

MSI GeForce RTX 3060 12 GB GAMING X Graphics Card

550w will be fine i just checked the specification for both and they are both 550w.

Thank you! I am getting the same results when I use a PSU calculator, there is quite a divide on the internet about PSU. The confusion for me is that everyone on blogs, youtube, etc seems to have a PSU at least 100w over the recommended for their setup
