I'd guess the specific items you just listed total 40 to 60 watts?
But I have absolutely no idea if that 220 watts figure you got from Nvidia is accurate during actual use. Or laughable.
Nor do I know how much a "65w ryzen" processor can draw under certain conditions.
Could well be 400 watts is the most it could possibly draw, but someone will always tell you about "headroom" and "in case you ever upgrade" and "err on the side of caution" and "it's aging" and so you end up with an 850 watt PSU.
The 3000 series cards can have high power spikes that may not be properly handled by your psu.
If you already own the 550w unit, you could try it.
But, be prepared to invest in a much stronger quality unit for the long term.
