CX-M CX450M enough for Ryzen 3200g and Rx570 8b?
Yeah, it's enough
RX 570 uses up to around 180-200 watts on 12v, 3200g goes to maybe 60-80w , the rest of your system won't use over 25-50w.
So you need around 300-350w on 12v.
Manufacturers recommend higher wattage power supplies because a lot of power supplies from no-name manufacturers lie about their capabilities and don't actually supply the advertised number of watts, or that number of watts is split between the three main voltages a power supply produces : 3.3v , 5v and 12v.
So for example, you could have a psu say it can do 450 watts, but 100 watts is reserved on 3.3v, 100 watts is reserved on 5v, and only the rest of 250 watts is usable on 12v ... so such psu wouldn't work with your computer that needs 300+ watts at peak for your processor and video card, because you'll hit the 250 watts limit.
The psu you plan to get can output almost all those 450 watts on the 12v wires if needed, so you'll have plenty of margin.
