My pc has a 550 W PSU and on amazon it says the red dragon needs at least a 650W PSU. Pc partpicker on the other hand says it's compatible. Thoughts?

The PSU will work with the PC.

The manufacturer of the videocard assumes you have a terrible PSU, thus takes the 'better safe than sorry approach' of saying you need more wattage than actually needed. The Corsair RM550X is a good PSU, so will work.

 

Have you bought this PC entirely already, or did you just change the GPU?

That should be fine-- that's an extremely good 550W PSU, so it should handle a 5700 no problem. GN did a video where they ran all sorts of hardware off a 450W PSU-- no graphics card short of liquid cooled monstrosities draws more than 300W because it's near impossible to cool more than that in a standard 2-3 slot cooler.

 

PSU recommendations came from a time when high 12V power was a luxury item-- a 450W PSU from 15-20 years ago might only supply 350W on the 12V rail since older processors used mostly 5V power, thus they give plenty of headroom to not get in trouble.
