24V C Wire Adapter Help

Hey everybody,
I recently got a Honeywell Home thermostat and when I installed it, it kept flashing on and off. Turns out that the furnace couldn’t give it enough power on its own, so I just got a 24V Power Adapter that I will plug into an outlet near my furnace. I have single pipe steam heat, with no AC.

I have two questions: will connecting the two wires to the C terminal and the RH terminal, along with the W wire from the furnace to the thermostat, give it enough juice? The instructions on the adapter say to connect the wires to the C terminal and the RC terminal, which confused me since I don’t have cooling.
My second question is if I do connect the adapter wires to the C and RC, along connecting the RH and W wires from the furnace to the thermostat give me enough power, and is one option better than the other? Or am I completely off base? Thanks guys! I’m still learning haha
I can provide pictures if that is more helpful

Thanks Ed! There is currently a jumper connecting those two so I will remove that. Sounds simple enough, I will do just that.0
