WebBy Ohm's Law (V=I*R) that means that current = 50V/900 ohms= 55mA. Since Power= Current x Voltage, Power in this case is 0.055A x 50V=2.77 Watts. A 5-watt wirewound resistor should work OK, but it will get HOT, so mount it in a place where it can obtain airflow convection cooling (or use a chassis bolt-down resistor).
