2070S graphics card 500W power supply is definitely not enough, even if it is enough, it is very tired. It is recommended to choose a power supply with higher power.

The RTX2070S consumes about 270W at full load. Even if the power consumption of the CPU is 90W (the CPU may be higher), the power consumption of other hardware is 20W, so the power consumption of the computer when it is fully loaded is 380W. It is healthy to use less than 60% electricity, and it is recommended to use more than 600W power supply.
