A braking system for a motor vehicle comprises a first and second electrically controllable pressure source for providing a brake pressure for actuating the wheel brakes. An electrically controllable pressure modulation device sets brake pressures that are individual to each of the wheel brakes, said device having electrically actuatable inlet valves and outlet valves for each wheel brake. The second pressure source comprises a motor-pump unit and at least one low-pressure accumulator. The low-pressure accumulator is connected to an output connection of at least one outlet valve. A first and a second energy supply unit for the braking system are independent from one another. The first energy supply unit supplies the first pressure source with energy. The second energy supply unit supplies the second pressure source with energy. The pressure modulation device is supplied with energy by the first energy supply unit and by the second energy supply unit.
