In some implementations, a system controller of a computing device can be configured to receive a power-on signal and prevent the computing device from providing power to components of the computing device. In some implementations, upon receiving a power-on signal, the system controller can retrieve fault data from a power supply unit. The fault data can be analyzed to determine whether the power supply unit detected an unrecoverable failure. When an unrecoverable failure is detected, the system controller can prevent the power supply unit from providing power to other components of the computing device. In some implementations, an unrecoverable failure can be detected when the fault data indicates that an overcurrent, an overvoltage, or an over-temperature fault has occurred.

1. A method comprising: receiving, at a system controller of a computing device, a signal to power on the computing device;obtaining, by the system controller, power supply fault data from a power supply of the computing device;determining, by the system controller, that the power supply detected an unrecoverable fault based on the fault data; andpreventing the power supply from powering on the computing device. 2. The method of claim 1, wherein the system controller receives the signal from a power button configured on the computing device. 3. The method of claim 1, wherein the system controller receives the signal from a network interface controller, the signal including a command to power on the computing device. 4. The method of claim 1, wherein the system controller is a baseboard management controller. 5. The method of claim 1, wherein the unrecoverable fault is an overcurrent fault. 6. The method of claim 1, wherein the unrecoverable fault is an overvoltage fault. 7. The method of claim 1, wherein the unrecoverable fault is an overtemperature fault. 8. A non-transitory computer-readable medium including one or more sequences of instructions which, when executed by a system controller, causes: receiving, at the system controller of a computing device, a signal to power on the computing device;obtaining, by the system controller, power supply fault data from a power supply of the computing device;determining, by the system controller, that the power supply detected an unrecoverable fault based on the fault data; andpreventing the power supply from powering on the computing device. 9. The non-transitory computer-readable medium of claim 8, wherein the system controller receives the signal from a power button configured on the computing device. 10. The non-transitory computer-readable medium of claim 8, wherein the system controller receives the signal from a network interface controller, the signal including a command to power on the computing device. 11. The non-transitory computer-readable medium of claim 8, wherein the system controller is a baseboard management controller. 12. The non-transitory computer-readable medium of claim 8, wherein the unrecoverable fault is an overcurrent fault. 13. The non-transitory computer-readable medium of claim 8, wherein the unrecoverable fault is an overvoltage fault. 14. The non-transitory computer-readable medium of claim 8, wherein the unrecoverable fault is an overtemperature fault. 15. A system comprising: a power supply;one or more processors;a system controller; anda non-transitory computer-readable medium including one or more sequences of instructions which, when executed by the system controller, causes: receiving, at the system controller of the system, a signal to power on the system, where the one or more processors are powered down when the signal is received;obtaining, by the system controller, power supply fault data from the power supply of the system;determining, by the system controller, that the power supply detected an unrecoverable fault based on the fault data; andpreventing the power supply from powering on the system. 16. The system of claim 15, wherein the system controller receives the signal from a power button configured on the computing device. 17. The system of claim 15, wherein the system controller receives the signal from a network interface controller, the signal including a command to power on the computing device. 18. The system of claim 15, wherein the system controller is a baseboard management controller. 19. The system of claim 15, wherein the unrecoverable fault is an overcurrent fault. 20. The system of claim 15, wherein the unrecoverable fault is an overvoltage fault. 21. The system of claim 15, wherein the unrecoverable fault is an overtemperature fault.
