Abstract: An example redundant power supply system comprises a power supply input to receive power from a power supply; a buck-boost converter coupled to the power supply input; and a controller coupled to the buck-boost converter. The controller is to receive a power supply identification signal from the power supply. The controller is also to enable or disable the buck-boost converter based on the power supply identification signal.

Abstract: In example implementations, a computing device is provided. The computing device includes an expansion interface, a first device, a second device, and a processor communicatively coupled to the expansion interface. The expansion interface includes a plurality of slots. Two slots of the plurality of slots are controlled by a single reset signal. The first device is connected to a first slot of the two slots and has a feature that is compatible with the single reset signal. The second device is connected to a second slot of the two slots and does not have the feature compatible with the single reset signal. The process is to detect the first device connected to the first slot and the second device connected to the second slot and disable the feature by preventing the first slot and the second slot from receiving the single reset signal.

Abstract: In example implementations, an apparatus is provided. The apparatus includes a riser card body, a first interface, a first 2×8 slot on a surface of the riser card body, and a second 2×8 slot on a same side of the surface of the riser card body as the first 2×8 slot. The first interface includes a first set of fingers and a second set of fingers at an end of the riser card body to connect to a peripheral component interconnect e×press (PC1e) slot of a motherboard. The first 2×8 slot and the second 2×8 slot are positioned perpendicular to the PCIe slot of the motherboard.

Abstract: In an example, a card retainer may include a latch to removably engage with a free end of an expansion card. Further, a card retainer may include a pivot mount to attach the latch to a system board of a computing device. In some examples, the latch is movable about the pivot mount between an open position and a closed position. The latch may exert a bias force on the free end of the expansion card in order to retain the expansion card to the system board in a secure manner when the latch is disposed in the closed position.

Abstract: Example implementations relate to power supply controllers. In some examples, a controller can include instructions to: set a power threshold for a power supply coupled to a computing component when the computing component is operating in a first state, determine when the computing component is alternating from the first state to a second state, and allow the power supply to exceed the power threshold for a fixed period of time in response to the computing component alternating from the first state to the second state.

Abstract: In example implementations, an apparatus is provided. The apparatus includes an accelerometer, a plurality of fan blades, a coil magnet and a processor. The accelerometer is coupled to a motor to measure an amount of vibration. The plurality of fan blades is coupled to the motor. Each one of the plurality of fan blades comprises a magnet. The coil magnet is coupled to a fan housing that encloses the motor, the plurality of fan blades and the accelerometer. The processor is communicatively coupled to the motor, the accelerometer, and the coil magnet. The processor activates the coil magnet to control a balance of the plurality of fan blades in response to an amount of vibration measured by the accelerometer that exceeds a threshold.

Abstract: Examples described herein relate to a non-transitory machine-readable medium consistent with the disclosure. For instance, the non-transitory machine-readable medium may store instruction executable by a processing resource to transfer additional power through a power delivery cable, input the additional power to a component of a computing device, and sequence the additional power with a main power supply of the computing device.
