A technician is selecting a power supply for a new computer. There will be a large number of connected devices that must be powered by USB. Which of the following specifications should the technician prioritize?
USB devices rely on 5V output from the power supply, so the amperage rating at 5V is critical to ensure enough power is available for multiple USB devices. A modular connector count affects cable management, while a 20+4 power connector is standard for motherboard connections. Energy efficiency impacts overall power usage but is not specific to the needs of USB devices. This matches CompTIA A+ Core 1 objectives regarding power supply selection based on device requirements.
