Power Supply McPower Face is an ATX-style desktop computer power supply designed for students, hobbyists and PC builders who want to better understand how power is used inside a computer. The system is designed to give standard desktop PC power rails while also displaying live telemetry of voltage, current, power draw, and efficiency, directly on a built-in screen. PSMcPF has several key technologies commonly found in modern power supplies, including AC-to-DC conversion, regulated +12 V, +5 V, and +3.3 V ATX output rails, modular DC output cabling, current and voltage sensing, microcontroller guided telemetry processing, and an LCD user interface. The system is designed around a 500 W operating range, 120 V AC input, active cooling control, all while having real time measurement updates at least once per second. The current system architecture separates the design into major blocks including the AC/DC inverter, 5 V standby supply, ATX rails, system monitoring, microcontroller, display, code, and enclosure/cooling design. The most notable accomplishment of this project is combining power conversion, monitoring, modular cabling, enclosure design, and live user-facing telemetry into one platform. The main challenges were safely working around high-voltage power circuitry, integrating several subsystems into a compact ATX-sized enclosure, and validating each block before full system integration. Future improvements could include further efficiency optimization, more advanced protection features, improved enclosure airflow and expanded telemetry or logging features.
