MSI MPG A1000G 1000W 80 + Gold Fully Modular ATX 3.0 Power Supply

The MSI MPG A1000G is a 1000W fully modular ATX 3.0 power supply designed for high-performance gaming builds, including systems powered by NVIDIA GeForce RTX 40 Series graphics cards. Its fully modular cable system — featuring flat cables throughout — allows you to connect only the cables your build requires, reducing clutter inside the chassis and improving airflow. Compliant with the Intel ATX 3.0 Power Supply Design Guide and PCIe 5.0, the MPG A1000G includes a native 16-pin PCIe 5.0 connector capable of delivering up to 600W to compatible graphics cards. The unit is rated to handle power excursions of up to 2000W — that is, 200% of its rated capacity — for transient durations of up to 100 microseconds, ensuring stability during GPU load spikes. Efficiency is certified at 80 Plus Gold, with the unit achieving up to 90% efficiency under typical loads. This translates into lower heat generation, reduced electricity consumption, and a quieter operating environment. Cooling is handled by a 135 mm fluid dynamic bearing fan, which is known for smooth, consistent airflow and a longer operational lifespan compared to sleeve-bearing alternatives. The topology relies on LLC half-bridge design paired with a DC-to-DC module, which helps maintain tight voltage regulation across all rails. The MPG A1000G operates on a single-rail architecture and accepts a wide input voltage range of 100–240 VAC at 50–60 Hz, making it suitable for use across different regional power standards. Six layers of hardware protection are built in: over-current protection (OCP), over-voltage protection (OVP), over-power protection (OPP), over-temperature protection (OTP), short-circuit protection (SCP), and under-voltage protection (UVP).
