MSI MAG A1000GL 1000W 80+ Gold Fully Modular ATX 3.1 Power Supply

The MSI MAG A1000GL is a 1000W fully modular power supply built to the ATX 3.1 standard, designed for high-performance gaming and workstation builds. At its core, it carries an 80 PLUS Gold efficiency certification, achieving up to 90% efficiency to reduce wasted energy and lower heat output inside your chassis. A key highlight is the native PCIe CEM 5.1 connector — a dual-colour 16-pin cable rated at 600W — that connects directly to NVIDIA GeForce RTX 40-series graphics cards without adapters. The ATX 3.1 specification also allows the unit to handle power excursions of up to 2000W (200% of rated capacity) for brief transient loads of 100 microseconds, ensuring GPU power spikes do not cause instability. The fully modular design means every cable, including the 24-pin ATX and both EPS connectors, detaches completely. Only the cables your build needs go inside the case, and the included cable storage solution keeps unused cables tidy. Flat ribbon-style cables further simplify routing and leave more room for unobstructed airflow. Cooling is managed by a 135mm fluid dynamic bearing fan, a fan type chosen for its balance of quiet operation and long service life. Internally, an LLC half-bridge topology combined with synchronous rectification and a DC-to-DC converter module delivers stable output voltages across varying loads. Active Power Factor Correction (Active PFC) maintains a clean power draw from the wall across the full 100–240V universal input range at 50–60Hz. Six protection layers — Over Current (OCP), Over Voltage (OVP), Over Power (OPP), Over Temperature (OTP), Short Circuit (SCP), and Under Voltage (UVP) — monitor the system continuously. MSI backs the unit with a 7-year warranty.
