MSI MAG A1000GL PCIE5 II alimentatore 1000 W 24-Pin ATX ATX nero

The MSI MAG A1000GL PCIE5 II is a 1000 W ATX power supply unit designed for gaming systems that require stable, high-current delivery. It meets ATX 3.1 readiness and includes a native dual-color PCIe CEM 5.1 connector to support modern GPUs. The unit is 80 PLUS Gold certified for improved energy efficiency and uses a 135 mm fluid dynamic bearing fan for balanced cooling and low noise.

Advantages

This modular power supply provides fully modular, flat cables to reduce clutter and simplify cable management, plus an included cable pack for storing unused leads. The half-bridge LLC with DC/DC converter topology delivers higher conversion efficiency and stable voltages under varying loads. The single-rail design supplies sufficient current to high-performance CPUs and GPUs, and built-in protection mechanisms (OVP, OCP, OPP, OTP, SCP, UVP) help ensure safe, reliable operation.

Suitable for

• High-performance gaming PCs with NVIDIA GeForce RTX 40 series graphics cards
• Custom desktop builds requiring ATX 3.1 compatibility and PCIe 5.1 GPU power
• Systems where efficient power usage and quieter cooling are priorities

How to use

Install the MSI MAG A1000GL PCIE5 II into a compatible ATX case following standard PSU mounting procedures. Connect the 24-pin ATX cable to the motherboard and attach the required modular PCIe and CPU power cables according to component power needs. Use only the cables required for the build to minimize clutter and route flat cables to improve airflow. Ensure the AC input matches 100–240 V and use a properly rated mains cable and surge protection if available.

Recommendations

For optimal performance, pair this PSU with modern GPUs that require PCIe 5.1/CEM connectors and keep unused modular cables stored in the included cable pack. Maintain regular dust cleaning of the 135 mm fan and ensure adequate case airflow to prolong component life.
