Power supply unit MSI MAG A1000GL PCIE5 WHITE 1000 W ATX 24-pin, 80 PLUS Gold, 135 mm fan

MSI MAG A1000GL PCIE5 WHITE is a 1000 W ATX power supply designed for desktop systems requiring high, stable power delivery. It features 80 PLUS Gold efficiency, a 135 mm fluid dynamic bearing fan, fully modular flat cables and native PCIe CEM 5.1 support to work with modern high-performance graphics cards and CPUs. The unit accepts 100–240 V AC input at 50/60 Hz and uses a standard 24-pin ATX motherboard connector; the white finish suits light-coloured system builds.

Advantages

The single-rail 1000 W design provides stable and concentrated power for demanding components, while ATX 3.1 readiness and a native dual-color PCIe CEM 5.1 connector enable compatibility with recent GPU generations. The fully modular layout with flat cables simplifies cable management and airflow. 80 PLUS Gold certification and Active PFC contribute to efficient operation, and multiple protection mechanisms (OVP/OCP/OPP/OTP/SCP/UVP) help ensure safe and reliable performance.

Suitable for

• High-performance gaming PCs with GeForce RTX 40/50 series graphics cards
• Workstations with demanding CPU and GPU loads
• Custom builds that require modular cables and a white aesthetic

How to use

Install the MSI MAG A1000GL into a compatible ATX case, secure it to the PSU mounting area and connect the 24-pin ATX cable to the motherboard. Use the modular PCIe and CPU power cables to attach power to the graphics card(s) and CPU according to the motherboard and GPU manufacturer guidelines. Ensure the AC mains cable is rated for your region and connect to a properly grounded outlet. Leave adequate ventilation around the PSU so the 135 mm fan can maintain optimal cooling.

Recommendations

For stable operation with high-end GPUs, verify combined system power draw against the 1000 W rating and allow headroom for power excursions. Use recommended PCIe CEM 5.1 connections for ATX 3.1 systems, keep modular cables tidy to preserve airflow, and place the PSU in a well-ventilated area. Regularly inspect connectors and cables for wear and ensure the system is connected to a surge-protected outlet.
