MSI MAG A1000GL 1000 Watt PCIe5 80 PLUS Gold Modular Power Supply

The MSI MAG A1000GL PCIe5 is a 1000W ATX 3.1 power supply designed for high-performance gaming and workstation builds. Built around a fully modular architecture, it ships with flat cables that simplify routing and improve airflow inside the chassis — a meaningful advantage when paired with dense, high-TDP hardware. At its core, the MAG A1000GL PCIe5 carries an 80 PLUS Gold certification, delivering up to 90% efficiency under typical load conditions. This keeps waste heat low and operating costs down compared to Bronze- or unrated units. The unit uses a half-bridge LLC topology combined with synchronous rectification and a DC-to-DC converter stage to maintain tight voltage regulation across the 12V, 5V, and 3.3V rails. A key differentiator is the native PCIe CEM 5.1 (16-pin) connector rated at up to 600W, making it a straightforward fit for NVIDIA GeForce RTX 40-series graphics cards without requiring adapters or cable rigs. Four additional PCIe 6+2 pin connectors are included for multi-GPU or legacy card compatibility. ATX 3.1 compliance means the unit can sustain up to 2× its rated wattage (2000W) in power excursion for transient spikes up to 100 µs — an important buffer when modern GPUs draw sudden, large current spikes during rendering workloads. Cooling is handled by a 135 mm fluid dynamic bearing fan, chosen for its lower friction, reduced noise, and longer operational lifespan compared to sleeve-bearing alternatives. Active PFC (Power Factor Correction) ensures a cleaner draw from the mains across the full 100–240V input range and 50–60 Hz frequency spectrum, making the unit globally compatible. Six independent protection circuits — Over Current (OCP), Over Voltage (OVP), Over Power (OPP), Over Temperature (OTP), Short Circuit (SCP), and Under Voltage (UVP) — monitor the system continuously to safeguard connected components. The MAG A1000GL PCIe5 is backed by a 7-year manufacturer warranty. **Verified Specifications:** - Rated Output: 1000W - Peak Power Excursion: 2000W (up to 200% for 100 µs) - Efficiency: 80 PLUS Gold (up to 90%) - ATX Standard: ATX 3.1 - Modular: Fully modular, flat cables - Fan: 135 mm, Fluid Dynamic Bearing - PFC: Active PFC - Input Voltage: 100–240V~ - Input Frequency: 50–60 Hz - Dimensions (D×W×H): 150 × 150 × 86 mm - Connectors: 1× ATX 24-pin, 2× EPS 4+4-pin, 1× PCIe 5.1 16-pin (600W), 4× PCIe 6+2-pin, 12× SATA 15-pin, 4× Molex 4-pin, 1× FDD 4-pin - Protection: OCP / OVP / OPP / OTP / SCP / UVP - Warranty: 7 Years
