MSI MAG A1000GL PCIE5 1000W 80+ Gold ATX 3.1 Fully Modular Power Supply
Unleash unwavering electrical stability for demanding GeForce RTX 40 and 50 series flagship rigs with the MSI MAG A1000GL PCIE5. Engineered to full Intel ATX 3.1 and PCIe 5.1 standards, it features a native 12V-2x6 600W connector with an innovative dual-color yellow connector head for visual insertion safety, high-efficiency 80 PLUS® Gold certification, full-bridge LLC DC-to-DC topology, and a whisper-quiet 120mm Fluid Dynamic Bearing fan.
Flagship RTX 4090 / 5090 Tier Gaming
Delivers full compliance with 200% power excursion requirements under Intel ATX 3.1 guidelines. Direct 600W 12V-2x6 delivery ensures rock-solid voltage without messy adapter splitters or contact resistance.
Heavy 24/7 Rendering & AI Workstations
Full-bridge LLC topology with DC-to-DC conversion guarantees strict voltage ripple suppression and continuous 90%+ electrical efficiency, reducing ambient thermal exhaust and monthly power consumption.
Power Architecture & Thermal Highlights
Intel ATX 3.1 & Native PCIe 5.1 Architecture
Fully compliant with the official Intel ATX 3.1 power supply guide, providing reinforced power excursion tolerance and ultra-clean single +12V rail delivery for cutting-edge multi-core CPUs and heavy GPUs.
Dual-Color Foolproof 12V-2x6 (600W) Cable
Features MSI's proprietary dual-color yellow connector head. If you can still see any yellow exposed when plugging into your graphics card, the connector is not fully seated, eliminating dangerous contact resistance.
120mm Fluid Dynamic Bearing (FDB) Fan
