Overview

The MSI MAG A1000GL PCIE5 is a 1000W 80PLUS GOLD certified power supply unit that supports the latest ATX 3.1 and PCIe 5.1 standards. Its fully modular cable design keeps your build tidy and improves airflow. It comes with a 7-year warranty for long-term peace of mind. This unit is sold on Amazon.co.jp by seller e-zoa (ASIN: B0D1DY97PK, model: MAG GL).

Key Features

  • ATX 3.1 / PCIe 5.1 Ready: Equipped with a native 12VHPWR connector for GeForce RTX 40-series and future GPUs. Enhanced transient response ensures stability under sudden load spikes.
  • 80PLUS GOLD Efficiency: Over 90% efficiency at 230V input, reducing heat and electricity costs.
  • Fully Modular Cabling: Connect only the cables you need for a clean build. Flat cables make routing easy even in tight spaces.
  • 135mm Silent Fan: Semi-fanless mode stops the fan under low load for near-silent operation. The fan ramps up smoothly under heavy load.
  • 7-Year Warranty: MSI backs this unit with a generous warranty period, reflecting its build quality.

Compatibility Guide

  • Form Factor: Standard ATX (150mm x 140mm x 86mm). Fits most mid-tower and full-tower cases. Not compatible with SFX or small form factor cases. Always check your case's PSU clearance before purchase.
  • Connectors: 1x ATX24-pin, 2x EPS12V 8-pin (CPU), 1x PCIe 5.1 12VHPWR, 4x PCIe 6+2-pin, 8x SATA, 4x peripheral 4-pin. Ample for high-end builds.
  • Motherboard Compatibility: Works with ATX, Micro-ATX, and Mini-ITX boards. Dual EPS12V cables support power-hungry CPUs like Core i9 or Ryzen 9.
  • GPU Compatibility: The native 12VHPWR connector eliminates the need for adapters with RTX 4070 and above. Also supports older GPUs via standard PCIe cables.

Ideal Builds

  • High-End Gaming PC: Pair with a Core i7/Ryzen 7 and RTX 4070 Ti Super or higher for headroom and overclocking stability.
  • Creator Workstation: Reliable power for long rendering sessions. High efficiency keeps thermals in check.
  • Future-Proof System: ATX 3.1 support ensures compatibility with next-gen components. The 7-year warranty makes it a long-term investment.

Upgrade Considerations

  • Bottleneck: 1000W is ample for single-GPU systems. For dual-GPU or extreme overclocking, consider 1200W+.
  • Over-Spec for Mid-Range: If you're building a mid-range PC (e.g., RTX 4060 + Core i5), a 650-750W unit is sufficient. This PSU is overkill but future-proof.
  • Case Size: Not compatible with small form factor cases. Verify your case supports ATX PSUs.
  • Cable Length: Included cables are long enough for full-tower cases, but if you plan extensive back-routing in a very large case, extensions may be needed.
