MSI MPG A1000GS (1000W) PCIE5 80 Plus Gold ATX 3.1 PSU

The MSI MPG A1000GS is a high-end 1000W ATX power supply, aimed at serious gaming and workstation configurations with modern GPUs. With an 80+ Gold certification and up to 90% efficiency, it is designed for stable operation under high load without excessive energy and heat losses. Support for ATX 3.0/3.1 and PCIe Gen 5.0/5.1 means you are fully prepared for the new generation of graphics cards. In a compact ATX body with a length of only 150 mm, the power supply is a convenient choice even for smaller cases.

What you get

With a real power output of 1000W and DC 3.3/5/±12 V output, you have sufficient resources for a top CPU + high-end GPU without worrying about stability. The two PCI-E 5.1 (16 pin) connectors at 600W each allow you to power modern graphics cards directly via the new 16-pin standard, without adapters or cable gymnastics. Thanks to the modular design, you attach only the necessary cables, improve airflow, and make cable management easier. The 135 mm FDB fan handles cooling with lower noise and a longer lifespan compared to standard fans. Active PFC helps provide more stable power and better compatibility with various electrical installations in the 100–240 VAC range.

• 1000W Power – sufficient for high-end configurations with a powerful GPU, multiple storage drives, and additional fans or liquid cooling.
• 80+ Gold certification and up to 90% efficiency – less energy loss, lower temperature, and quieter operation under load.
• ATX 3.0/3.1 and PCIe Gen 5.0/5.1 support – readiness for current and future graphics cards without the need for adapters.
• 2x PCI-E 5.1 (16 pin, 600W) + PCI-E (6+2 pin) – flexibility to power both new and previous generation GPUs.
• Modular design – remove unnecessary cables, improve airflow, and facilitate assembly and maintenance.
• 8x SATA and 4x PERIPHERAL (4 pin) – enough connectors for SSDs, HDDs, fans, and additional accessories.
• 135 mm FDB fan – a quieter and more durable cooling fan compared to standard Sleeve solutions.
• Compact dimensions 150 x 150 x 86 mm – easy fit in most ATX cases, including shorter chassis.
• 120-month warranty – long-term peace of mind for one of the most important components in your system.

Who it is suitable for

This power supply is suitable if you are planning or already have a powerful gaming or creative build with a high-end GPU and want to be prepared for PCIe 5.0/5.1 cards. It is ideal for systems with many drives and accessories, where stability and efficiency are critical. If you are building an ultra-budget machine or a mini-ITX build requiring an SFX format, this is not the most logical choice.

The combination of 1000W power, ATX 3.1 + PCIe 5.1 connectors, and 80+ Gold efficiency makes the MSI MPG A1000GS a reliable foundation for a serious PC that you will not be replacing soon.
