MSI Unveils RTX 50 Ready MPG GS Power Supply Units: Up to 1250W, ATX 3.1 & PCIe 5.1 Compliant, Supporting Power Excursions up to 235%

MSI is set to unveil its latest series of Power Supply Units (PSUs) designed for high-performance gaming rigs, known as the MEG GS lineup.

Introducing the MPG GS Series: Affordable Performance Meets Advanced Technology

In a recent announcement, MSI detailed its top-tier model, the MEG Ai1600T, which caters to the luxury market with an impressive power output of 1600 Watts and a premium price of $699. However, the brand recognizes the need for more budget-friendly options. Consequently, MSI is expanding its offerings to include the new MPG GS series.

This new series will showcase three distinct models: the A1250GS, A1000GS, and A850GS, denoting their respective wattage capacities of 1250W, 1000W, and 850W. These units are designed to meet the demands of the latest high-end computers leveraging cutting-edge GPUs and CPUs.

A significant aspect of the MPG GS series is its adherence to the latest PCI-SEG standards, including ATX 3.1 and PCIe 5.1 compliance. This ensures enhanced safety and compatibility when integrating these PSUs into your system. All three models have also achieved certifications from Cybenetics ATX 3.1 and PPLP. INFO ATX 3, allowing them to handle power excursions of up to an extraordinary 235%.The calculations for sustained power capacities are as follows:

1250W x 2.35 = 2937.5W
1000W x 2.35 = 2350.0W
850W x 2.35 = 1997.5W

With the demands of modern graphics cards such as the RTX 40 and RTX 50 series, power spikes can occasionally exceed the nominal ratings. Using PSUs unsuitable for these power demands can result in system failures, including unexpected reboots. MSI’s MPG GS series is engineered to avoid such issues, ensuring reliability during even the most demanding tasks.

Moreover, the MPG GS series is equipped with PCIe 5.1 capability, featuring the latest 12V-2×6 power connectors that address common pitfalls associated with earlier 12VHPWR cable designs. Each unit is rated at 80 PLUS GOLD, guaranteeing enhanced efficiency, and incorporates a Semi-Digital (PFC+LLC) topology, built with 100% server-grade capacitors rated for operations up to 105°C. Details regarding pricing and availability remain forthcoming, but MSI anticipates a market launch in the near future.
