Corsair RM1200x Shift Fully Modular ATX Power vs MSI MAG A750GLS PCIE5, Fully Modular Compact

Overview

The Corsair RM1200x Shift and the MSI MAG A750GLS are both high-quality power supplies designed for modern gaming and computing needs. However, they cater to different user requirements, particularly in terms of power capacity and pricing. The Corsair RM1200x Shift is priced at $194.99, while the MSI MAG A750GLS is significantly more budget-friendly at $89.99, making it about 54% cheaper.

Power Capacity

When it comes to power capacity, the Corsair RM1200x Shift stands out with its impressive 1200W rating, making it ideal for high-performance systems that demand substantial power, such as those with multiple GPUs or high-end CPUs. In contrast, the MSI MAG A750GLS offers 750W, which is still sufficient for most gaming setups but may limit expansion options for users looking to upgrade to more power-hungry components in the future.

Efficiency Ratings

Efficiency is a crucial factor in power supply performance, and both units boast an 80 PLUS Gold certification, indicating they can deliver up to 90% efficiency under load. This means that, regardless of the price difference, both power supplies are designed to minimize energy waste and heat generation. The Corsair RM1200x Shift is engineered for long-term reliability with its 105°C-rated capacitors, while the MSI MAG A750GLS also features durable design elements to ensure reliable output.

Modular Design

The Corsair RM1200x Shift features a fully modular design with micro-fit PSU connectors, allowing users to connect only the cables they need, which simplifies cable management and enhances airflow within the PC case. This innovative side interface design is particularly beneficial for building clean and organized systems. The MSI MAG A750GLS is also fully modular, which aids in cable management; however, it lacks the unique side cable interface, making it slightly less convenient in that aspect.

Noise Levels

Noise operation is another area where both power supplies aim to impress. The Corsair RM1200x Shift includes a Zero RPM fan mode, ensuring that the cooling fan operates silently under low to medium loads. This feature is ideal for users who prioritize a quiet computing environment. Similarly, the MSI MAG A750GLS is designed for low-noise operation, utilizing a 135 mm fluid-dynamic bearing (FDB) fan that maintains a sound level comparable to a peaceful night, making it a great choice for gamers and content creators alike.

Compatibility and Connectivity

The Corsair RM1200x Shift is Intel ATX 3.1 certified and supports PCIe Gen 5.1, making it an excellent choice for users looking to future-proof their systems. Its micro-fit connectors are specifically designed to support the latest graphics cards and components. The MSI MAG A750GLS is also ATX 3.1 and PCIe 5.1 ready, equipped with native 12V-2x6 connectors that can deliver up to 600W to support the latest GPUs. Both units ensure compatibility with modern hardware, although the Corsair offers greater overall power and flexibility.

Build Quality and Durability

Build quality is essential for ensuring longevity and reliability in power supplies. The Corsair RM1200x Shift features 100% Japanese 105°C-rated electrolytic capacitors, which contribute to exceptional power delivery and durability. The unit comes with a ten-year warranty, reflecting the brand's confidence in its longevity. The MSI MAG A750GLS also emphasizes durability, incorporating an LLC half-bridge with DC-to-DC converter and multiple protection features, backed by a ten-year warranty as well. Both units showcase premium build quality, but the Corsair's components may provide an edge in terms of longevity.

Pricing

The pricing of the Corsair RM1200x Shift at $194.99 positions it as a premium offering in the market, reflecting its higher power capacity and advanced features. Meanwhile, the MSI MAG A750GLS is priced at $89.99, attracting budget-conscious consumers while still delivering solid performance. The substantial price difference—about 117%—means that users must weigh their power needs against their budget when making a decision.

Which should you buy?

Choosing between the Corsair RM1200x Shift and the MSI MAG A750GLS ultimately depends on your specific needs and budget. If you require a high-capacity power supply with advanced features, the Corsair RM1200x Shift is the clear choice, albeit at a higher price point. However, if you're looking for a reliable, budget-friendly option for standard gaming or workstations, the MSI MAG A750GLS offers excellent value. Both power supplies excel in efficiency and noise operation, but their differences in power capacity and pricing will guide your decision.
