CORSAIR RM1200x SHIFT Fully Modular ATX Power Supply - 80 PLUS Gold - ATX 3.1 - vs MSI MAG A1000GLS PCIE5 Power Supply Unit

Price Comparison

When it comes to price, the CORSAIR RM1200x SHIFT is significantly more expensive than the MSI MAG A1000GLS, retailing at £174.98 compared to £104.99. This represents a difference of £70. The higher price of the CORSAIR model reflects its advanced features and capabilities. The MSI unit, while more budget-friendly, offers essential performance at a lower cost, making it an attractive option for those with basic needs or limited budgets.

Efficiency Ratings

Both power supplies boast 80 PLUS Gold certification, indicating that they are capable of providing up to 90% efficiency. This means they are well-suited for powering high-demand hardware, such as modern GPUs and CPUs. The efficiency rating is crucial for users looking to reduce energy consumption and operating costs. While both products excel in this area, the CORSAIR's higher price might suggest additional benefits in terms of reliability and longevity, which could justify the cost for some users.

Design and Build Quality

In terms of design, the CORSAIR RM1200x SHIFT features innovative easy-access connection positioning, allowing for simpler cable management. It is equipped with fully modular micro-fit PSU connectors, which means only the necessary cables need to be connected, helping to maintain a clean build. The MSI MAG A1000GLS, on the other hand, has a compact design that measures 150 mm in length and width, making it easy to fit in various PC cases. Both units utilise high-quality fans; the CORSAIR has a 140 mm fluid dynamic bearing fan, while the MSI features a 135 mm fluid-dynamic bearing fan, both designed to ensure low noise operation.

Performance Under Load

The CORSAIR RM1200x SHIFT is designed to support high-performance systems, compliant with the ATX 3.1 power standard and capable of handling PCIe Gen 5.1. This makes it an excellent choice for users who plan to run the latest hardware and require stable power delivery, especially during peak loads. The MSI MAG A1000GLS also supports PCIe 5.1 GPUs with its native 12V-2x6 connectors, delivering up to 600W of power. While both units perform admirably under load, the CORSAIR's higher wattage capacity at 1200W allows for more headroom in demanding setups.

Cooling Solutions

Effective cooling is essential for the longevity and efficiency of a power supply. The CORSAIR RM1200x SHIFT utilises a specially calculated fan curve for high performance and low noise, ensuring that it operates quietly even under load. On the other hand, the MSI MAG A1000GLS also emphasises low-noise operation, maintaining sound levels akin to a peaceful night. Its cooling system is designed to enhance durability, which is important for users who value a quiet environment. Both units offer robust cooling solutions, but the CORSAIR may have a slight edge in performance due to its larger fan size.

Reliability and Durability

Reliability is a critical factor when choosing a power supply. The CORSAIR RM1200x SHIFT features 100% 105°C-rated Japanese electrolytic capacitors, which are known for their high-quality performance and long-term reliability. This ensures unwavering power delivery, even under demanding conditions. The MSI MAG A1000GLS also boasts a durable design with an LLC half-bridge and various protection features, such as over current protection (OCP) and over voltage protection (OVP). While both power supplies offer solid reliability, the premium components in the CORSAIR model may lead to a longer lifespan.

User Experience and Installation

User experience is an important aspect of any PC component. The CORSAIR RM1200x SHIFT’s innovative connection positioning makes installation easier and enhances cable management, which is appreciated by builders who prioritise aesthetics. The fully modular design allows users to connect only the cables they need, reducing clutter. The MSI MAG A1000GLS, while compact and straightforward, may not offer the same level of cable management convenience. However, its smaller size can help in tight builds, allowing for better overall airflow.

Which should you buy?

Choosing between the CORSAIR RM1200x SHIFT and the MSI MAG A1000GLS ultimately depends on your specific needs and budget. If you require a high-capacity power supply with advanced features, superior reliability, and exceptional cable management, the CORSAIR RM1200x SHIFT is worth the investment at £174.98. However, if you're looking for a cost-effective solution that still offers solid performance and efficiency, the MSI MAG A1000GLS at £104.99 provides excellent value for money. Consider your system requirements and budget carefully before making a decision.
