CORSAIR RM1200x SHIFT Fully Modular ATX Power Supply - 80 PLUS Gold - ATX 3.1 - vs Cooler Master MWE 750 Gold V2 Fully Modular PSU

Overview of the CORSAIR RM1200x SHIFT and Cooler Master MWE 750 Gold V2

The CORSAIR RM1200x SHIFT and Cooler Master MWE 750 Gold V2 are both fully modular power supplies, but they cater to different segments of the market. The RM1200x SHIFT is priced at £174.98, while the MWE 750 Gold V2 is more budget-friendly at £141.41. This price difference reflects their respective target audiences and specifications, with the RM1200x SHIFT offering higher wattage and advanced features suitable for high-end systems.

Power Output Comparison

The CORSAIR RM1200x SHIFT delivers an impressive 1200 watts, making it ideal for users with high energy demands, such as gamers with multiple graphics cards or those running powerful workstations. In contrast, the Cooler Master MWE 750 Gold V2 provides 750 watts, which is sufficient for most mid-range gaming systems and general use. This significant difference in wattage indicates that the RM1200x SHIFT is designed for more intensive applications, while the MWE 750 Gold V2 targets more standard setups.

Efficiency Ratings

Both power supplies boast an 80 PLUS Gold efficiency rating, but the specifics of their efficiency under typical loading conditions differ. The MWE 750 Gold V2 claims a 90% efficiency, which is excellent for reducing energy costs and heat generation. While the CORSAIR model is also certified as 80 PLUS Gold, it does not specify an efficiency percentage, leaving its comparative efficiency somewhat ambiguous. Nevertheless, both units are designed to minimise energy wastage, but the MWE 750 Gold V2 provides a clearer efficiency claim.

Cable Management Features

Cable management is a crucial aspect of any power supply, and both products excel in this area. The CORSAIR RM1200x SHIFT features innovative easy-access connection positions, allowing for simpler and cleaner cable management. Its fully modular micro-fit connectors also mean users can connect only the cables they need, reducing clutter. On the other hand, the Cooler Master MWE 750 Gold V2 offers fully modular flat black cabling, enhancing aesthetics and airflow within the case. While both models provide robust cable management options, the RM1200x SHIFT’s design may appeal more to users prioritising ease of access.

Cooling Solutions

The cooling mechanisms of each power supply are tailored to their performance needs. The CORSAIR RM1200x SHIFT employs a 140mm fluid dynamic bearing fan, engineered for high performance and low noise, ensuring reliability during intense usage. The MWE 750 Gold V2 utilises a 120mm hydro-dynamic bearing fan that responds to temperature changes, optimising power efficiency and noise levels during low-demand periods. While both fans aim to maintain low noise, the larger fan in the RM1200x SHIFT may offer better cooling for high-performance setups.

Temperature Resilience

Temperature resilience is another area where these two power supplies differ significantly. The Cooler Master MWE 750 Gold V2 is designed to operate at a higher temperature threshold of 50°C, which is beneficial for overclocking and running demanding applications. In comparison, the thermal specifications for the CORSAIR RM1200x SHIFT do not explicitly mention its temperature rating, potentially limiting its appeal for users who intend to push their systems to the limits. This makes the MWE 750 Gold V2 a more attractive option for those looking to overclock or utilise powerful graphics cards.

Brand Reputation and Support

Both Corsair and Cooler Master have established strong reputations in the gaming and PC hardware markets, known for their quality products and customer support. Corsair is often lauded for its premium components and reliability, while Cooler Master is recognised for balancing performance and affordability. Investing in either brand typically comes with the reassurance of good customer service and warranty support, making both options viable for consumers.

Which should you buy?

Deciding between the CORSAIR RM1200x SHIFT and the Cooler Master MWE 750 Gold V2 boils down to individual needs and system requirements. If you're building a high-end system that demands a robust power supply capable of supporting multiple components, the RM1200x SHIFT’s 1200 watts and advanced features justify its higher price of £174.98. Conversely, if you're looking for a reliable and efficient power supply for a mid-range setup, the MWE 750 Gold V2 at £141.41 offers excellent value with its 750 watts and high-temperature resilience. Ultimately, your choice should depend on your specific requirements and budget constraints.
