CORSAIR RM1200x SHIFT Fully Modular ATX Power Supply - 80 PLUS Gold - ATX 3.1 - vs Corsair HX1000i Fully Modular Ultra-Low Noise ATX Power Supply - ATX 3.1 & PCIe

Introduction to the Corsair RM1200x SHIFT and Corsair HX1000i

The Corsair RM1200x SHIFT and Corsair HX1000i are both fully modular ATX power supplies that offer high performance and efficiency. Priced at £174.98 and £169.99 respectively, they cater to users seeking reliable power solutions for their systems. Each model comes with its own set of features designed to enhance user experience while ensuring optimal power delivery.

Design and Build Quality

Both power supplies exhibit robust build quality, but they differ in their design features. The RM1200x SHIFT stands out with its innovative easy-access connection position, allowing for simpler cable management. In contrast, the HX1000i also promotes clean builds with its fully modular cabling system, but lacks the side access feature of the RM1200x SHIFT. This unique aspect makes the RM1200x SHIFT potentially more user-friendly for builders who value neatness in their setups.

Cooling Performance

Cooling performance is crucial for power supply longevity, and both models utilise a 140mm Fluid Dynamic Bearing fan. However, the HX1000i offers a Zero RPM Fan Mode, which allows the fan to switch off entirely at low and medium loads, resulting in near-silent operation. The RM1200x SHIFT, while also prioritising low noise with a specially calculated fan curve, does not feature a similar silent mode. For users prioritising quiet operation, the HX1000i may have the edge.

Efficiency and Certification

Efficiency is a key factor in power supplies, and both products are Intel ATX 3.1 certified, supporting the PCIe Gen 5.1 platform. The RM1200x SHIFT is rated as 80 PLUS Gold, signifying high efficiency under typical loads. While the HX1000i does not specify its efficiency rating, being part of the same series implies it meets similar standards. Users can expect both models to resist transient power spikes effectively, ensuring stable performance during demanding tasks.

Cable Management

Cable management is simplified in both models, with fully modular cabling that allows users to connect only the necessary cables. The RM1200x SHIFT uses CORSAIR Type 5 Gen 1 micro-fit PSU connectors, which are designed to occupy less space and enhance airflow within the chassis. The HX1000i, while also fully modular, does not mention a similar space-saving design. For users focused on maximising airflow and reducing clutter, the RM1200x SHIFT may be the more appealing choice.

Software Integration

The HX1000i has a significant advantage with its powerful CORSAIR iCUE software integration. This feature lets users create custom fan curves, monitor power settings, and adjust overcurrent protection on-the-fly. The RM1200x SHIFT lacks such software capabilities, which may limit its functionality for advanced users who wish to fine-tune their power supply settings. The added convenience of iCUE could be a deciding factor for tech enthusiasts looking for deeper control over their system's performance.

Price Comparison

The pricing of both power supplies is competitive, with the RM1200x SHIFT at £174.98 and the HX1000i at £169.99. The slight difference in price may influence purchasing decisions, especially considering the features offered. While both models present excellent value for their respective capabilities, potential buyers may weigh the cost against specific features that align with their needs.

Which should you buy?

Choosing between the Corsair RM1200x SHIFT and Corsair HX1000i ultimately hinges on individual preferences and specific requirements. If easy cable management and innovative design are paramount, the RM1200x SHIFT is a strong contender. Conversely, if silent operation and advanced software integration are more critical, the HX1000i might be the better choice. Both power supplies offer excellent performance, but assessing their unique features will guide users in making the best decision for their systems.
