CORSAIR RM1000x SHIFT vs Corsair HX1000i Fully Modular Ultra-Low Noise ATX Power Supply - ATX 3.1 & PCIe

Overview of the Power Supplies

In this comparison, we will examine the CORSAIR RM1000x SHIFT and the Corsair HX1000i Fully Modular Ultra-Low Noise ATX Power Supply. Both power supplies are designed for high-performance systems, but they cater to slightly different needs and preferences. The RM1000x SHIFT is priced at £164.99, while the HX1000i costs £169.99. This article will delve into their features, performance, and usability to help you decide which power supply is right for your build.

Design and Build Quality

When it comes to design, the RM1000x SHIFT offers an innovative side connection position that simplifies cable management. This design choice makes it easier to access the modular connections, enhancing overall build aesthetics. The HX1000i, on the other hand, is fully modular like its counterpart, allowing you to connect only the necessary cables for a clean setup. Both power supplies feature a 140mm Fluid Dynamic Bearing fan, but the HX1000i’s additional Zero RPM Fan Mode allows for completely silent operation at low and medium loads, which may appeal to users prioritising noise levels.

Modular Capabilities

Each power supply boasts fully modular connectors, but the RM1000x SHIFT includes CORSAIR Type-5 PSU cables that are smaller, enabling better routing and tidiness. This feature is particularly beneficial for those who appreciate an uncluttered interior. Conversely, the HX1000i also offers fully modular cabling, making it straightforward to connect only the cables your system requires. While both options excel in modularity, the RM1000x SHIFT's design specifically caters to clean cable management with its debossed PVC cable kit.

Cooling Efficiency

Cooling is critical for maintaining system stability, especially under heavy loads. The RM1000x SHIFT utilises a specially calculated fan curve for high performance and low noise, ensuring reliable operation. In comparison, the HX1000i’s 140mm Fluid Dynamic Bearing fan is engineered for quiet performance, complemented by the Zero RPM Fan Mode that turns off the fan entirely under light loads. For users focused on maintaining an ultra-quiet system, the HX1000i may be the more attractive option due to its near-silent operation capability.

Compatibility and Standards

The RM1000x SHIFT is designed to cater to modern graphics cards thanks to its native 12V-2x6 GPU cable, which can easily power the latest NVIDIA GeForce RTX 50 Series. This compatibility makes it a suitable choice for gamers and professionals who require robust power for high-end components. The HX1000i, however, is Intel ATX 3.1 certified, supporting the PCIe Gen 5.1 platform and providing resilience against transient power spikes. Users looking to future-proof their builds may find the HX1000i’s compliance with the latest standards advantageous.

Software Features

The HX1000i comes equipped with powerful CORSAIR iCUE software, allowing users to create custom fan curves, monitor power settings, and toggle between single to multi-rail overcurrent protection (OCP) on-the-fly. This software integration offers a level of control that the RM1000x SHIFT does not provide. For tech enthusiasts who want to fine-tune their power supply settings and monitor performance metrics, the HX1000i presents a clear advantage.

Price Consideration

Pricing plays a significant role in any purchase decision, and both power supplies are closely priced, with the RM1000x SHIFT at £164.99 and the HX1000i at £169.99. The slight difference of £5 may be negligible for some, but it could influence budget-conscious buyers. While the RM1000x SHIFT offers exceptional features for its price, the HX1000i provides added functionalities and future-proofing that may justify the higher cost for those looking for long-term investment.

User Experience and Installation

Both power supplies are designed for ease of installation, but the RM1000x SHIFT’s innovative connection position could make it simpler for users to manage cables during setup. The fully modular design of both units eliminates the need for unused cables, contributing to a more straightforward installation process. However, the HX1000i’s software capabilities may enhance user experience post-installation, especially for those who enjoy customising their power settings and monitoring system performance.

Which should you buy?

Choosing between the CORSAIR RM1000x SHIFT and the Corsair HX1000i ultimately depends on your specific needs and preferences. If you prioritise innovative cable management, a lower price point, and compatibility with modern GPUs, the RM1000x SHIFT is an excellent choice. However, if you seek advanced features such as iCUE software integration, certified compliance with the latest power standards, and the benefit of an ultra-quiet operation, the HX1000i is worth the additional £5. Both power supplies are reliable options, but your choice should align with your particular use case and future-proofing desires.
