Review

The Corsair HX1500i 1500W Modular Power Supply stands out as a beacon of power and efficiency in the high-performance PC components market. With an advertised 1500-watt output and boasting an 80 Plus Platinum efficiency rating, it caters to the needs of those who demand reliability and power for demanding systems.

Technical Specifications

This PSU is designed for the latest PC standards, featuring compatibility with ATX 3.0 and PCIe 5.0. This ensures future-proofing for system builders looking to upgrade to the latest GPUs and motherboards. The model supports an impressive array of connectors, including 1 ATX, 3 EPS, 9 PCIe, 8 SATA, and 8 PATA, which are neatly implemented in its fully modular design, providing flexibility and convenience in cable management. Further emphasizing its focus on performance, the unit is equipped with a fluid dynamic bearing fan which ensures efficient cooling while minimizing noise.

Design and Build Quality

The design of the HX1500i incorporates Corsair’s signature look with sleek black aesthetics. Despite its robust capabilities, the PSU maintains a relatively compact build with a depth of 200 mm, slightly large but understandable given its power output and the comprehensive array of components it houses. TechPowerUp notes the modular panel's complete occupation by connectors, a necessity for the extensive cabling requirements.

Performance and Reliability

The Corsair HX1500i utilizes a modern design with digital controllers handling most circuits, supplemented by components from reputable providers such as Chemi-Con and Rubycon for capacitors, and FETs from Vishay, ensuring top-tier build quality. A primary semi-digital architecture is evident, which includes interleaved PFC, full-bridge, and LLC converters, reinforced by synchronous rectification and DC-DC converters on the secondary side. Notably, the modular design minimizes ripple, a feature enhanced by the lack of in-cable capacitors, thus delivering smooth power to all components.

Usability and Software Support

A compelling aspect of the HX1500i is its integration with Corsair's iCUE software, enabling users to monitor the PSU’s output, efficiency, and fan speed in real-time, as well as switch between single-rail and multi-rail modes according to their needs. This suits users who prefer customizing their power delivery and monitoring to match their specific configuration demands.

Conclusion

The Corsair HX1500i 1500W Modular Power Supply is an excellent choice for high-end system builders and enthusiasts. Its blend of high power capacity, efficiency, and compatibility with the latest standards ensures robust performance, making it a future-proof investment in PC builds. Moreover, the meticulous component selection and thoughtful design elements such as the fluid dynamic bearing fan and modular cables underscore Corsair's commitment to quality, reliability, and user customization. As LDLC.com users have vouched, the power cables deliver quality and versatility, further endorsing the HX1500i’s standing as a go-to solution for power-hungry setups.
