Corsair RM1000X Shift 1000W 80 Plus Gold ATX3.1 PSU

Overview

The CORSAIR RM1000x SHIFT series redefines the standard for PC power supply units by introducing a revolutionary side-mounted modular interface. By relocating the cable connections to the side face of the unit, this design significantly simplifies cable management, allowing for cleaner builds and easier access to your modular cables. This shift in layout ensures that your internal airflow remains unobstructed, providing a more efficient thermal environment for your high-performance components.

Engineered for the demands of modern computing, the RM1000x SHIFT is fully ATX 3.1 and PCIe 5.1 certified. It includes a dedicated 12V-2×6 GPU cable, making it the ideal power solution for the latest NVIDIA GeForce RTX 40-series graphics cards. With 80 PLUS Gold certification, you are guaranteed up to 90% power efficiency, translating to lower energy consumption, reduced heat output, and whisper-quiet operation under various load conditions.

Connectivity, Cooling & Power

The unit features a high-performance 140mm fan utilizing Fluid Dynamic Bearing (FDB) technology, which balances cooling effectiveness with longevity. The Zero RPM mode ensures the fan stays off entirely when the system is under light loads, creating a silent environment. For connectivity, the included Type 5 micro-fit cables are flat and flexible, simplifying the build process. Ensure your PC case is at least 210mm wide to accommodate the side-mounted cable profile comfortably.

Compu-Fi Expert Opinion

The RM1000x SHIFT is a game-changer for anyone tired of the cable clutter typical of traditional rear-facing PSUs. We highly recommend this for users building in cases with side-cable support, as it transforms the build process from a chore into a seamless experience. Pair this with a high-airflow chassis to maximize the benefits of the 140mm fan, and rest easy knowing your components are protected by a comprehensive 10-year warranty.
