Corsair RM1000x SHIFT Fully Modular ATX Power Supply Review

Overview

The Corsair RM1000x SHIFT is a high-end, fully modular ATX power supply designed to meet the demands of modern gaming systems and high-performance computing setups. It boasts an 80 PLUS Gold certification, ensuring efficient power delivery with minimal waste. This review will delve into its features, performance, and overall value.

Performance

The RM1000x SHIFT is equipped with a robust 1000W power output, making it suitable for systems with high-end graphics cards and multiple hard drives. It supports the latest standards, including ATX 3.0 and PCIe 5.0, ensuring compatibility with the latest hardware.

Design and Build Quality

The power supply features a sleek black design with a compact form factor (6.3 x 5.91 x 3.39 inches). The fully modular design allows for easy cable management, reducing clutter inside the case. The side-mounted connectors are innovative but can be problematic if the case isn't designed to accommodate them, potentially causing interference with other components.

Cooling System

The RM1000x SHIFT employs a low-noise fan that operates silently under regular loads. The Zero RPM fan mode ensures complete silence during idle or low-power usage scenarios, making it ideal for those who prefer a quiet computing experience. However, some users have noted that the fan might not kick in until temperatures rise significantly, which could lead to overheating if the system is pushed hard without adequate cooling.

Compatibility

One of the potential downsides is the lack of a dedicated 12VHPW connector, which is becoming increasingly common with the latest graphics cards. This could be a deal-breaker for those planning to upgrade their graphics card soon.

Additionally, the lack of a dedicated 12VHPW connector and potential overheating issues need to be considered. For those who value high efficiency, robust power output, and a premium build quality, the RM1000x SHIFT is a solid choice. However, it is essential to weigh these factors against your specific needs before making a purchase.
