The Corsair RM1000x SHIFT is a high-performance 1000W fully modular ATX power supply designed for modern gaming PCs, high-end workstations, and systems using demanding graphics cards. With ATX 3.1 certification, PCIe 5.1 support, a native 12V-2x6 GPU power cable, and Cybenetics Gold efficiency, it delivers stable and efficient power for current and next-generation PC hardware.
Its side-mounted modular connections make cable installation and management more accessible, while the compact Type-5 connectors help reduce cable clutter inside the case. A 140mm Fluid Dynamic Bearing fan, Zero RPM Mode, and manual fan speed control provide flexible cooling with low noise during lighter workloads and additional airflow when the system is under heavy load.
Description
The Corsair RM1000x SHIFT 1000W PSU combines high power output, modern connectivity, efficient operation, and flexible cooling in a fully modular design. It is well suited to gaming PCs equipped with powerful GPUs, including modern NVIDIA GeForce RTX 50 Series graphics cards, while the native 12V-2x6 cable provides a direct power connection for compatible graphics cards.
The ATX 3.1 and PCIe 5.1 compliant design helps prepare your system for newer hardware and demanding power requirements. Inside, the PSU uses a robust resonant LLC topology with DC-DC conversion and 105 degree C-rated Japanese industrial-grade electrolytic capacitors for reliable operation under sustained loads.
The side-mounted Type-5 connectors are a key part of the RMx SHIFT design. They position the modular connections where they are easier to reach, which can make installing and routing cables more convenient. The PSU requires approximately 30mm of clearance between the power supply and the case side panel for this connection layout.
Features
Corsair RM1000x SHIFT 1000W Power Supply
With 1000 watts of available power, the RM1000x SHIFT provides plenty of capacity for powerful desktop configurations. Its fully modular design means only the cables required by your components need to be installed, helping create a cleaner internal layout and simplifying cable management.
Key technical details include:
- 1000W power output
- Fully modular ATX power supply
- Corsair Type-5 modular connectors
- ATX 3.1 compliant
- PCIe 5.1 ready
- Native 12V-2x6 GPU power cable
- Cybenetics Gold certified
- Up to 89% overall efficiency
- 140mm Fluid Dynamic Bearing fan
- Zero RPM Mode for low-noise operation
- Manual fan speed control knob
- 105 degree C-rated Japanese electrolytic capacitors
- Continuous operation rated for temperatures up to 50 degrees C
Modern GPU Power with Native 12V-2x6
The included native 12V-2x6 GPU power cable is designed for modern graphics cards and provides a direct connection without relying on multiple traditional PCIe power cables. A dual-colour connector provides a visual indication to help confirm that the GPU-side connection is properly seated.
This makes the RM1000x SHIFT a suitable choice for users building high-end gaming systems around newer graphics cards, including compatible NVIDIA GeForce RTX 50 Series GPUs.
Efficient Power for Gaming PCs
The RM1000x SHIFT carries a Cybenetics Gold efficiency certification and can achieve up to 89% overall efficiency. Higher efficiency can help reduce wasted energy, heat generation, and unnecessary fan activity during normal operation.
The PSU is designed to maintain reliable power delivery across a wide range of system loads, making it suitable for gaming, content creation, demanding productivity applications, and other high-performance desktop workloads.
Side-Mounted Type-5 Cable Connections
Corsair's SHIFT design moves the modular cable connections to the side of the power supply rather than positioning them at the traditional rear-facing location. This can make connecting and routing cables easier once the PSU is installed.
The fully modular Type-5 connectors also use less space, while the included flexible cable kit and low-profile cable combs help keep the finished PC build neat and organised.
For compatibility with the side-mounted connectors, the PC case should provide approximately 30mm of clearance between the PSU and side panel.
Quiet Cooling with Flexible Fan Control
The 140mm Fluid Dynamic Bearing fan is designed for smooth and quiet operation. The magnetic dome structure helps reduce operating noise, while Zero RPM Mode can stop the fan completely at low to medium system loads.
For situations where additional cooling is preferred, the manual fan speed control knob allows the user to override the normal Zero RPM and low-noise behaviour. Increasing the fan speed can provide additional airflow through the PSU and help remove heat from the system.
Built for Demanding Conditions
The RM1000x SHIFT uses 105 degree C-rated Japanese industrial-grade electrolytic capacitors designed to provide stable and reliable power delivery. The internal design combines resonant LLC topology with DC-DC conversion to support efficient and dependable operation.
The power supply is also designed for continuous operation at temperatures of up to 50 degrees C, making it suitable for demanding desktop systems and environments where internal temperatures can become elevated.
Connectivity and Included Cables
The fully modular connection system gives users control over which power cables are installed in the PC. The supplied connections include:
- 1 x ATX connector
- 2 x EPS connectors
- 4 x PCIe connectors
- 12 x SATA connectors
- 4 x PATA connectors
- Native 12V-2x6 GPU power cable
The combination of multiple PCIe, SATA, PATA and EPS connections makes the 1000W Corsair PSU suitable for a wide range of modern desktop configurations and multi-drive systems.
Corsair RM1000x SHIFT for High-End PC Builds
