## Key Points

- Corsair HX1000i Shift Crystal is a 1000W PSU with Cybenetics Platinum efficiency and ATX 3.1/PCIe 5.1 support
- PinProtect+ technology monitors current on each of the six 12V-2×6 connector pins, shutting down the GPU during persistent overload
- Current threshold is adjustable from 7 to 10A (default 9.5A), delay from 10 to 180s (default 30s)
- Integrated iCUE LINK hub supports up to 24 devices (12 per channel) without an external controller
- Transparent polycarbonate windows, RGB lighting, 140mm Magnetic Dome fan, Zero RPM mode
- Price in the US is $339.99, 10-year warranty, up to 91% efficiency

At Computex 2026, Corsair unveiled the HX1000i Shift Crystal, a power supply based on the HXi Shift platform featuring transparent polycarbonate windows and the proprietary PinProtect+ pin-level overcurrent protection system. The new unit is Cybenetics Platinum efficiency certified, meets ATX 3.1 and PCIe 5.1 requirements, and is managed via the Corsair iCUE application. The unit is rated at 1000W and is priced at $339.99 on the US Corsair store, backed by a 10-year warranty.

### PinProtect+: Current Control on Each of the Six Pins

The model's key feature is PinProtect+ technology, which monitors current on each of the six +12V pins of the 12V-2×6 connector rather than just the total value. Metrics for each pin are displayed in the iCUE interface. If a set threshold is exceeded, a delay countdown starts and a notification is triggered; if the elevated current persists through the end of the delay, the system limits power to the cable, leading to GPU shutdown and reducing the risk of equipment damage. The fan ramps up to maximum speed, and the RGB lighting shifts to red to signal the protection trigger. The delay prevents false positives during transient spikes: if the current returns to normal, no shutdown occurs.

### Customizable Thresholds and Connector Diagnostics

Users can set current thresholds in the range of 7 to 10 A (default 9.5 A) and delay durations from 10 to 180 seconds (default 30 s). An event log and connection status check are available in the app. After protection triggers, the manufacturer recommends inspecting the cable's two-tone connectors: visible gray areas indicate incomplete insertion, which is a common cause of individual pin overload.

### Transparent Chassis and Component Visualization

The HX1000i Shift Crystal features transparent polycarbonate inserts on three sides, revealing internal components including Japanese electrolytic capacitors rated for temperatures up to 105 °C. An integrated 140mm Magnetic Dome bearing fan is enhanced with customizable RGB lighting, which also serves as a status indicator for the PinProtect+ system. The fan grille with a 3D Y-shaped pattern reduces airflow resistance, while the Zero RPM mode halts the fan under light loads.

### Integrated iCUE LINK Hub

The PSU includes a built-in iCUE LINK hub, allowing compatible devices to be connected without a separate hub or extra PCIe power cables. The dual-channel architecture supports up to 24 devices—12 per channel; they are daisy-chained and automatically recognized by the iCUE software, where fan speeds and RGB lighting are managed. A USB connection to the motherboard is required for software control. Side-panel connectors provide easy access to modular Corsair Type-5 cables with low-profile combs, and the modular design ensures only necessary cables are used for specific builds.

### Efficiency and Transient Load Support

The Corsair HX1000i Shift Crystal boasts up to 91% efficiency, and support for transient load spikes meets ATX 3.1 standards. The combination of per-pin monitoring, customizable thresholds, the integrated iCUE LINK hub, and the transparent chassis makes this model ideal for enthusiasts who value both the protection of expensive GPUs and the visual aesthetics of their build.

## FAQ

### What is PinProtect+ in the Corsair HX1000i Shift Crystal PSU?

It is a per-pin overcurrent protection system that monitors current on each of the six +12V pins of the 12V-2×6 connector; if the limit is persistently exceeded, it limits power and shuts down the GPU.

### What thresholds and delays can be set in PinProtect+?

The current threshold can be set between 7 and 10 A (default 9.5 A), and the delay duration from 10 to 180 seconds (default 30 s).

### How many devices does the integrated iCUE LINK hub support?

Up to 24 compatible devices—12 per channel in a dual-channel architecture; they connect in a daisy-chain and are recognized by iCUE.

### What are the power, efficiency, and price of the Corsair HX1000i Shift Crystal?

Rated at 1000W, up to 91% efficiency, Cybenetics Platinum certified, price $339.99 in the US Corsair store, with a 10-year warranty.

### What makes the transparent chassis special?

It has transparent polycarbonate inserts on three sides to display components, including 105°C-rated Japanese capacitors; the 140mm fan's RGB lighting doubles as a PinProtect+ status indicator.
