CORSAIR’s iCUE 4 compatibility list names 14 power supplies: five AXi models, five HXi models, and four RMi models. They can expose PSU monitoring, cooling controls, temperature alerts, and rail-related device settings in iCUE. The published list is specifically for iCUE 4 and was updated February 29, 2024, so it should not be treated as a complete list of every newer generation or regional SKU.
Before buying or installing one, verify the complete model name and suffix in CORSAIR’s current support documentation, then confirm operating-system support, USB connectivity, wattage, connectors, and form factor for your build.
The Corsair PSU models listed as iCUE-compatible
CORSAIR’s named compatibility list for iCUE 4 identifies specific models rather than declaring that every CORSAIR power supply works with the software. The list was updated on February 29, 2024. That date and software version matter: a newer product family, a revised regional SKU, or a later iCUE release may have different support.

| Series | Models named on CORSAIR’s iCUE 4 list |
|---|---|
| AXi | AX760i, AX860i, AX1200i, AX1500i, AX1600i |
| HXi | HX750i, HX850i, HX1000i, HX1200i, HX1500i |
| RMi | RM650i, RM750i, RM850i, RM1000i |
This is the precise model-level evidence available for those products. It does not establish that every AX, HX, RM, or other CORSAIR family member is iCUE-compatible. If the label contains a different suffix, use the exact product name in current CORSAIR support material instead of assuming that a similar-looking model behaves the same way.

What the “i” suffix means—and why model verification still matters
CORSAIR’s smart-PSU explanation says that an “i” in the model name denotes iCUE compatibility. That rule is a useful first filter: AXi, HXi, and RMi products are the families represented in the published list above. It is not a substitute for checking the complete model number.
Model names can differ by generation, region, connector package, or revision. The compatibility list found for this guide is explicitly an iCUE 4 list, while CORSAIR’s broader “i” explanation is family-level guidance. Treat the exact named-model entry as the stronger basis for a purchase decision. When a product page, retail listing, or box uses an abbreviated name, locate the full designation on the PSU label or specification sheet before you decide that it will appear in iCUE.
What iCUE can do with a compatible power supply
A supported PSU is more than a fan with a lighting-related feature. CORSAIR’s setup documentation describes several categories of information and control that become available after the PSU is connected and recognized by iCUE.

iCUE can place PSU readings in dashboard widgets and sensor tiles. These give you a live view of the measurements exposed by the unit, making it possible to watch PSU behavior alongside other monitored PC components. The exact sensors and labels shown depend on the device and the iCUE version.
Monitoring is useful when diagnosing a system that becomes unstable under load, checking how temperature changes during a long session, or confirming that the PSU is visible to the software. It is software telemetry from the PSU; it is not an independent electrical-performance test.

Cooling presets and fan curves
The software can provide cooling presets and user-configured fan curves for compatible units. A preset is a ready-made behavior, while a curve lets you define how fan response changes as the PSU sensor temperature rises.
Selected cooling settings are saved to the PSU itself, so the unit can continue using them when iCUE is not running. That persistence is important for systems that do not keep the application open continuously. It also means you should review a profile before saving it: a curve that is too aggressive can add unnecessary fan noise, while one that delays fan response may not suit your operating conditions.

Temperature-based alerts
Alerts can be tied to the PSU’s temperature. CORSAIR describes actions that may include setting the fan to full speed, changing iCUE-controlled RGB lighting, running a file, or shutting down the computer.
Shutdown automation requires particular care. CORSAIR warns that setting the shutdown threshold too low can cause an immediate shutdown when the PSU sensor reaches that temperature. Choose a threshold deliberately and test the resulting behavior before relying on it for protection. An unexpected shutdown can interrupt work, corrupt data, or make it appear that the PSU has failed when the trigger is actually an alert rule.
Rail and overcurrent-protection settings
Device settings can include single-rail or multi-rail PSU mode and individual-rail overcurrent-protection settings. These are advanced electrical-protection controls, not ordinary fan preferences.
Rank #3
- Fully Modular: Reliable and efficient low-noise power supply with fully modular cabling, so you only have to connect the cables your system needs.
- Cybenetics Gold-Certified: Rated for up to 91% efficiency, resulting in lower power consumption, less noise, and cooler temperatures.
- ATX 3.1 Compliant: Compliant with the ATX 3.1 power standard from Intel, supporting PCIe 5.1 and resisting transient power spikes.

CORSAIR’s support guide gives this warning: “We do NOT recommend changing these settings unless you absolutely know what you are doing.” Leave the defaults in place unless you understand the implications for your hardware and have a specific reason to change them. If you do change a setting, record the original value so you can restore it during troubleshooting.
Zero-RPM mode is not proof of iCUE support
Zero-RPM mode and iCUE compatibility are separate features. In zero-RPM operation, the PSU fan remains stopped while cooling demand is low and starts as temperature rises. CORSAIR identifies zero-RPM support in AXi and AX, HXi and HX, RMx and RM, SF, and selected TX and TXm families.
A PSU can therefore have zero-RPM behavior without being controllable through iCUE. CORSAIR specifically distinguishes an i-series unit whose zero-RPM setting can be enabled in iCUE from a non-iCUE PSU that has zero-RPM but cannot have that feature controlled in the application.
Use the exact model list to establish software compatibility. Use zero-RPM documentation only to establish that the fan may stop automatically under suitable thermal conditions. Do not infer one from the other.
How to connect and configure a compatible PSU
CORSAIR’s HXi quick-start material shows a USB connection between the PSU and the motherboard, followed by device selection in iCUE. The practical sequence is:
Rank #4
- Fully Modular PSU: Reliable and efficient, low-noise power supply with fully modular cabling, so you only have to connect the cables your system build needs.
- Intel ATX 3.1 Certified: Compliant with the ATX 3.1 power standard, supporting PCIe 5.1 platform withstands 2x transient power excursions from the GPU.
- Keeps Quiet: A 120mm rifle bearing fan with a specially calculated fan curve keeps fan noise down, even when operating at full load.
- 105°C-Rated Capacitors: Delivers steady, reliable power and dependable electrical performance.
- Modern Standby Compatible: Extremely fast wake-from-sleep times and better low-load efficiency.
- Confirm the model. Read the full PSU model and suffix from the unit or its documentation. Compare it with the current CORSAIR compatibility information; the iCUE 4 list specifically names AX760i, AX860i, AX1200i, AX1500i, AX1600i, HX750i, HX850i, HX1000i, HX1200i, HX1500i, RM650i, RM750i, RM850i, and RM1000i.
- Check the platform. Verify that your operating system and installed iCUE version support PSU devices. Do not assume that support shown for Windows applies identically to macOS.
- Connect the PSU to the motherboard. Follow the PSU’s quick-start instructions and use the designated USB connection. The connection is separate from the motherboard’s main power and CPU power leads; both power delivery and the data connection must be installed correctly.
- Start iCUE. Launch the installed iCUE application after the computer is fully assembled and powered on.
- Select the PSU device. In iCUE, choose the detected PSU to open its dashboard, sensors, cooling controls, alerts, and device settings.
- Review detection before changing settings. Confirm that sensor tiles update and that the displayed model matches the unit installed in the case. If the device is missing, troubleshoot the connection and software support before changing rail or protection settings.
- Configure only the features you need. Set a cooling preset or curve, create temperature alerts if required, and leave advanced rail settings at their defaults unless you have the necessary electrical knowledge.
- Save and observe. Because selected cooling settings can be stored on the PSU, verify the fan behavior after closing iCUE or restarting the computer. Watch the temperature and alert behavior before treating the profile as finished.
Windows, macOS, and version limits
The operating system is part of the compatibility decision. CORSAIR’s iCUE 4 compatibility list says that the macOS version supports only the listed HID and audio products. PSUs appear in the separate DIY PC components category, so the list does not establish PSU controls through iCUE 4 on macOS.
For a Mac-based setup, do not promise that a listed AXi, HXi, or RMi PSU will expose its controls in iCUE 4. Confirm current macOS support for the specific model and software release before purchase. A unit can be physically compatible with a PC build yet lack the expected software path on a particular operating system.
The same caution applies to later iCUE releases and newer PSU generations. The February 29, 2024 list is a dated iCUE 4 reference, not a guarantee of present-day cross-version or cross-region coverage. Current CORSAIR documentation for the exact product should take precedence.
How to choose among AXi, HXi, and RMi models
All three families in the named list can provide the relevant iCUE integration, but compatibility alone does not identify the right wattage or physical unit for a build. Select by the requirements of the complete system.

The available compatibility evidence does not establish a winner among AXi, HXi, and RMi models, nor does it independently validate electrical performance, acoustic output, or value. Those decisions require the model’s own current specifications or reliable testing. A higher wattage number is not automatically a better choice if the unit does not fit the case or provide the connectors your components need.

When a listed model is a sensible starting point
Start with the exact listed model when iCUE integration is a priority and the unit’s capacity, connectors, and dimensions match the build. This approach minimizes the risk of buying a physically suitable PSU that lacks software support.
When the list is not enough
If you are considering a newer product, a regional variant, or a model whose suffix is missing from the documentation, pause the purchase and confirm current support. Do not extend compatibility from an older family name alone. Likewise, do not select a unit solely because it advertises zero-RPM operation.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Modular cable compatibility: do not mix by appearance
Replacing or extending modular PSU cables requires an exact compatibility check. CORSAIR’s cable FAQ states that RMx Shift PSUs use Type 5 Micro-Fit cables and that Type 5 cables are not compatible with Type 3 and Type 4 PSUs.
Connector shape or brand name is not enough to establish electrical compatibility. A cable that physically plugs in can still have a different pinout. Before reusing cables from another PSU, identify the exact PSU model and cable type, then follow CORSAIR’s cable guidance for that combination. When the documentation does not confirm a match, use the cables supplied with the PSU or obtain a specifically identified replacement rather than guessing.
Troubleshooting common iCUE and PSU problems
The PSU does not appear in iCUE
- Recheck the complete model number and suffix against current CORSAIR support information. Similar family names do not prove compatibility.
- Verify the motherboard USB connection shown in the PSU’s quick-start instructions. A unit can deliver power while its data connection is absent or incorrectly connected.
- Confirm the installed iCUE version and operating system. The published model list is for iCUE 4, and its macOS note does not establish PSU support.
- Restart the computer and reopen iCUE after checking the connection. If the device remains absent, avoid changing advanced PSU settings and seek model-specific support.
The fan runs, but iCUE does not control it
- Determine whether the PSU is merely using built-in zero-RPM behavior. Zero-RPM support alone does not provide iCUE control.
- Confirm that the unit is one of the iCUE-compatible models and that iCUE has selected the correct device.
- Check whether a saved cooling profile is active on the PSU. Stored settings can continue operating when iCUE is closed.
The computer shuts down after creating an alert
- Open the PSU alert configuration and review the temperature threshold and selected action.
- Raise or remove an overly low shutdown threshold; CORSAIR warns that the PSU can shut down immediately when its sensor reaches the configured value.
- After changing the alert, monitor the PSU temperature and confirm that the intended action occurs only at an appropriate threshold.
A cable replacement causes concern
- Stop using the replacement until its type is confirmed for the exact PSU.
- Pay particular attention to the Type 5 versus Type 3 and Type 4 distinction documented for CORSAIR modular cables.
- Restore the original cable set or obtain a model-specific replacement when compatibility cannot be established.
A practical pre-purchase checklist
- Write down the full PSU model, including every suffix.
- Check the model against current CORSAIR support documentation, not only a retailer’s abbreviated title.
- Note that the published named list is an iCUE 4 reference updated February 29, 2024.
- Confirm operating-system and iCUE-version support, especially if the computer uses macOS.
- Verify wattage, connectors, form factor, case clearance, and cable-routing space for the complete build.
- Decide whether you need monitoring, fan curves, temperature alerts, or advanced rail settings.
- Do not treat zero-RPM support as evidence of iCUE compatibility.
- Check every modular cable against the exact PSU model and documented cable type.
- Leave rail and overcurrent-protection settings unchanged unless you understand their electrical consequences.
Bottom line for compatibility decisions
The clearest confirmed iCUE choices in the available CORSAIR documentation are the AXi, HXi, and RMi models named in the iCUE 4 list: AX760i, AX860i, AX1200i, AX1500i, AX1600i; HX750i, HX850i, HX1000i, HX1200i, HX1500i; and RM650i, RM750i, RM850i, RM1000i. Compatible units can expose monitoring, cooling, temperature alerts, and device settings, but software support depends on the exact model, iCUE version, and operating system. Verify newer generations and regional SKUs with current CORSAIR documentation before committing to a purchase.
