Introduction
The Corsair HX1500i 1500W 80 PLUS Platinum Fully Modular Power Supply (CP-9020309-IN) is engineered for high-performance desktop systems that demand substantial power capacity, advanced GPU connectivity and precise power management. It is designed for enthusiast gaming PCs, multi-GPU-capable configurations and professional workstations with demanding component requirements.
Its Intel ATX 3.1 certification and PCIe 5.1 compatibility support modern GPU power requirements. Two native 12V-2x6 cables provide direct 16-pin power connections for compatible graphics cards, while five additional PCIe 6+2-pin connectors support other compatible GPU configurations.
The fully modular design allows you to connect only the cables your system needs. Corsair iCUE software provides digital monitoring of PSU performance, fan-speed control and the ability to select single-rail or multi-rail operation.
With Platinum efficiency, a 140mm fluid dynamic bearing fan, Zero RPM mode and 105°C-rated Japanese electrolytic capacitors, the HX1500i combines high output with advanced monitoring and thermal management.
Key Features
High-Capacity 1500W Power
Delivers up to 1500W continuous output at 115–240V AC input, with a powerful single +12V rail rated at 125A for demanding CPU and GPU configurations.
80 PLUS Platinum Efficiency
Platinum certification indicates high power-conversion efficiency. Cybenetics also certifies this model at Platinum efficiency with an A- noise rating.
Dual Native 12V-2x6 Cables
Includes two native 12V-2x6 GPU power cables, each rated for up to 600W, for compatible modern graphics cards and high-performance builds.
iCUE Digital Monitoring
Connect the included internal USB cable to monitor PSU performance, control fan speed and select single-rail or multi-rail operation through Corsair iCUE software.
140mm FDB Fan and Zero RPM
The fluid dynamic bearing fan provides cooling when needed, while Zero RPM mode can eliminate fan noise at low to medium loads when cooling demand permits.
Premium Internal Components
Features 105°C-rated Japanese electrolytic capacitors, a 100,000-hour MTBF specification and a 10-year manufacturer warranty.
Digital Power Management and Cooling Technology
The HX1500i is part of Corsair's digitally monitored HXi series. With a compatible internal USB connection and Corsair iCUE software, users can monitor PSU performance, adjust fan behaviour and choose single-rail or multi-rail +12V operation.
Its 125A +12V rail provides up to 1500W for compatible system components at the specified input voltage. The ATX 3.1 design and two native 12V-2x6 cables support modern GPU power connections, while five PCIe 6+2-pin connectors offer additional flexibility for compatible hardware.
A 140mm fluid dynamic bearing fan works with Zero RPM mode to balance thermal performance and noise. At sufficiently low or moderate loads, the fan can stop entirely; it resumes operation when cooling demand rises.
The 105°C-rated Japanese electrolytic capacitors are designed for demanding operating conditions. Platinum efficiency reduces conversion losses under defined test conditions, although actual efficiency and electricity consumption depend on load and operating environment.
Technical Specifications
*Maximum output depends on AC input voltage. The manufacturer specifies 1200W maximum at 100–115V and 1500W at 115–240V. Cable lengths are nominal values with the manufacturer's stated tolerance. Always use modular cables approved for this exact PSU model.

Before You Build
- Check the complete system's power requirements and your graphics-card manufacturer's PSU recommendations before selecting a 1500W supply.
- At 100–115V input, the HX1500i is rated for a maximum total output of 1200W. Its full 1500W output is specified for 115–240V input, which covers India's nominal 230V supply.
- The PSU measures 200 × 150 × 86mm. Verify the case's PSU clearance, cable-routing space and airflow before installation.
- Use the included dual 12V-2x6 cables only with compatible graphics cards and follow the GPU manufacturer's connection instructions. Ensure each connector is fully seated.
- For iCUE monitoring, connect the included internal USB cable to a compatible motherboard USB 2.0 header and install the appropriate Corsair software.
- Never mix modular PSU cables from different models unless Corsair explicitly confirms compatibility. Matching connector shapes do not guarantee matching pinouts.
Frequently Asked Questions
