HXi SERIES
DIGITAL POWER SUPPLIES
PLATINUM POWER AT YOUR COMMAND
POWERFUL CONNECTIONS
With three EPS12V connectors and fully modular cabling, HXi Series platinum power supplies have every connection needed to power today’s most demanding PC upgrades now and into the future, including the latest generation of power-hungry graphics cards and processors.
ON THE CUTTING-EDGE
ATX 3.1 CERTIFIED
The ATX 3.1 standard demands a high level of reliability and power efficiency. While many CORSAIR PSUs meet these requirements, HXi Series PSUs are formally certified for ATX 3.1 compliance.
PCIe 5.1 12V-2x6 GPU cable included for use with modern graphics cards such as the NVIDIA® GeForce RTX™ 40 Series.
QUIET OPERATION
HXi Series PSUs combine a 140mm fluid dynamic bearing fan with Zero RPM mode support for long-lasting fan performance and near-silent operation when the fan switches off at low and medium loads – only spinning as fast as it needs to.
UNWAVERING POWER AND QUALITY
80 PLUS Platinum certified with premium 100% Japanese 105°C electrolytic capacitors, HXi PSUs ensure up to 92% efficiency for exceptional power delivery and long-term reliability with low power consumption, less noise, and cooler temperatures.
POWER AT THE READY
As a fully digital power supply, each HXi Series PSU provides clean, consistent power while minimizing coil whine and noise for stable and quiet operation.
Supporting Modern Standby sleep mode, the HXi Series takes low-load efficiency to the next level with quiet operation and extremely fast wake-from-sleep times.
80 PLUS Platinum certified
Steady power output at up to 92% efficiency, and Cybenetics-certified for lower power consumption, less noise, and cooler temperatures.
105°C-RATED CAPACITORS
Built with 100% Industrial-grade, 105°C-rated Japanese primary electrolytic capacitors for unwavering power and reliability.
iCUE SOFTWARE
YOUR SETUP AT YOUR COMMAND
With CORSAIR iCUE software, you can monitor your power supply performance, toggle single rail or multi rail mode, and control fan speed directly from your desktop.
80 PLUS Platinum Efficiency (92% Typical Load)
The 80 PLUS Platinum certification ensures the PSU converts at least 92% of AC power to usable DC power at typical loads, reducing wasted energy. This efficiency lowers electricity costs and generates less internal heat, enabling quieter operation.
ATX 3.1 & PCIe 5.1 Certified with 12V-2x6 Cable
ATX 3.1 certification ensures compatibility with modern high-power GPUs. The included PCIe 5.1 12V-2x6 cable directly powers RTX 40/50 series cards without adapters.
Zero RPM Mode with 140mm Fluid Dynamic Bearing Fan
The 140mm fluid dynamic bearing fan stops completely during low and medium loads for silent operation, only spinning when system power draw increases. This eliminates PSU noise during typical desktop use or light gaming.
Fully Modular Cables with iCUE Monitoring
All cables connect via modular ports on the PSU, allowing use of only needed cables for cleaner cable management. iCUE software provides real-time monitoring of voltage, current draw, efficiency, and fan speed through USB connection.
Use Cases
High-Power GPU Systems (RTX 5090/5080):
The 1200W capacity with ATX 3.1 certification handles RTX 50 series power spikes and sustained loads when paired with high-end CPUs. The included 12V-2x6 cable eliminates adapter compatibility concerns with modern flagship GPUs.
Silent Workstation Builds:
Zero RPM mode keeps the PSU silent during productivity workloads like coding, spreadsheets, or video editing timelines. The 140mm FDB fan only activates during intensive rendering or gaming sessions.
Multi-GPU or HEDT Workstations:
Three EPS12V connectors support high-TDP CPUs or dual-CPU motherboards, while four PCIe 8-pin connectors power multiple GPUs or professional cards. Fully modular cables enable routing only necessary connections.
Monitored Enthusiast Systems:
iCUE software integration provides real-time power monitoring for system optimization and troubleshooting. Users can track efficiency, voltage stability, and power draw per component to verify system health.
The HX1200i is 80 PLUS Platinum certified. This means the PSU wastes less energy as heat, resulting in lower electricity consumption, cooler operation, and reduced fan noise.
Yes, the HX1200i is fully compatible with NVIDIA GeForce RTX 4000 series and RTX 50 series GPUs. It is ATX 3.1 and PCIe 5.1 certified and includes a 12V-2x6 (12+4 pin) cable compatible with 40 series and 50 series GPUs.
Zero RPM mode allows the HX1200i's 140mm fluid dynamic bearing fan to remain completely off during low and medium loads, providing near-silent operation. The fan only spins up when needed under higher loads, ensuring quiet performance during typical PC usage while maintaining proper cooling when demand increases.
The HX1200i ships with the following cables: 1x 24-pin ATX cable, 2x EPS/ATX 12V 8-pin (4+4) cables, 4x PCIe 8-pin (6+2) cables, 1x 2x6-pin to12V-2x6 cable, 2x SATA cables with 4 connectors each, 2x PATA 4-pin cables with 4 connectors each, and 1x USB Type-C to internal USB header cable for iCUE connectivity.
No, you must only use the cables included with your HX1200i unless your other cables are genuine CORSAIR cables of the same type (in this case, Type 4). Using incompatible cables can cause damage to your PSU and PC components due to different pin configurations between manufacturers and even between different CORSAIR PSU series.
The HX1200i includes a 10-year warranty.
No, iCUE software is not required for operation. However, connecting the included USB Type-C cable and using iCUE software allows you to monitor power supply performance in real-time, toggle between single-rail and multi-rail OCP modes, create custom fan profiles, and set up temperature-based alerts.
The HX1200i allows you to toggle between Single Rail OCP (over-current protection) and Multi-Rail OCP through iCUE software. This feature lets you customize how the PSU manages over-current protection based on your system configuration. You can change this setting at any time without restarting the system.
The HX1200i measures 200mm in length, 150mm in width, and 86mm in height. This is a standard ATX form factor that will fit in most ATX-compatible PC cases with adequate clearance for the 200mm length.
The HX1200i uses exclusively industrial-grade Japanese 105°C-rated primary electrolytic capacitors throughout its design. These premium components can operate reliably at temperatures up to 105°C, ensuring long-term reliability and stability even under sustained high-load conditions.
The HX1200i includes two EPS12V connectors total. The included EPS/ATX 12V 8-pin cables have the capacity to support modern high-end motherboards and processors that require multiple CPU power connections.
The HX1200i includes comprehensive protection circuitry: Over-Voltage Protection (OVP) for 12V, 5V, and 3.3V rails, Over-Current Protection (OCP) on all voltage rails, Over-Temperature Protection (OTP), Short-Circuit Protection (SCP) for outputs less than 0.1 ohms, and Over-Power Protection (OPP) that activates between 115-135% of rated power.
Yes, the HX1200i is ATX 3.1 Compliant, which demands a high level of reliability and power efficiency. The ATX 3.1 standard ensures the PSU can handle the demands of modern high-performance components, including GPUs that use the 12V-2x6 connector.
The HX1200i includes a total of four PCIe 8-pin (6+2) connections, in addition to a 2x8-pin to 12V-2x6 cable. This ensures it will be able to power any modern GPU with ease.
The HX1200i provides 100A on the +12V rail with a maximum output of 1200W. Modern PC components draw the majority of their power from the +12V rail, making this the an important specification in a PSU that for a high-performance gaming PC.
