Compatible with NVIDIA 4000 series and AMD® Ryzen 7000 series GPUs
Fluid Dynamic Bearing fan with Zero RPM mode
105°C rated 100% Japanese electrolytic capacitors
10 year warranty
ATX 3.1 & PCIe 5.1 certified
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.
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.
Description
The HX1000i delivers 1000W of 80 PLUS Platinum power with ATX 3.1 and PCIe 5.1 certification — built for RTX 40/50 series GPUs with a native 12V-2x6 connector. Fully modular cables, 140mm fluid dynamic bearing fan with Zero RPM mode, and iCUE software control let you monitor efficiency and adjust fan curves. 105°C Japanese capacitors and a 10-year warranty back serious builds.
Key Features
-
ATX 3.1 & PCIe 5.1 Certified (Native 12V-2x6 Connector) Powers RTX 40/50 series GPUs without adapters — the 12V-2x6 cable delivers up to 600W directly. ATX 3.1 certification ensures transient load handling for modern GPU power spikes.
-
80 PLUS Platinum Efficiency (92% at Typical Load) Wastes less power as heat. 92% efficiency means lower electricity bills and quieter operation. Cybenetics Platinum and Noise Level A ratings confirm efficiency and low noise operation.
-
Fully Modular Design (Type 4 Cables) Connect only what you need — cleaner builds, better airflow. Includes two EPS12V, four PCIe 8-pin, eight SATA, and the 12V-2x6 cable. Compatible with CORSAIR Type 4 premium sleeved cables.
-
Zero RPM Mode (140mm Fluid Dynamic Bearing Fan) Silent at idle and low loads — the 140mm FDB fan stops completely until needed. Cybenetics Noise Level A rating means whisper-quiet operation even under gaming loads.
Use Cases
-
High-power GPU build (RTX 4090/5090, 1000W+, 12VHPWR native) Native 12V-2x6 connector delivers 600W to your GPU without adapters. ATX 3.1 certification handles transient spikes up to 200% TDP. 1000W total capacity leaves 400W+ headroom for a 14900K or 7950X, AIO pump, and RGB — all backed by 80 PLUS Platinum efficiency.
-
Quiet system builder (zero-RPM mode, Platinum/Titanium efficiency) 140mm fluid dynamic bearing fan stays off entirely at idle and low loads — Cybenetics Noise Level A confirms whisper-quiet operation even under gaming loads. 92% efficiency means less heat to exhaust. iCUE lets you tune fan curves to your liking.
-
Future-proof upgrader (ATX 3.0, headroom for next-gen GPUs) ATX 3.1 and PCIe 5.1 certification provides future-proofing for upcoming GPU standards. 1000W handles today's GPUs with ease. Fully modular Type 4 cables let you add premium sleeved cables later. 10-year warranty outlasts multiple GPU upgrade cycles.
-
Reliable workstation user (long warranty, full protections, 24/7 operation) 105°C-rated Japanese capacitors and 100,000-hour MTBF rating ensure years of continuous operation. OVP, UVP, OCP, OPP, SCP, and OTP protections safeguard expensive components. iCUE monitoring alerts you to voltage or temperature anomalies before they cause failures. 10-year warranty backs professional use.
