Helpful Answers ## FAQs Answers about the exact model, SKU, barcode, ATX 3.1 certification, modern GPU cable, efficiency, fan behaviour, iCUE monitoring, modular cables, protection features, fitment, and package contents. What is the exact SKU and barcode? The North American HX1000i ATX 3.1 model uses manufacturer SKU CP-9020259-NA. Its UPC / GTIN-12 retail barcode is 840006697350. Is this the HX1000i or HX1000i SHIFT? This is the standard HX1000i with conventional rear-mounted modular cable connectors. It is not the HX1000i SHIFT model with side-mounted connectors. Is the HX1000i ATX 3.1 and PCIe 5.1 certified? Yes. Corsair formally lists this revision as ATX 3.1 and PCIe 5.1 certified for current high-performance PC hardware. Does it include a cable for modern high-end graphics cards? Yes. The package includes a PCIe 5.1 12V-2x6 / 12+4-pin GPU power cable. Use only the cable supplied for this Corsair power supply or another cable explicitly approved as compatible by Corsair. What efficiency certifications does it have? The HX1000i carries an 80 PLUS Platinum efficiency certification and a Cybenetics Platinum efficiency rating. Actual efficiency varies with input voltage, load, temperature, and operating conditions. Does the cooling fan run all the time? No. The 140mm fluid dynamic bearing fan supports Zero RPM mode, allowing the fan to remain stopped during suitable low and medium load conditions. What can Corsair iCUE monitor or control? With the included internal USB cable connected, iCUE can display supported power and efficiency data, manage fan profiles and alerts, and switch between single-rail and multi-rail over-current protection modes. Is the power supply fully modular? Yes. Every DC output cable is detachable, allowing the builder to install only the cables required by the system. How many CPU and GPU power cables are included? Corsair lists two EPS / ATX12V 8-pin CPU cables, two dual PCIe 8-pin GPU cables, and one PCIe 5.1 12V-2x6 / 12+4-pin GPU cable. What protections are included? The HXi platform includes over-voltage, over-current, over-temperature, short-circuit, and over-power protection. These protections do not replace correct component selection, cable installation, ventilation, or electrical safety. Will it fit every ATX case? The unit measures 180 ร— 150 ร— 86mm. Confirm that the case supports an ATX power supply of this length and provides additional clearance for modular connectors, cable bends, the PSU shroud, and storage cages. What comes in the box? The package includes the HX1000i power supply, modular cable set, internal USB monitoring cable, AC power cord for the North American version, mounting screws, cable ties, and product documentation. Required power capacity, connector compatibility, electrical efficiency, fan behaviour, acoustic output, iCUE monitoring, and system stability vary according to the connected hardware, workload, input voltage, ambient temperature, case airflow, firmware, software, USB implementation, cable installation, and operating conditions. Confirm case clearance and component power requirements before purchase. Use only the supplied modular cables or replacements explicitly approved as compatible by Corsair. Fully seat GPU power connectors and avoid sharp bends close to the plug. Never open the power-supply enclosure. ## Details - **Price:** 469.95 CAD - **Vendor:** Corsair - **Type:** Power Supply - **Tags:** 1000W power supply, 80 PLUS Platinum, ATX 3.1, Corsair HX1000i, CP-9020259-NA, fully modular PSU, PCIe 5.1, ultra-low noise ## Variants | Variant | Price | Available | |---------|-------|-----------| | Default Title | 469.95 CAD | In stock | ## Images - Corsair HX1000i Fully Modular Ultra-Low Noise Platinum ATX Power Supply 1000W - Corsair HX1000i Fully Modular Ultra-Low Noise Platinum ATX Power Supply 1000W - Corsair HX1000i Fully Modular Ultra-Low Noise Platinum ATX Power Supply 1000W - Corsair HX1000i Fully Modular Ultra-Low Noise Platinum ATX Power Supply 1000W - Corsair HX1000i Fully Modular Ultra-Low Noise Platinum ATX Power Supply 1000W - Corsair HX1000i Fully Modular Ultra-Low Noise Platinum ATX Power Supply 1000W - Corsair HX1000i Fully Modular Ultra-Low Noise Platinum ATX Power Supply 1000W - Corsair HX1000i Fully Modular Ultra-Low Noise Platinum ATX Power Supply 1000W - Corsair HX1000i Fully Modular Ultra-Low Noise Platinum ATX Power Supply 1000W - Corsair HX1000i Fully Modular Ultra-Low Noise Platinum ATX Power Supply 1000W ## Additional Information - **Product rating count:** 0 --- > Source: [OPCbleu](https://opcbleu.ca/products/corsair-hx1000i-1000w-platinum-atx-3-1-psu-black) > Updated: 2026-08-06
