Overview

The CORSAIR HX1500i 2025 Model is a fully modular 1500W power supply designed for high-end PC builds. It carries Cybenetics Platinum certification, ensuring excellent power conversion efficiency and stable output. Compliant with Intel ATX 3.1 and PCIe 5.1 standards, it includes a dedicated 12V-2x6 cable for next-generation graphics cards. Equipped with a 140mm fluid dynamic bearing (FDB) fan, the HX1500i features a Zero RPM mode that stops the fan entirely under low to medium loads, delivering near-silent operation. Full digital control via CORSAIR iCUE software allows custom fan curves, real-time power monitoring, and switching between single-rail and multi-rail overcurrent protection (OCP). In the market, 1500W PSUs occupy the ultra-high-end segment. This unit is ideal for multi-GPU setups, overclocked workstations, or users who want headroom for future upgrades without replacing the power supply.

Compatibility Guide

The HX1500i follows the standard ATX form factor and fits most ATX and E-ATX cases. However, its depth is approximately 200mm, so check your case's PSU clearance before purchase. Connector availability includes: Main: 24-pin ATX CPU: EPS12V 8-pin ×2 PCIe: 6+2-pin ×6, 12V-2x6 (12+4-pin) ×1 SATA: 12 connectors * Peripheral 4-pin: 4 connectors ATX 3.1 compliance ensures direct compatibility with PCIe Gen 5.0/5.1 graphics cards. The included 12V-2x6 cable supports up to 600W delivery.

Best Use Cases

High-end gaming PC builders: For dual GeForce RTX 5090 or RTX 4090 setups, 1500W provides ample headroom. The native 12V-2x6 cable simplifies wiring and reduces adapter clutter. Creative workstation users: Video editing, 3D rendering, and AI workloads push both CPU and GPU to maximum load. The HX1500i's Japanese capacitors and 10-year warranty ensure long-term reliability under sustained stress. * Future-proofing enthusiasts: If you plan to gradually upgrade from a mid-range to a high-end system over several years, investing in a 1500W PSU now avoids the hassle of swapping the power supply later.

Things to Consider

1500W is overkill for a typical single-GPU build (e.g., RTX 5070 class). For such configurations, an 850W–1000W unit offers better value. The PSU's 200mm depth may not fit compact ATX or mid-tower cases. Always verify your case's maximum PSU length before purchasing. Competitors include the Seasonic Prime TX-1600 and be quiet! Dark Power Pro 13 1500W. The HX1500i stands out with iCUE integration and fully digital control, but it is priced at a premium. While ATX 3.1 compliant, the unit works with older ATX 2.x motherboards and cases. However, the 12V-2x6 connector requires a compatible graphics card to be fully utilized.
