At its core, the HX1500i delivers a powerful 1500 W continuous output via a robust +12 V rail capable of delivering up to 125 A. This ensures stable, ample power even for flagship CPUs, multiple GPUs, heavy storage arrays, and overclocked components — making it ideal for extreme gaming builds, AI/ML workstations, rendering machines, or future-proof multi-GPU setups.
Efficiency is a key advantage. HX1500i is certified 80 PLUS Platinum, yielding up to ~92% power conversion efficiency under typical loads. This translates to reduced wasted energy, lower heat output, and quieter thermal conditions — benefits that many users notice both in cooling performance and energy bills. Internally, the unit uses 100% Japanese 105 °C-rated electrolytic capacitors, a hallmark of premium PSU quality — ensuring long-term voltage stability, resilience under high loads, and dependable performance over years of heavy usage.
Cable management and build aesthetics are simplified thanks to the fully modular cabling design. Only the necessary cables are connected, resulting in cleaner interior layouts and improved airflow — a big plus for large builds, full-tower cases, or systems with many components. The included cable set supports modern & future-ready standards: multiple PCIe (6+2) connectors, EPS CPU connectors, SATA, PATA, and a dedicated 12VHPWR / PCIe 5.0-ready cable — making HX1500i suitable even for next-generation GPUs and high-power configurations.
Despite its high power output, the HX1500i prioritizes silent operation. A 140 mm fluid-dynamic bearing fan with “Zero RPM Mode” remains off under light to moderate loads, rendering the PSU virtually silent during typical usage like browsing, office work, or low-load tasks. When the system demands more power, the fan gradually ramps up to provide adequate cooling, balancing performance and acoustic comfort — ideal for noise-sensitive environments like studios or living-room builds.
Compatibility and future-proofing are built in. The PSU conforms to ATX 3.0 / PCIe 5.0 / 12VHPWR standards, ensuring compatibility with both current and upcoming high-power hardware. It supports multiple EPS, PCIe, SATA, and peripheral connections — ready for complex, high-demand systems. On top of that, the unit includes comprehensive power protections (over-voltage, under-voltage, over-power, short-circuit, etc.), features a fully digital power delivery design for clean, stable output, and carries a 10-year warranty with a rated MTBF of 100,000 hours, highlighting confidence in long-term durability.
The PSU’s form factor fits standard ATX chassis (dimensions: ~200 × 150 × 86 mm), and its modular, sleeved/flat black cables help maintain a clean, professional-looking build. For users building high-end gaming rigs, multi-GPU rendering systems, or power-hungry workstations — where stable, ample, and efficient power is non-negotiable — the HX1500i delivers on all fronts: power, flexibility, efficiency, silence, and reliability.
The Corsair HX1500i is not just a power supply — it’s a backbone for performance PC builds. It gives you the confidence to push hardware to its limits, while ensuring clean power delivery, minimal noise, optimum efficiency, and long-term resilience. For anyone serious about their build — whether gaming, content creation, or workstation — HX1500i is a top-tier PSU choice that’s built to handle today’s and tomorrow’s demands.
