Overview
- The Corsair HX1200i is a premium, fully modular power supply built for systems that demand stability, efficiency, and clean power delivery. With 1200W of continuous output and Intel ATX 3.1 certification, it supports next-generation high-end graphics cards and multi-GPU configurations without compromise.
Designed for silence and efficiency, the HX1200i features a 140mm Fluid Dynamic Bearing fan with zero RPM mode, which disengages the fan entirely during light system loads. This combination delivers true silent operation when you need it most. Platinum efficiency means less energy wasted as heat, lower electricity bills, and reduced strain on cooling systems.
Fully modular cabling lets you connect only the cables your build requires, eliminating cable clutter, improving airflow, and making cable management intuitive. The power supply uses 100% Japanese electrolytic capacitors rated to 105°C, ensuring long-term reliability even in warm environments. Backed by a 10-year warranty and an MTBF rating of 100,000 hours, the HX1200i is built to outlast most system upgrades.

FAQs
What does fully modular mean on a power supply?
Fully modular means every cable connects to the power supply via a connector. You only install the cables your build requires, eliminating excess cables, improving case airflow, and making cable management easier.
Is the Corsair HX1200i suitable for high-end gaming and content creation builds?
Yes. With 1200W continuous output, Intel ATX 3.1 certification, dual 12V cables, and multi-GPU support, the HX1200i is designed for high-performance systems including gaming PCs with RTX 40-series graphics cards and professional workstations.
What is zero RPM mode and why does it matter?
Zero RPM mode disengages the fan during light system loads, eliminating noise completely. This is ideal for office work, browsing, and gaming at moderate frame rates, while the fan automatically restarts under heavy load.
What does Platinum efficiency mean?
Platinum efficiency (80 PLUS Platinum) means the power supply converts at least 90% of input AC power to usable DC power. This reduces energy waste, lowers electricity costs, and minimises heat output compared to less efficient models.
How does the 10-year warranty compare to other power supplies?
A 10-year warranty is among the longest in the industry and reflects Corsair's confidence in the HX1200i's reliability. Combined with the 100,000-hour MTBF rating and premium Japanese capacitors, it provides substantial peace of mind.
Is this power supply compatible with PCIe 5.0 and next-generation graphics cards?
Yes. The HX1200i is Intel ATX 3.1 certified and PCIe 5.1 compatible, supporting next-generation GPUs. The dual 12V-2x6 cables deliver the high power demanded by modern high-end graphics cards.
Can the HX1200i support dual graphics cards?
Yes. The HX1200i is multi-GPU ready with five 8-pin PCIe connectors and dual 12V-2x6 cables, making it suitable for builds requiring two or more dedicated graphics cards.
