At the heart of the Corsair 1200W Series Low Noise PSU is a high-efficiency design: it is 80 PLUS Platinum certified, delivering up to ~92% efficiency under typical loads.
This reduces wasted energy, heat output, and helps maintain cooler, quieter system operations even under heavy loads.
Inside, the Corsair HX Series Black Desktop PSU uses only premium 100% Japanese electrolytic capacitors rated for 105 °C — a quality standard that ensures long-term reliability, stable voltage regulation, and resistance to thermal stress.
This makes HX1200i Fully Modular Ultra-Low Noise PSU a robust choice for long-duration workloads such as rendering, simulation, video editing, or gaming marathons.
One of the greatest strengths of the HX1200i Fully Modular Ultra-Low Noise PSU is its fully modular cabling system.
Modular design lets you attach only the cables your build needs, significantly reducing clutter inside the case and improving airflow.
The included cable set supports modern GPU standards — including multiple 6+2-pin PCIe connectors and a 12VHPWR / PCIe 5.1 ready cable — ensuring compatibility with today’s power-hungry graphics cards and next-gen GPUs.
In addition to PCIe, connections for EPS (CPU), SATA, Molex/PATA, and other peripherals are available, making HX1200i suitable for high-end workstations, multi-GPU rigs, or complex storage-heavy configurations.
Cooling and acoustics are carefully balanced. A 140 mm fluid-dynamic-bearing fan provides efficient airflow and heat dissipation.
Through “Zero RPM Mode,” the fan of the Corsair HX 80 Plus Platinum PSU remains completely off under light and medium loads — making the PSU nearly silent during system idle, browsing, or light productivity tasks.
Under load, the fan ramps up only as much as needed, offering a quiet but effective cooling solution, ideal for noise-sensitive environments such as video editing suites, living-room gaming PCs, or quiet workstations.
HX1200i Fully Modular Ultra-Low Noise PSU also meets modern power standards: it is ATX 3.1 certified and PCIe 5.1 ready, ensuring compatibility with current and future high-power hardware — including next-generation graphics cards and CPUs that demand stable, high-wattage supply and transient load handling.
The PSU’s fully digital design and active power management help minimize coil whine and electronic noise, delivering smooth, clean power delivery that protects delicate components.
Safety and reliability are built in: the Corsair Fully Modular Ultra Low Noise PSU offers comprehensive protections (over-voltage, under-voltage, over-power, short-circuit, over-temperature, etc.), high MTBF (~100,000 hours), and is backed by a long 10-year manufacturer warranty.
Whether you build a flagship gaming rig, a rendering workstation, or a multi-GPU deep-learning system — HX1200i Fully Modular Ultra-Low Noise PSU is built to serve as a dependable power foundation for years.
For users who care about aesthetics as much as performance, the modular cables (flat / low-profile design) help in achieving a clean, organized build.
Combined with modern connectors and ample headroom for power, HX1200i Fully Modular Ultra-Low Noise PSU balances power, silence, efficiency, and flexibility — traits that make it a top-tier PSU choice for demanding builds.
The HX1200i Fully Modular Ultra-Low Noise PSU isn’t just a power supply — it’s a high-performance, future-proof platform.
If you’re building a cutting-edge PC and want a power supply that delivers ample wattage, clean and efficient delivery, modular cabling, silent operation, and long-term reliability, HX1200i Fully Modular Ultra-Low Noise PSU is among the best in its class.
