1000W ATX 3.1 PSU for high-end builds

The Corsair RM1000x Shift delivers 1000 W through a fully modular design that meets ATX 3.1 and PCIe 5.1 requirements. A side-mounted connector panel places every cable port within easy reach, simplifying routing in tight chassis. The unit includes a native 12V-2x6 cable ready for modern GPUs such as the NVIDIA RTX 50 Series. 80 PLUS Gold certification confirms efficient power conversion across typical loads.

Sustained output at full rated wattage

Under continuous load the power supply maintains its 1000 W rating without throttling, thanks to a 140 mm fluid dynamic bearing fan governed by a calibrated curve. The fan profile balances airflow and acoustic output so the unit stays within Cybenetics A noise limits even during prolonged stress. Stable +12 V, +5 V and +3.3 V rails keep voltage regulation tight when the system draws maximum current for extended periods.

Low noise and efficient thermals

The 140 mm fluid dynamic bearing fan spins only as fast as thermal sensors demand, keeping operational noise at Cybenetics A levels during normal use. At typical desktop and gaming loads the fan often runs at low RPM, reducing audible output while maintaining safe component temperatures. 80 PLUS Gold efficiency reduces waste heat, lowering overall power draw from the wall across the 100-240 V input range.
