CORSAIR RM1000x 1000W PSU
Product description
This fully modular CORSAIR RM1000x is a low-noise ATX power supply designed for reliable desktop performance and cleaner builds. It pairs quiet operation with modular cabling so you only fit the leads you need, keeping airflow unobstructed and cable routing neat from day one.
Key features

The RM1000x aims to reduce wasted energy with Cybenetics Gold certification, rated for up to 91% efficiency according to the manufacturer, which can mean lower electricity draw and cooler running components. It meets the ATX 3.1 standard for modern systems and supports PCIe 5.1, helping to protect against transient power spikes. The unit ships with embossed, ultra-flexible cables and low-profile combs that simplify installation and improve internal aesthetics. 🔌


Technical details

Where it shines



The RM1000x performs well in rigs where a stable, high-capacity supply is needed without excessive fan noise. It keeps voltages steady under variable loads and the native GPU connector avoids adapters for recent graphics cards. The bundled embossed cables improve the final look of the build while remaining flexible during routing.
Everyday use

For typical desktop builds the unit gives dependable headroom for high-end GPUs and overclocking of a single CPU. Noise levels are subdued in light to moderate loads, making it suitable for both workstation and gaming setups. It may not be necessary for very compact or low-power systems where lower wattage PSUs are a better fit.
What it works with
The RM1000x is compatible with contemporary ATX motherboards and GPUs that accept a native 12V-2x6 connector, providing straightforward connectivity for current PCIe 5.1 graphics cards. Keep in mind that full utilisation of its capacity depends on the rest of your components and cooling arrangements.
