Corsair RM1000x 1000W 80 Plus Gold Fully Modular ATX Power Supply (Black)

The Corsair RM1000x 1000W 80 Plus Gold Fully Modular ATX Power Supply in black is engineered for demanding desktop builds that require clean, stable power delivery without compromise. Rated at 1000 watts with a single +12V rail design, it is well suited to high-end gaming rigs, content creation workstations, and multi-GPU configurations where power headroom and rail stability matter most. As a fully modular unit, every cable — including the 24-pin ATX connector — can be detached when not in use. This means you connect only what your system actually needs, reducing cable clutter inside the chassis and improving airflow. Cleaner builds run cooler, and the RM1000x makes cable management straightforward regardless of whether you are working in a mid-tower or a full-tower case. The 80 Plus Gold efficiency rating indicates that this unit operates at 87% efficiency or higher under typical loads, with peak efficiency reaching 90% at 50% load. Higher efficiency translates directly to less wasted energy as heat, lower electricity draw from the wall, and a quieter fan that does not need to spin as hard to keep temperatures in check. The result is a quieter, more energy-conscious system over hours of sustained use. The black finish and flat modular cables complement contemporary case aesthetics, keeping internal presentation consistent with modern builds. The ATX form factor ensures broad compatibility with standard desktop enclosures.
