CORSAIR RM1000e 1000W 80+ Gold ATX 3.1 Fully Modular Power Supply

The Corsair RM1000e is a 1000-watt fully modular power supply from the RMe Series, designed for enthusiast PC builders who demand reliable, efficient, and quiet power delivery. Carrying formal Intel ATX 3.1 certification and PCIe 5.1 compatibility, the RM1000e is ready for today's high-end graphics cards and the next generation of components that demand transient power headroom beyond rated TDP. One of the standout features of the RM1000e is its native 12V-2x6 GPU power cable, capable of delivering up to 600W to a single graphics card. This connector meets the requirements of current flagship GPUs without the need for adapters, reducing the risk of connector heat-related issues common with daisy-chained alternatives. Three additional PCIe 6+2-pin connectors are also included, providing flexibility for multi-GPU or dual-connector GPU configurations. The RMe Series unit is Cybenetics Gold certified, achieving up to 90% power conversion efficiency. This translates to less wasted energy as heat, lower operating temperatures, and reduced fan activity during typical workloads. The 120mm rifle-bearing fan operates on a carefully tuned fan curve, staying near-silent at light-to-moderate loads and ramping up only when thermal conditions require it — all within a compact 140mm chassis that makes cable routing easier inside modern mid-tower and full-tower cases. Internally, the RM1000e is built around a resonant LLC topology with DC-to-DC conversion stages and 105°C-rated industrial-grade Japanese capacitors. This topology provides stable voltage regulation across the 12V, 5V, and 3.3V rails under varying load conditions. The unit also supports Modern Standby (formerly Connected Standby), enabling fast wake- sleep response times and improved efficiency at low loads — a practical advantage in always-connected desktop systems. Fully modular cabling means every cable connector, including the ATX main power connector, is detachable. Only cables your build actually needs are installed, keeping the interior tidy and airflow unobstructed. Ultra-flexible embossed cables with included low-profile combs further simplify neat routing.
