CORSAIR RM1200e 1200W 80 PLUS Gold Fully Modular Gen 5 Power Supply – Black | RM1200e
The CORSAIR RM1200e is a powerful 1200W fully modular power supply featuring 80 PLUS Gold efficiency, ATX 3.1 certification, and PCIe 5.1 compatibility. Its native 12V-2x6 GPU cable, Zero RPM fan mode, Japanese 105°C capacitors, and compact construction make it ideal for flagship gaming PCs and demanding workstations.
Product Overview
The CORSAIR RM1200e delivers stable and efficient power for flagship gaming computers, professional workstations, and other systems fitted with power-hungry processors and graphics cards. Its substantial 1200W continuous output provides excellent headroom for premium components, future upgrades, extensive cooling systems, and multiple storage devices.
A fully modular cable system allows builders to connect only the cables required by their configuration. This helps reduce cable clutter, simplify installation, and improve airflow throughout the case. The included cables provide dual EPS processor connections, conventional PCIe 6+2-pin connectors, SATA power, PATA power, and a native 12V-2x6 graphics-card connection. corsair.com
The RM1200e is Intel ATX 3.1 certified and PCIe 5.1 compatible, allowing it to handle the transient power demands of modern graphics hardware. Its native 12V-2x6 cable supports compatible current-generation GPUs without requiring multiple adapter cables. corsair.com
An 80 PLUS Gold efficiency rating provides up to 90% operating efficiency, reducing unnecessary power consumption and heat generation. The internal platform uses resonant LLC topology, DC-to-DC conversion, and 100% industrial-grade Japanese electrolytic capacitors rated for 105°C to provide consistent electrical performance and long-term reliability.
Its low-noise cooling system includes a Zero RPM mode that stops the fan during lighter workloads for near-silent operation. Microsoft Modern Standby support also enables fast wake-from-sleep performance and improved low-load efficiency. corsair.com
