The Corsair RM1200e is a high-performance 1200W ATX power supply designed for gaming PCs, workstations and enthusiast builds. Featuring a fully modular design, it helps reduce cable clutter and improve airflow for cleaner system builds. The native 12V-2x6 cable and PinProtect per-pin 12V-2x6 OCP provide reliable power delivery for modern high-performance components, while the low-noise cooling design and 3D-Y fan help maintain efficient and quiet operation. Finished in Black, the RM1200e is an ideal power solution for demanding PC systems.
CORSAIR PINPROTECT
The RM1200e features cutting-edge protection for modern graphics cards with PinProtect 12V-2x6 overcurrent protection (OCP). It monitors each individual pin carrying power to the GPU in real-time to protect it from unexpected power fluctuations.
3D Y-PATTERN FAN GRILLE
A three-dimensional Y-pattern fan grille inspired by CORSAIR FRAME series cases offers excellent airflow with minimal resistance, improving cooling performance with less fan activity and quieter operation compared to PSUs with a 2D fan grille.
PREMIUM DEBOSSED CABLE KIT
High-quality debossed cables with low-profile combs let you easily and precisely route cables exactly where they need to go for a super-clean build.
CYBENETICS PLATINUM CERTIFIED
Steady power output at up to 91% efficiency and Cybenetics™ Platinum certified for lower power consumption, less noise, and cooler temperatures.
ATX 3.1 & PCIe COMPLIANT
With 1200W of reliable power, take on demanding builds with confidence. It is also ATX 3.1 certified and PCIe 5.1 compliant with a 10-year warranty, making it a power supply that will last through several builds. Built-in protections for dangerous current, voltage, short circuits, and temperature ensure reliable operation.
ZERO RPM MODE
Under low and moderate loads, the 140mm fan inside the RM1200e does not spin, allowing for truly silent computing for everyday tasks. When the load increases, its custom-tuned fan curve ensures continuous low-noise operation.
MADE WITH HIGH-QUALITY COMPONENTS
The RM1200e offers advanced features and is made with premium components including 105°C-rated Japanese capacitors and a robust LLC half-bridge topology for improved efficiency.
