CORSAIR RM1200x Shift 1200W 80+ Gold ATX 3.1 Fully Modular Power Supply ( White )

The CORSAIR RM1200x Shift is a 1200-watt fully modular power supply from the RMx SHIFT Series, designed for enthusiast and high-performance PC builds that demand clean, stable power delivery alongside thoughtful cable management. Its defining feature is a side-mounted modular connector panel, which repositions all cable ports from the rear face of the unit to the side. This makes it noticeably easier to route and manage cables inside compatible cases, reducing clutter and improving airflow around the power supply bay. The RM1200x Shift carries ATX 3.1 certification, meeting the latest Intel power-delivery specifications that address transient power spikes common with modern high-end graphics cards. It is also 80 PLUS Gold certified, with up to 90% efficiency under typical loads, and holds a Cybenetics certification for lower audible noise and reduced thermal output compared to non-rated units. Cooling is handled by a 140mm fluid dynamic bearing fan with Zero RPM mode support. Below a certain load threshold the fan stops spinning entirely, making the PSU effectively silent during light workloads such as browsing, media playback, or light gaming. Under sustained heavy loads the fan spins up quietly to maintain safe operating temperatures. Internally, the unit uses 100% Japanese-brand primary electrolytic capacitors rated to 105°C, which contribute to long-term reliability under sustained high-load operation. Cables connect via CORSAIR Type 5 Gen 1 micro-fit connectors, ensuring a secure latch and compatibility with CORSAIR's Type 5 cable ecosystem. Case compatibility requires an ATX PSU form-factor enclosure that is at least 210 mm (8.3 inches) wide internally, and side access to the PSU must be unobstructed once mounted.
