The CORSAIR RM1200x SHIFT is a fully modular ATX power supply that provides 1200W of total power. Its primary design feature is a side-mounted modular connection panel, which offers direct access for cable management in compatible chassis. This unit operates with an 80 PLUS Gold certified efficiency rating, indicating reduced energy waste and lower heat output during operation. The design is compliant with the ATX 3.0 standard, ensuring support for modern high-performance components.
For thermal management, the PSU incorporates a 140mm fan that utilizes a Zero RPM mode, ceasing fan rotation under low to medium loads to minimize noise. The fully modular cabling allows system builders to use only the required cables, which can contribute to less clutter and improved airflow within the case. The unit is built with components rated for operation up to 105°C and includes a suite of protection circuits to safeguard system hardware against electrical faults.
