ASUS ROG 1200W Platinum PSU

This ASUS ROG power supply delivers 1200W of continuous power for high-end desktop systems. It carries 80 PLUS Platinum certification for high energy efficiency. The unit targets enthusiasts building workstations or multi-GPU rigs. It is sold new and ready for immediate installation.

1200W capacity and Platinum headroom

The 1200W rating provides substantial headroom for power-hungry components under full load. Platinum efficiency reduces waste heat and lowers running costs during sustained operation. The unit handles peak demands from modern graphics cards and overclocked CPUs. It runs out of capacity only in extreme multi-GPU configurations exceeding its rated output.

ATX fit and modular freedom

Standard ATX dimensions allow the PSU to fit most full-tower and mid-tower chassis. Fully modular cabling lets builders connect only the cables required for their specific hardware. This reduces internal clutter and improves airflow through the case. The design frees up space for custom loops or additional storage drives.
