Know before you buy
Yes, the RM1200e includes a dedicated PCIe 5.0 12VHPWR cable, allowing you to connect modern high-performance graphics cards directly without needing adapters.
Being fully modular means every cable can be detached from the power supply. You only plug in the cables your specific components require, which significantly reduces clutter and improves airflow inside your case.
The RM1200e features a compact 150mm depth, which is shorter than many other 1200W units. This smaller footprint provides extra clearance for cable management in tighter chassis configurations.
Yes, it features a Zero RPM fan mode that keeps the fan completely off during low to medium loads for silent operation. When the load increases, the 140mm rifle bearing fan engages to maintain optimal temperatures.
ATX 3.0 compliance ensures the power supply can handle the sudden, high-power spikes common in modern graphics cards and processors. It provides better stability and reliability for high-end hardware.
