Key Specs

Next-Gen GPU Ready with PCIe 5.1

The RM750e includes a native 12V-2×6 PCIe 5.1 cable, delivering up to 600 W of GPU power. This makes it fully compatible with the latest NVIDIA RTX 40-series and AMD RX 7000-series graphics cards, ensuring clean, stable delivery for high-end gaming and rendering workloads.

ATX 3.1 Certified for Future-Proof Reliability

Meeting the ATX 3.1 standard, this PSU handles extreme transient loads from modern GPUs and CPUs. Its robust LLC resonant topology with DC-DC conversion maintains steady voltage under stress, reducing the risk of system crashes or instability during heavy gaming or content creation sessions.

Low-Noise Operation in a Compact Design

A 120 mm rifle-bearing fan with a specially tuned curve keeps noise to a minimum, even at full load. The compact 140 mm depth fits easily into most mid-tower cases, making cable routing and airflow management simpler without sacrificing cooling performance.

Fully Modular for Cleaner Builds

Only connect the cables you need. The fully modular design reduces clutter inside your case, improves airflow, and makes upgrades or maintenance easier. With multiple PCIe and SATA connectors, it supports both current and future expansion without excess wiring.
