Features

  • COMPACT SIZE FOR HIGH COMPATIBILITY

    With a compact 150mm depth, the RB Series fits easily into most ATX cases, making it a great choice for space-conscious or minimalist builds without compromising on power.

  • BUILT FOR THE LATEST ATX 3.1 STANDARD

    Fully compliant with the latest ATX 3.1 standard, this PSU supports next-gen hardware demands with native 12V-2×6 PCIe connectors for improved safety and power delivery. Engineered to handle high transient loads with greater efficiency, it’s ready for the most demanding GPUs and future upgrades.

  • SMART CABLE MANAGEMENT

    The RB Series features a built-in deep routing channel and Velcro straps on three sides of the PSU housing to keep cables securely in place. Excess cables can be easily tucked away, while thick CPU and GPU power lines stay neatly organized. This improves airflow, reduces clutter, and results in a cleaner and more professional build.

  • UNIQUE THREE-SIDED CABLE ROUTING AND BUNDLING

    Designed to perfectly accommodate back connectors and compact cases, the RB Series features key cables such as the CPU (4+4 pin), main power (20+4 pin), and SATA/peripheral connectors neatly secured with Velcro straps on three sides of the PSU housing.

  • MODULAR FOR PERIPHERALS

    To maintain a clutter-free build, modular SATA and peripheral cables let users connect only what they need. These cables are neatly routed through a dedicated grooved channel and secured with built-in Velcro straps on the PSU housing, improving airflow and maintaining a clean, professional look.
