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.
Note: The 12V-2×6 connector features a dual-color housing design on both sides. Ensure the blue part is fully inserted for a secure connection.
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. This smart cable management design not only enables clean and efficient cable routing but also frees up valuable space inside the case, resulting in a tidier and more professional-looking build.
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.

TRIPLE PCIe 6+2 pin GPU SUPPORT
The RB 750W goes further with an extra 100mm 12V 2×6 to PCIe 6+2 pin cable, delivering a total of three 8-pin connectors for high-end AMD GPUs. This added flexibility makes it a future-proof choice for demanding users.
HIGH-QUALITY 105°C CAPACITORS
Built with premium 105°C capacitors, a robust single +12V high-amperage rail, and reliable DC-to-DC architecture, this PSU delivers stable and consistent power output. These high-quality components form the foundation of stability—reducing voltage fluctuations and noise to ensure smooth performance, extended component lifespan, and dependable reliability even under continuous operation at up to 40°C.
QUIET COOLING, STABLE OPERATION
Equipped with a 135mm HYB smart temperature-controlled fan, larger than the standard 120mm, the PSU delivers superior cooling performance even at lower fan speeds. This design not only improves heat dissipation but also helps reduce noise levels, ensuring efficient, quiet cooling for everyday tasks and stable operation under heavy workloads.
