Smart Routing, Cleaner Builds

CLASSIC BLACK × THREE WATTAGE OPTIONS

Available in classic sleek black, the RB Series offers 750W, 650W, and 550W options to suit everything from everyday PCs to high-performance systems.

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. 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.

RELIABLE EFFICIENCY, EVERYDAY SAVINGS
Certified 80 PLUS Bronze, the RB Series offers up to 85% energy conversion efficiency. It reduces heat and power consumption, making it an ideal and economical solution for everyday systems.

ENHANCED DURABILITY WITH FULL PROTECTION
Built to operate at up to 40°C, the RB Series features six industrial-grade protections: OVP, UVP, OCP, OPP, OTP, and SCP, ensuring stable power delivery even under harsh conditions.

CERTIFIED SAFETY & PROTECTIONS
The RB Series is backed by international safety certifications, including CE, FCC, TUV, BSMI, and CB, ensuring reliable protections and consistent performance.
