Reliable Power Delivery

High-quality electrolytic capacitors ensure consistent and stable performance – even at temperatures up to 40 °C. The result is high efficiency, certified with 80 PLUS Bronze (85% at 50% load).
Modern Semi-Modular Power Supply

Installation is straightforward: Essential cables such as the 24-pin ATX for the motherboard and CPU-EPS are permanently attached. A PCIe 6+2-pin powers your graphics card. SATA and peripheral cables can be added as needed via modular connectors – so you only use the cables you really need.
For better organisation, integrated Velcro straps on three sides of the PSU help you bundle excess cables – reducing clutter and improving airflow inside your case.
Modern Standard: ATX 3.1
The RB Series 550W meets the ATX 3.1 standard, ensuring modern protection and efficiency requirements as well as stable load performance – a solid, future-proof foundation for your PC.
Quiet & Efficient Cooling
- 135mm HDB fan (larger than standard 120mm)
- More airflow at lower RPM
- 33.2 dB(A) at 1,300 RPM
- Consistent temperatures even under load
The larger fan moves more air at lower speeds, keeping the PSU cool and pleasantly quiet – even during extended gaming sessions.
