Model :
SKU : PS-SILVERSTO ATTIS 650R B
Compliant with ATX 3.1 standards and supports up to 2X power excursion
High efficiency with 80 PLUS Bronze certification
24/7 continuous power output with 50℃ operating temperature
Japanese primary capacitor
Silent running 120mm fan with 18 dBA minimum
Multiple protection circuitry

Performance / Technology
The hallmark of a quality power supply is its internal protection circuitry. The ATTIS 650R is loaded with industrial-grade safeguards, including Over Power Protection (OPP), Over Voltage Protection (OVP), Short Circuit Protection (SCP), and Under Voltage Protection (UVP). If your local power grid surges or a component fails, the PSU will instantly sacrifice itself to prevent the electrical fault from destroying your motherboard and processor.
Design & Deployment Strategy
Featuring a stealthy Black Edition exterior, this non-modular power supply easily blends into the dark interior of modern tempered-glass chassis. Cable Management Tip: Because the cables are fixed, it is highly recommended to build inside a PC case that features a dedicated basement (PSU shroud). This allows you to easily tuck away any unused SATA or peripheral cables, maintaining a clean, professional aesthetic while promoting unobstructed airflow to your graphics card.
Why This Product Stands Out
The SilverStone ATTIS 650R stands out by democratizing the ATX 3.1 standard. It allows budget-conscious PC builders to access the critical power excursion safety features previously locked behind expensive, high-wattage Gold and Platinum tier units, making it the smartest choice for a mid-range system.
