Next-Gen Power for PCIe 5.1 Systems

The ASRock SL-1000GW/UK is engineered for the latest high-performance GPUs, supporting PCIe 5.1 with its native 12V-2×6 connector. This ensures stable, clean power delivery to the most power-hungry graphics cards, preventing voltage drops and system instability during intensive workloads or gaming sessions.

Fully Modular Design for Clean Builds

With fully modular cables, you can connect only the wires you need, reducing clutter inside your case. This improves airflow, makes cable management easier, and gives your build a cleaner, more professional appearance. The white finish also complements modern PC aesthetics.

Ultra-Quiet Operation with Smart Cooling

Equipped with a 135mm striped fan and iCool mode, this PSU automatically adjusts fan speed based on system load. Under light use, the fan stays silent, while under heavy load it ramps up efficiently to maintain optimal temperatures without excessive noise.

Premium Components for Reliability

Built with 100% Japanese capacitors, the SL-1000GW/UK offers exceptional reliability and longevity. These high-quality components ensure stable voltage output and reduce the risk of power-related hardware failures over time.
