ASROCK Power Supply Steel Legend Sl-1000gw 1000w 80+ Gold White ATX

Native PCIe 12V-2x6 cable with a dual color design and ASRock Classic Green connectors allows easy visual confirmation of proper connection. The Steel Legend series power supplies are available in 1000W, 850W, 750W and 650W capacities in Steel Black and Steel White finishes. These PSUs combine 80 PLUS Gold efficiency with Cybenetics Platinum & Gold ratings and LAMBDA A+/A acoustic certification for low-noise, energy-efficient operation. Key hardware features include a 135 mm fluid dynamic bearing fan and high-temperature Japanese capacitors for long service life. ASRock includes comprehensive protection circuitry and a 10-year warranty.

Advantages

The ASRock Steel Legend power supply provides high energy efficiency and certified low-noise performance, reducing power losses and operating sound. The iCOOL intelligent fan control offers two modes: an automatic low-noise mode that keeps the fan off under light to medium loads and a continuous mode for constant cooling under heavy loads. Durable Japanese capacitors and a fluid dynamic bearing fan extend component lifespan. Visual dual-color PCIe connectors simplify installation checks, and a full set of safety protections with a 10-year warranty ensures long-term reliability.

How to use

Install the power supply into your PC case according to the case and PSU manual, ensuring the orientation allows airflow to the 135 mm fan. Connect the native PCIe 12V-2x6 cable to your compatible motherboard or device and verify visual engagement using the dual-color ASRock Classic Green connector. Choose iCOOL Mode ON for quieter operation during normal desktop use or iCOOL Mode OFF when continuous fan operation is preferred for sustained heavy loads. Observe standard safety practices: power off and unplug the system before making or changing connections.

Recommendations

Use a model with wattage appropriate to your system’s total power draw, leave enough clearance for airflow around the 135 mm fan, and enable iCOOL Mode ON for quieter daily use unless sustained heavy workloads demand constant cooling.
