Fonte de alimentação ASROCK SL-1000G Steel Legend 1000 W 20+4-Pin ATX 80 PLUS Gold preto

ASROCK SL-1000G Steel Legend is an ATX power supply unit delivering 1000 W of continuous output with 80 PLUS Gold efficiency. Designed for desktop and high-performance builds, it comes in black and includes a 20+4 pin ATX motherboard connector, a 135 mm fluid dynamic bearing fan for active cooling, and modular cable options. Built-in protections guard against overheat, overcurrent, overload, overvoltage and short circuit. The unit also features a native 12V-2x6 PCIe cable with dual-color connectors for clear insertion indication, iCOOL intelligent fan control, and high-quality Japanese capacitors rated for 105 °C for long-term reliability.

Advantages

The power supply combines high energy efficiency with low acoustic signature thanks to 80 PLUS Gold certification and Cybenetics Lambda A+ noise rating. iCOOL intelligent fan control allows the fan to remain off at low-to-medium loads for quieter operation and improved efficiency, while continuous fan mode can be selected for consistent cooling under heavy loads. A 135 mm fluid dynamic bearing fan and high-temperature Japanese capacitors increase lifespan and stabilize voltages under sustained load. Dual-color ASRock connectors simplify correct cable installation, and an extensive protection suite helps protect connected components.

Suitable for

• High-performance gaming PCs and workstations requiring 1000 W supply capacity
• Systems where low noise operation is important (home office, streaming rigs)
• Custom builds using modular cables and modern PCIe power connectors
• Upgrades for ATX systems needing stable power and strong protections

How to use

Install the ASROCK SL-1000G into a compatible ATX case following standard PSU mounting procedures and connect the 20+4 pin ATX plug to the motherboard. Use the modular cables to connect CPU, GPU and peripheral power lines as required, matching the dual-color PCIe connectors for correct orientation. Choose iCOOL mode ON for quieter, more efficient operation at low to medium loads or iCOOL mode OFF for continuous fan operation during heavy workloads. Ensure sufficient case airflow and route cables to avoid obstructing the fan intake.

Recommendations

To maximize lifespan and stability, operate the power supply within its rated load and maintain good case ventilation. For quiet environments enable iCOOL mode and monitor temperatures under sustained high loads. Use the native 12V-2x6 PCIe connectors for modern GPUs and verify connector seating using the dual-color indicators. Replace filters and clean dust from the fan and vents periodically to preserve cooling performance.
