4. Setup and Installation

Follow these steps to install your ASRock Steel Legend SL-1000P power supply:

1. Prepare Your System: Ensure your computer is completely powered off and unplugged from the wall outlet. Open your computer case to access the PSU mounting area.
2. Mount the Power Supply: Carefully place the SL-1000P into the designated power supply bay in your PC case. Secure it with the provided mounting screws. Ensure the fan is oriented correctly for optimal airflow (typically facing downwards if there's a bottom vent, or upwards if not).
3. Connect the Motherboard Cables:
   • Connect the 24-pin ATX motherboard cable to the corresponding port on your motherboard and the PSU.
   • Connect the 4+4-pin or 8-pin CPU power cable(s) to the CPU power connector(s) on your motherboard and the PSU.
4. Connect PCIe Cables (Graphics Cards):

   For graphics cards requiring PCIe power, connect the appropriate 6+2-pin PCIe cables from the PSU to your graphics card(s). For next-generation GPUs, utilize the native 12V-2x6 cable.

5. Connect SATA/PATA Cables: Connect SATA power cables to your storage drives (SSDs, HDDs) and optical drives. Use PATA cables for older peripherals if necessary.
6. Cable Management: Route cables neatly to improve airflow and aesthetics. Use the provided cable ties.
7. Final Check: Double-check all connections to ensure they are secure. Close your PC case.
8. Power On: Connect the AC power cable to the PSU and then to a wall outlet. Flip the power switch on the PSU to the "ON" position. You can now power on your computer.

Using the ATX 24-pin PSU Tester: The included PSU tester can be used to verify the power supply is functional before connecting it to your system. Connect the 24-pin ATX cable to the tester and the PSU, then plug in the AC power. If the fan spins, the PSU is generally functional. Do not connect any other cables to the PSU while using the tester.

5. Operating Instructions

The ASRock Steel Legend SL-1000P is designed for reliable and efficient operation. Once installed, it requires minimal user intervention.

• Power On/Off: Use the main power switch on the rear of the PSU to completely cut power to the unit. For daily use, power on/off your system via the operating system or case power button.
• Efficiency: The SL-1000P is 80 Plus Platinum certified, meaning it operates with high energy efficiency, reducing heat generation and power consumption.

• 5V BOOST Function: This feature ensures stable and enhanced voltage for 5V ARGB lighting ecosystems, providing consistent and flicker-free illumination for compatible components.

6. Maintenance

Proper maintenance ensures the longevity and optimal performance of your power supply.

• Dust Cleaning: Periodically clean dust from the power supply's fan and ventilation grilles. Use compressed air to gently blow dust out of the unit. Ensure the system is powered off and unplugged before cleaning.
• Cable Inspection: Regularly check all modular cable connections to ensure they are secure and free from damage.
• Environment: Maintain a clean, dry, and well-ventilated environment for your computer to prevent dust buildup and overheating.

7. Troubleshooting

If you encounter issues with your ASRock Steel Legend SL-1000P, refer to the following common troubleshooting steps:

• System Not Powering On:
  • Ensure the AC power cable is securely connected to both the PSU and the wall outlet.
  • Verify the main power switch on the PSU is in the "ON" position.
  • Check all internal power connections (24-pin ATX, CPU, PCIe) are firmly seated.
  • Test the PSU using the included 24-pin PSU tester to confirm it is functional.
  • Try a different wall outlet or power cable.
• System Instability/Crashes:
  • Ensure all power cables, especially to the motherboard and graphics card, are correctly and securely connected.
  • Verify that your system's power requirements do not exceed the PSU's 1000W capacity.
  • Check for proper ventilation within your PC case to prevent overheating.
• Fan Not Spinning:
  • The iCool intelligent fan control may keep the fan off at low loads for silent operation. The fan will spin up as the load and temperature increase.
  • If the fan never spins even under load, ensure no obstructions are blocking it. If the issue persists, contact support.
• Burning Smell or Smoke:

  Immediately disconnect power from the wall outlet. Do not attempt to power on the system again. Contact ASRock support immediately.
