• MB 24-pin: Connect to the motherboard's main power connector.
• EPS (CPU): Connect to the motherboard's CPU power connector(s).
• PCIe: Connect to graphics cards requiring 6-pin or 8-pin PCIe power.
• 12V-2x6: Connect to PCIe Gen5 graphics cards requiring the 12V-2x6 (12+4 pin) connector. This connector is crucial for modern high-performance GPUs.
• SATA/Peripheral: Connect to SATA devices (SSDs, HDDs, optical drives) and other peripherals.

Important: Only use SilverStone MC5 modular cables with this power supply.

5.4 Initial Power-Up

1. After all internal connections are made, connect the AC power cord to the power supply's inlet and then to a wall outlet.
2. Ensure the main power switch on the power supply's rear panel is in the 'ON' position.
3. Power on your computer system.

6. Operating Instructions

6.1 Semi-Fanless Operation (ECO Mode)

The SilverStone DA850R Gold features a semi-fanless mode, controlled by the 'ECO' switch on the rear panel. When 'ECO' mode is enabled (switch in 'ON' position), the fan will remain off during low to moderate loads to minimize noise. The fan will automatically activate when the power supply load or internal temperature exceeds a certain threshold, ensuring optimal cooling. When 'ECO' mode is disabled (switch in 'OFF' position), the fan will operate continuously.

7. Maintenance

To ensure the longevity and optimal performance of your power supply, follow these maintenance guidelines:

• Cleaning: Periodically clean the exterior of the power supply and its fan grille using a soft, dry cloth. For internal cleaning (e.g., dust removal from fan blades), use compressed air. Ensure the power supply is completely disconnected from AC power before cleaning.
• Ventilation: Ensure that the power supply's intake and exhaust vents are not obstructed. Good airflow is crucial for efficient cooling.
• Cable Management: Proper cable management within your PC case can improve airflow and reduce dust accumulation.

8. Troubleshooting

If you encounter issues with your power supply, refer to the following common troubleshooting steps:

• No Power:
  • Check if the AC power cord is securely connected to both the power supply and the wall outlet.
  • Ensure the main power switch on the power supply's rear panel is in the 'ON' position.
  • Verify that all modular cables are correctly and firmly connected to both the power supply and the components.
  • Test the wall outlet with another device to confirm it has power.
• System Instability/Random Shutdowns:
  • Ensure your system's power requirements do not exceed the power supply's capacity.
  • Check for proper ventilation and ensure the power supply is not overheating.
  • Verify all power connections are secure.
• Fan Not Spinning (in ECO mode):
  • This is normal behavior for semi-fanless operation under low loads. The fan will activate automatically when needed.
  • If the fan never spins even under heavy load, try disabling ECO mode to force continuous fan operation. If it still doesn't spin, contact support.

If problems persist after following these steps, please contact SilverStone customer support or your retailer.
