4. Enstalasyon ak Enstalasyon
Proper installation is crucial for the performance and longevity of your power supply. Always ensure your system is powered off and unplugged from the wall outlet before installation.
4.1 Prekosyon sekirite
- Disconnect the AC power cord from the wall outlet before handling the PSU or any internal components.
- Asire w ke koneksyon atè a apwopriye pou anpeche egzeyat elektwostatik (ESD).
- Pa louvri PSU a casing. Gwo volimtages are present inside, even when unplugged.
4.2 Enstalasyon Fizik
- Mount the PSU into the designated power supply bay in your computer case. Ensure the fan is facing the correct direction for optimal airflow (usually facing down if there's a bottom vent, or up if it's a top-mounted PSU).

- Pouvwa SATA: Connect SATA power cables to your storage drives (SSDs, HDDs) and other SATA-powered devices.
- PATA Power (Molex): Connect PATA power cables to older peripherals or case fans if needed.
After connecting all necessary internal cables, connect the AC power cord to the PSU and then to a wall outlet.
5. Operasyon Enstriksyon
5.1 Limen/Etenyen
- Asire ke tout câbles yo byen konekte.
- Flip the main power switch on the back of the PSU to the 'I' (On) position.

5.2 iCool Intelligent Fan Control
The ASRock Steel Legend SL-850G features an iCool switch on the rear panel. This switch controls the fan's operation mode:
- iCool ON: The fan will remain off at low to medium loads for silent operation. It will activate automatically when the load or temperature increases.
- iCool OFF: The fan will operate continuously, regardless of the load or temperature. This provides maximum cooling but may result in higher noise levels.
Choose the mode that best suits your preference for noise and cooling performance.

6. Antretyen
Antretyen regilye ede asire lonjevite ak pèfòmans optimal ekipman pouvwa ou a.
- Netwayaj: Periodically clean the exterior of the PSU and its fan grille to prevent dust buildup. Use compressed air to gently clear dust from the fan blades and heatsinks. Ensure the system is powered off and unplugged before cleaning.
- Jesyon kab: Ensure cables are neatly routed and do not obstruct airflow within the case.
- Anviwònman: Operate the PSU in a well-ventilated area, away from excessive heat, humidity, and direct sunlight.
NAN. Depanaj
If you encounter issues with your power supply, try the following troubleshooting steps:
- Pa gen pouvwa:
- Tcheke si kòd kouran AC a byen konekte ak tou de PSU a ak priz miray la.
- Ensure the main power switch on the PSU is in the 'I' (On) position.
- Verifye si priz miray la ap fonksyone lè w branche yon lòt aparèy.
- Use the included 24-pin PSU tester to check if the PSU powers on independently.
- Enstabilite Sistèm/Arè O aza:
- Ensure all modular cables, especially the 12V-2x6 PCIe cable, are fully seated and properly connected.
- Check for any loose connections to the motherboard, CPU, or graphics card.
- Verify that your system's power requirements do not exceed the PSU's 850W capacity.
- Fan Not Spinning (iCool ON):
- If iCool mode is ON, the fan may not spin at low loads. This is normal operation.
- If the fan does not spin even under load, try switching iCool mode OFF to force continuous fan operation. If it still doesn't spin, contact support.
- Bwi ki pa nòmal:
- Asire w pa gen okenn fil elektrik ki bloke vantilatè a.
- If the noise persists and is not related to fan operation, contact support.
