5. Setup u Installazzjoni
Follow these steps to properly install your SilverStone SX500-LG power supply.
5.1. Preparazzjoni
- Unpack the power supply and all accessories.
- Kun żgur li s-sistema tal-kompjuter tiegħek hija mitfija kompletament u skonnettjata mis-sokit tal-ħajt.
- If replacing an existing PSU, carefully remove it from your system.
5.2. Immuntar tal-PSU
The SX500-LG is an SFX-L form factor PSU. It can be installed directly into SFX-L compatible cases or into ATX cases using the included ATX adapter bracket.
- For SFX-L Cases: Align the PSU with the mounting holes in your case and secure it with the provided screws.
- For ATX Cases: Attach the ATX adapter bracket to the SX500-LG, then mount the assembly into your ATX case's PSU bay using the appropriate screws.

5.3. Konnessjoni ta' Kejbils Modulari
Connect only the necessary cables to your components. The fully modular design allows for better cable management.
- Qabbad il-kejbil ATX ta' 24-pin mal-motherboard tiegħek.
- Connect the 4+4-pin EPS (CPU) cable to your motherboard's CPU power connector.
- For graphics cards, connect the 6+2-pin PCIe cables as required.
- Connect SATA power cables to your SSDs/HDDs and optical drives.
- Connect Peripheral (Molex) cables for any other components requiring them.
- Kun żgur li l-konnessjonijiet kollha huma siguri u mqiegħda sew.

6. Istruzzjonijiet Operattivi
6.1. Tixgħil / Mitfi
- After all connections are made, flip the power switch on the back of the PSU to the 'ON' (I) position.
- Press your computer's power button to start the system.
- To power off, shut down your operating system normally, then flip the PSU power switch to 'OFF' (0) if desired for complete power disconnection.
6.2. Semi-Fanless Operation
The SX500-LG features an intelligent semi-fanless operation. The 120mm fan will remain off under low load conditions to provide silent operation. As the system load and internal temperature increase, the fan will automatically spin up to dissipate heat. This design optimizes for quietness while ensuring adequate cooling when needed.

7. Manutenzjoni
Manutenzjoni xierqa tiżgura l-lonġevità u l-prestazzjoni ottimali tal-provvista tal-enerġija tiegħek.
- Żomm il-ventijiet ċari: Ensure that the intake and exhaust vents of the PSU are not obstructed to allow for proper airflow.
- Tindif tat-Trab: Periodically clean dust from the PSU's fan and vents using compressed air. Do this with the system powered off and unplugged.
- Żarmax: Never attempt to open the power supply unit. There are no user-serviceable parts inside, and doing so can be dangerous and will void your warranty.
8 Issolvi l-problemi
If you encounter issues with your SX500-LG, refer to the following common troubleshooting steps:
- Ebda Qawwa:
- Iċċekkja jekk il-korda tal-enerġija AC hijiex imqabbda sew kemm mal-PSU kif ukoll mas-sokit tal-ħajt.
- Kun żgur li s-swiċċ tal-enerġija fuq wara tal-PSU jkun fil-pożizzjoni 'ON' (I).
- Verify all modular cables are correctly and firmly connected to the PSU and your components.
- Ittestja s-sokit tal-ħajt b'apparat ieħor biex tikkonferma li għandu l-enerġija.
- Instabbiltà/Ħsarat tas-Sistema:
- Kun żgur li r-rekwiżiti tal-enerġija tas-sistema tiegħek ma jaqbżux il-kapaċità ta' 500W tal-PSU.
- Iċċekkja jekk hemmx ventilazzjoni xierqa fil-kaxxa tal-PC tiegħek biex tevita li tissaħħan iżżejjed.
- Verify all components are correctly installed and seated.
- Ħsejjes mhux tas-soltu:
- The SX500-LG operates in a semi-fanless mode; the fan may not spin at low loads. This is normal.
- If the fan is spinning and making excessive noise, ensure no cables or obstructions are interfering with the fan blades.
- If a persistent, abnormal noise (e.g., grinding, high-pitched whine) occurs, contact SilverStone support.
If problems persist after following these steps, contact SilverStone customer support for further assistance.
