5. Setup è Installazione
Follow these steps to properly install your SilverStone SX500-LG power supply.
5.1. Preparazione
- Disimballate l'alimentatore è tutti l'accessori.
- Assicuratevi chì u vostru sistema urdinatore sia cumpletamente spento è scollegatu da a presa murale.
- If replacing an existing PSU, carefully remove it from your system.
5.2. Muntà a 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. Connecting Modular Cables
Connect only the necessary cables to your components. The fully modular design allows for better cable management.
- Cunnette u cavu ATX à 24 pin à a vostra scheda madre.
- 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.
- Assicuratevi chì tutte e cunnessione sò assicurate è pusate bè.

6. Operating Instructions
6.1. Powering On / Off
- 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.
