4. Configurazione e installazione
Follow these steps to install your ASRock STEEL LEGEND 1000W Power Supply:
- Prepara il tuo sistema: Assicurati che il computer sia completamente spento e scollegato dalla presa a muro. Apri il case del computer.
- Rimuovere il vecchio alimentatore (se applicabile): Scollegare tutti i cavi dal vecchio alimentatore e rimuoverlo dal case.
- Montare il nuovo alimentatore: Carefully place the ASRock STEEL LEGEND 1000W into the PSU mounting bay of your computer case. Secure it with the provided screws. Ensure the fan is facing the correct direction for optimal airflow (usually facing down if there's a bottom vent, or up if not).
- Connect Modular Cables to PSU: Identify the necessary cables for your components (motherboard, CPU, graphics card(s), SATA devices, etc.). Connect these cables to the corresponding modular ports on the power supply. Refer to the diagram below for port identification.

Figure 4.1: Modular Cable Connection Panel
- Connect Cables to Components:
- Scheda madre: Connect the 20+4 pin ATX cable to your motherboard.
- PROCESSORE: Connect the 4+4 pin EPS CPU cable(s) to your motherboard's CPU power connector(s).
- Graphics Card(s): Connect the 6+2 pin PCIe cable(s) or the 12+4 pin PCIe 5.1 cable to your graphics card(s). Ensure you use the correct connector type for your specific GPU.
- Dispositivi di archiviazione: Collega i cavi di alimentazione SATA ai tuoi SSD, HDD e unità ottiche.
- Periferiche: Connect Molex cables to any other peripherals requiring this type of power.
- Gestione dei cavi: Route cables neatly to improve airflow and aesthetics. The flat cables provided are designed to assist with this.
- Controllo finale: Controllare attentamente tutti i collegamenti per accertarsi che siano saldamente fissati.
5. Istruzioni per l'uso
Once the power supply is installed and all components are connected:
- Collegare l'alimentazione CA: Plug the AC power cord into the power supply's inlet and then into a wall outlet.
- Power On the PSU: Locate the main power switch on the rear of the power supply and flip it to the 'ON' (I) position.

Figure 5.1: Rear Panel with Power Switch and iCOOL Switch
- Start Your Computer: Premere il pulsante di accensione sul case del computer.
iCOOL Mode
The ASRock STEEL LEGEND 1000W features an iCOOL MODE switch on the rear panel. This mode allows the fan speed to automatically adjust based on the power supply's temperature and load. When activated, the fan operates almost silently at low loads and increases speed for effective cooling under high loads. To enable or disable iCOOL MODE, toggle the switch next to the main power switch (refer to Figure 5.1).
6. Manutenzione
- Pulizia: Periodically clean the exterior of the power supply and its fan grille to prevent dust buildup. Use a soft, dry cloth or compressed air. Ensure the power supply is turned off and unplugged before cleaning.
- Flusso d'aria: Ensure that the power supply's intake and exhaust vents are not obstructed. Good airflow is crucial for efficient cooling and longevity.
- Non smontare: Never attempt to open the power supply unit. High voltages are present inside, even when unplugged, and doing so will void your warranty.
7. Risoluzione Dei Problemi
Se riscontri problemi con l'alimentatore, prova a seguire questi passaggi:
- Nessun potere:
- Verificare che il cavo di alimentazione CA sia collegato saldamente sia all'alimentatore che alla presa a muro.
- Ensure the main power switch on the PSU's rear panel is in the 'ON' (I) position.
- Verificare che la presa a muro funzioni collegandovi un altro dispositivo.
- Check all modular cable connections to ensure they are firmly seated in both the PSU and the components.
- Il sistema si spegne inaspettatamente:
- The power supply's built-in protection mechanisms (OCP, OVP, OTP, OPP, UVP, SCP) may have activated due to an overload, overvoltage, overheating, or short circuit.
- Ensure your system's power consumption does not exceed the PSU's capacity.
- Check for proper ventilation around the PSU and inside the case to prevent overheating.
- Disconnect non-essential peripherals to see if the issue persists.
- Fan Not Spinning (iCOOL Mode): If iCOOL Mode is enabled, the fan may not spin at low loads to maintain silent operation. This is normal. The fan will activate as the load and temperature increase. If the fan never spins even under heavy load, ensure iCOOL Mode is enabled or try disabling it to force the fan on.
If problems persist after performing these checks, contact ASRock customer support or your retailer for assistance.
