4. 설정 및 설치
Follow these steps to install your ASRock STEEL LEGEND 1000W Power Supply:
- 시스템 준비: 컴퓨터의 전원이 완전히 꺼져 있고 벽면 콘센트에서 플러그가 뽑혀 있는지 확인하십시오. 컴퓨터 케이스를 여십시오.
- 기존 파워서플라이를 제거하십시오(해당되는 경우): 기존 전원 공급 장치의 모든 케이블을 분리하고 케이스에서 전원 공급 장치를 제거하십시오.
- 새 파워서플라이를 장착하세요: 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:
- 마더보드: Connect the 20+4 pin ATX cable to your motherboard.
- CPU: Connect the 4+4 pin EPS CPU cable(s) to your motherboard's CPU power connector(s).
- 그래픽 카드: 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.
- 저장 장치: SATA 전원 케이블을 SSD, HDD, 광학 드라이브에 연결합니다.
- 주변 장치: Connect Molex cables to any other peripherals requiring this type of power.
- 케이블 관리 : Route cables neatly to improve airflow and aesthetics. The flat cables provided are designed to assist with this.
- 최종 확인: 모든 연결 부분이 단단히 고정되었는지 다시 한번 확인하세요.
5. 사용 설명서
전원 공급 장치를 설치하고 모든 구성 요소를 연결하면 다음과 같습니다.
- AC 전원 연결: 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: 컴퓨터 케이스의 전원 버튼을 누르세요.
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. 유지관리
- 청소: 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.
- 공기 흐름: Ensure that the power supply's intake and exhaust vents are not obstructed. Good airflow is crucial for efficient cooling and longevity.
- 분해하지 마십시오: Never attempt to open the power supply unit. High voltages are present inside, even when unplugged, and doing so will void your warranty.
7. 문제 해결
If you encounter issues with your power supply, try the following steps:
- 전원 없음:
- AC 전원 코드가 전원 공급 장치와 벽면 콘센트에 제대로 꽂혀 있는지 확인하십시오.
- Ensure the main power switch on the PSU's rear panel is in the 'ON' (I) position.
- 다른 장치를 연결해 벽면 콘센트가 작동하는지 확인하세요.
- Check all modular cable connections to ensure they are firmly seated in both the PSU and the components.
- 시스템이 예기치 않게 종료되었습니다:
- 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.
