Cable Connections:
The MWE Gold V2 PSU comes with a variety of modular cables. Ensure you use the correct cables for each component:
- ATX 24-pin: Connects to the motherboard.
- EPS/ATX 12V 8-pin (4+4 pin): Connects to the CPU power socket on the motherboard.
- PCIe 6+2 pin: Connects to graphics cards.
- SATA Power: Connects to SATA drives (HDDs, SSDs) and other SATA-powered devices.
- Peripheral (Molex) 4-pin: Connects to older devices or case fans.
Note: Always refer to your motherboard and component manuals for specific connection requirements.
Troubleshooting
Issue: PSU does not power on.
- Ensure the AC power cord is securely connected to both the PSU and a working wall outlet.
- Verify that the power switch on the back of the PSU is in the 'ON' position (I).
- Check that all internal power connections to the motherboard and components are secure.
- Try a different wall outlet or power cord.
Issue: System is unstable or shuts down unexpectedly.
- Ensure the PSU's wattage capacity is sufficient for your system's components.
- Check for loose power connections.
- Monitor system temperatures; overheating may cause shutdowns.
- Test with minimal components connected to isolate the issue.
Issue: Loud fan noise.
- The fan may be operating at a higher speed due to high system temperatures. Ensure adequate airflow within the case.
- If the noise persists at low loads, there might be an issue with the fan. Contact Cooler Master support.
Maintenance
To ensure optimal performance and longevity of your MWE Gold V2 PSU:
- Periodically clean dust from the PSU's air intake and fan using compressed air. Ensure the unit is unplugged from the AC outlet before cleaning.
- Avoid placing the PC in enclosed spaces that restrict airflow to the PSU.
