- Floppy: P15 (Floppy) connector.
- HCI (Human Computer Interface): P16 (HCI) connector for power consumption management.
Protection: Includes comprehensive protection mechanisms: OVP (Over Voltage Protection), OCP (Over Current Protection), OTP (Over Temperature Protection), OLP (Over Load Protection), and Short Circuit Protection.
Power Factor Correction: Active Power Factor Correction (PF > 0.99) ensures efficient power usage.
Installation: The manual provides a step-by-step guide for installation, including connecting the power supply to the motherboard and peripheral devices, and installing the 3.5” Human Computer Interface into the chassis.

Maintenance Features:

Troubleshooting: A dedicated section guides users through common issues if the system fails to turn on after installation, emphasizing checking power switch status and connector connections. It also notes that the power supply does not support -5V for new ATX form factor motherboards and advises updating BIOS settings if necessary.
Safety Safeguards:
- Always turn off and unplug the PSU from the AC outlet before cleaning.
- Use a dry cloth for cleaning; avoid liquid or aerosol cleaners.
- Do not install or operate the computer system near water.
- Ensure the PSU is powered by the source indicated on its rating label.
- Never spill liquids on the PSU.
- Contact the service center if the PSU does not operate normally.
Warranty: Cooler Master provides a three-year hardware limited warranty for the power supply from the date of purchase, contingent on normal use. The warranty is voided by abuse, alteration, misuse, negligence, incorrect voltage supply, air/water pollution, accidents, or natural disasters. The product is designed for computer usage only; use in other applications voids the warranty. Professional assistance is recommended for installation if the user is unfamiliar with computer hardware.
