Setup and Installation
1. Preparation
- Ensure your computer case supports ATX power supplies and has adequate space for the SAMA XPH-1000A.
- Gather necessary tools: Phillips head screwdriver.
- Unpack the power supply and all accessories.
2. Installation Steps
- Mounting the Power Supply:
Carefully slide the power supply into the designated PSU bay in your computer case. Ensure the fan faces the correct direction (usually downwards for bottom-mounted PSUs, or according to case design for optimal airflow).

Secure the power supply to the case using the provided mounting screws. Typically, four screws are used at the rear of the case.
- Connecting Cables:
Identify the necessary cables for your components:
- 24-pin ATX Mainboard Cable: Connect to the motherboard's main power connector.
- 4+4 pin CPU (EPS) Cable: Connect to the CPU power connector on the motherboard. Some motherboards may require two such connectors.
- 12VHPWR Cable: For PCIe 5.0 graphics cards. Connect one end to the PSU's 12VHPWR port and the other to your graphics card.
- 6+2 pin PCIe Cables: For older or additional graphics cards. Connect to the PSU's PCIe ports and your graphics card(s).
- SATA Power Cables: For SATA hard drives, SSDs, and optical drives.
- IDE/Molex Power Cables: For older peripherals or case fans.
Connect only the cables required for your system to minimize cable clutter and improve airflow.
- Cable Management:
Route cables neatly to ensure proper airflow within the case. Use cable ties or Velcro straps if available.
- Final Connection:
Once all internal components are connected, connect the AC power cord to the power supply's inlet and then to a wall outlet or surge protector.
Operating Instructions
1. Powering On
- Ensure the power switch on the back of the power supply is in the 'O' (Off) position before connecting the AC power cord.
- Connect the AC power cord to the power supply and a grounded wall outlet.
- Flip the power switch on the power supply to the 'I' (On) position.
- Press the power button on your computer case to start the system.
2. Intelligent Fan Controller (IFC)
The SAMA XPH-1000A features an Intelligent Fan Controller. The 120mm fan will automatically adjust its speed (0-1600 RPM) based on the internal temperature of the power supply. At low loads and temperatures, the fan may stop completely for silent operation. This is normal and indicates efficient thermal management.
3. Powering Off
- Shut down your computer operating system normally.
- Once the system is off, you may flip the power switch on the power supply to the 'O' (Off) position for complete power disconnection.
Maintenance
The Inter-Tech SAMA XPH-1000A Power Supply is designed for reliable, long-term operation with minimal maintenance. However, periodic cleaning can help ensure optimal performance and longevity.
- Dust Removal: Periodically (e.g., every 6-12 months), disconnect the power supply from the AC outlet and use compressed air to gently blow dust out of the fan grill and ventilation openings. Do not open the power supply casing.
- Cable Inspection: Occasionally check all connected cables for secure connections and signs of wear or damage.
- Environment: Ensure the power supply operates in a clean, dry, and well-ventilated environment.
