    • Ensure the power supply is unplugged from mains power before continuing. If the device is powered on during disassembly, serious harm or death may occur.

    • The entire power supply can be taken apart with a Phillips screwdriver and adjustable wrench.

    • Removing the eight cover screws on either side of the power supply allows the cover to lift off

    • Screws can be organized using an iFixit Magnetic Project Mat

    • A fuse protects the system from overcurrent conditions and the chassis is grounded to protect the user from shorts to the case.

  3. RadioShack 22-510 Switching Power Supply Teardown, Remove Fan: 步骤 3 中的图像 1,3 RadioShack 22-510 Switching Power Supply Teardown, Remove Fan: 步骤 3 中的图像 2,3 RadioShack 22-510 Switching Power Supply Teardown, Remove Fan: 步骤 3 中的图像 3,3
    • The fan connector pulls out by hand. The spade terminal connectors may require coaxing with a pair of pliers.

    • The Sunon MagLev KDE1205PFV2 runs at 4300 RPM for a maximum airflow of 13 CFM. A dirty fan might not meet these specifications. Remember to clean your fans!

    • The illuminated switch is connected by two sets of black and white AC wires and held in by two locking tabs.

    • The switch is hooked up to the primary side of the circuit. If the switch faults while energized, it has potential to shock the user.

    • The board lifts out of the chassis after removing the five screws holding it down.

    • The capacitors may still be charged, do not touch the terminals! The capacitors can be discharged by shorting the terminals with an insulated screwdriver.

    • The UC3842BN PWM controller handles the switching feedback.

    • The chassis has a sheet of plastic for short circuit prevention under the board.

    • A thermally conductive pad lies under the heatsink assembly for additional cooling capability.

    • Organized parts make reassembly a breeze.
