Product information

Description

The Inter-Tech SL-500 Plus 500 W is a desktop power supply unit designed for standard ATX systems. It delivers up to 500 W total power with an efficiency of at least 82%, accepts 230 V AC input at 50–60 Hz and uses a 120 mm active cooling fan to maintain stable temperatures while operating at a low noise level of approximately 25 dB. The unit is supplied in a silver finish and includes PCI Express and CPU power cables to simplify installation.

Advantages

The SL-500 Plus offers reliable 500 W output and 82% efficiency, which helps reduce wasted energy and operating costs. A 120 mm fan provides effective cooling with low audible noise. Multiple connector types — including a 20+4 pin ATX motherboard connector, 4+4 pin CPU, PCIe 6+2 pin, four SATA and three Molex connectors — give flexibility for configuring both older and newer PC components. The compact design and standard connectors make it compatible with a wide range of systems.

Suitable for

  • Home and office desktop PCs with standard ATX cases
  • Upgrading older systems that require Molex or SATA power
  • Basic gaming or multimedia builds that need up to 500 W

How to use

Install the power supply in a compatible ATX case, secure it with screws and connect the 20+4 pin ATX cable to the motherboard. Attach the 4+4 pin CPU connector to the CPU power header and use the 6+2 pin PCIe connector for compatible graphics cards. Connect SATA and Molex connectors to drives and peripherals as needed. Ensure the input voltage is set to 230 V AC and that the system remains well ventilated to allow the 120 mm fan to cool the unit effectively.

Usage recommendations

For stable operation, pair the SL-500 Plus with systems that have moderate power demands and avoid overloading the supply beyond its 500 W rating. Regularly check cable connections and maintain case airflow to preserve efficiency and reduce noise.
