Inter-Tech SL-500K (500W) ATX PSU

Inter-Tech SL-500K is a basic 500W ATX power supply aimed at budget configurations and office machines, where high-end hardware and heavy overclocking are not pursued. It operates in the range of 200–240VAC and offers a standard set of connectors for older and newer devices. It does not have an 80+ certification or RGB effects, making it a clean and pragmatic option if you simply want a machine that gets the job done. The case is in silver color, so it visually stands classic, especially in older or office cases.

What you get is a compact ATX power supply with a length of only 140 mm, which facilitates installation in tighter cases. With one fan and Passive PFC circuitry, the power supply is oriented towards basic stability, without unnecessary extras. The configuration of 3 x SATA and 2 x Molex / IDE connectors allows you to connect several HDD/SSD, an optical drive, or older hardware like fan controllers and older peripherals. The main 20+4 Pin connector and ATX 12V 4-Pin are mainly suitable for motherboards without heavy CPU requirements. The output lines DC 3.3/5/±12 V cover the classic needs of a standard system without powerful GPU cards.

• Power 500W – sufficient for office configurations, lighter home PCs, and systems without power-hungry graphics cards.
• ATX format (140 x 150 x 86 mm) – standard size that fits easily into most mid-tower and older cases.
• Power supply 200–240VAC – optimized for the network voltage in Europe, suitable for everyday use at home or in the office.
• 1 x 20+4 Pin + 1 x ATX 12V 4-Pin – basic connectivity for standard motherboards without extreme CPU configurations.
• 3 x SATA connectors – allows you to connect several SSD/HDD or an optical drive without running out of ports.
• 2 x Molex / IDE + 1 x Floppy 4-Pin – convenience if you have older devices or additional fans and controllers.
• Passive PFC – basic power factor correction, without complex active electronics.

This power supply is suitable if you are building a budget or office computer, an older home PC, or simply looking for a replacement for an old PSU of a similar class. It fits well for systems without claims for high-end gaming, without heavy GPUs, and without the need for a high energy class. If you plan a more serious gaming build with a powerful graphics card and high consumption, it is better to look for a higher class PSU with certification and a stronger line.

The most sensible thing about the Inter-Tech SL-500K is the combination of 500W power, standard ATX dimensions, and a full set of basic connectors, giving you a cheap and direct option for a simple, working configuration.
