About this tag
The power supply cables tag on WindowsForum.com covers the connectors that link a PSU to PC components, with discussion grounded in real build and troubleshooting questions. The tagged content examines why CPU power leads split into 4+4 pin halves, tracing the design back to the Pentium 4 era and Intel's ATX and EPS12V specifications, and compares those connectors with 6+2 PCIe leads used for graphics cards. It suits readers checking compatibility before a build, upgrading a motherboard, or working out which cable belongs where. The focus stays on practical PC hardware rather than Windows software, so expect connector pinouts, specification history, and safe cabling advice.
