This page provides a menu of power supplies commonly found in the PC market. Most of these power supplies are out of production and exact (same manufacturer, model, version) replacement is not possible. This usually presents an opportunity to upgrade to newer technology, more power, lower costs, and greater efficiency.

Note: Your OEM power supply may have 3 pin connector for motherboard control of power supply fan. All replacement power supplies control fan speed directly obviating the need for this connector.
