Processor Support

Does your computer have a dual- or quad-core processor, and does it feature a PCI or SATA Express data connector - or both? These are questions to consider before deciding on a PC power supply. Many power supplies list specific compatible processor types and even models for quick assessment. You may want to examine other types of power supplies, including power distribution units and power tips, to find the right fit.

Connector Type

Before deciding on a power supply, ensure it comes with the right connector to ensure fast, easy hookup and installation with an existing computer. Primarily important is the number of pins in the connector; for example, a 20- or 24-pin connector will only accept a compatible motherboard port. You may also want to consider the connector length to ensure compatibility with your workstation's cable-management system.
