A Power Supply is a direct replacement for the original part, which supplies power to other components in your Dell™ system. This product has been designed to convert general-purpose alternating current electric power to usable low-voltage direct current power for the internal components. It is supported by Dell Technical Support when used with a Dell™ system.

Please use the Service Tag Lookup feature in the Parts For Your Dell tool. This will allow us to identify your PC’s power limits and chassis requirements and make recommendations.

Please note that some of our replacement products are provided as kits or assemblies. These kits may contain additional parts required for installation.

In case a product is not sold as a kit or assembly, it may require complementary parts for ease of installation.

Refurbished Spare Parts are parts retrieved from Dell-branded systems that have been returned, some of which have never been used. All Dell refurbished spare parts are certified to comply with all original Dell factory performance specifications and come with a 90-day limited hardware warranty.
