Dead On Arrival (DOA)
pcDOA describes a condition where a hardware component is found non-functional at the point of installation or first use.
expanded
The term Dead On Arrival (DOA) is used in the context of computer hardware and technical equipment to refer to a unit that is defective or non-operational upon delivery. This situation is significant because it impacts initial setup and functioning, leading to potential delays and additional costs in returning or replacing the product.
examples
A desktop power supply unit is DOA if it shows no voltage output when connected to a power grid that meets the unit's specification of 230 V (50 Hz).
Commonly encountered during the assembly of custom PCs where components are sourced individually, the power supply must be tested immediately to ensure proper system boot.
A graphics card is considered DOA if it fails to display any output when tested on a standard PCIe x16 slot of a motherboard that supports PCIe 3.0, indicating incompatibility or defect.
Frequently addressed in professional settings such as gaming PC assembly and workstation deployments, where initial testing on installation is critical.
