Unit Overview and Dimensions

This document details the technical specifications and physical layout of the FSP 9PA8503600 power supply unit (PSU), model FSP850-50ADB. The unit is designed with specific dimensions, including a length of 150.00 mm, a width of 86.00 mm, and a height of 75.00 mm. The PSU features a perforated metal casing for ventilation, indicated by a grid pattern in the drawings. Key connection interfaces are labeled for Motherboard (MB), Graphics Processing Unit (GPU), Central Processing Unit (CPU), Peripheral devices, and PCI-Express (PCI-E) slots. A designated area for a 'SPEC LABEL' is also shown.

Notes:

All output wire lengths exclude the housing.
Dimensional tolerances are specified as: .XX = ±0.5 [0.02] and .XXX = ±0.25 [0.01].

Cable Connections and Routing

The internal components of the system connect to the power supply unit via various cables, identified by connector reference IDs P1 through P33. These cables are routed to specific interfaces on the motherboard (MB), graphics cards (GPU), CPU power connectors, peripheral devices, and PCI-E power connectors. The document illustrates the typical routing paths and specifies cable types and lengths. Common cable treatments include three-strand black braided mesh and approximately 50mm of black heat shrink tubing (applied twice). Cable lengths are provided with tolerances, such as 650±15mm, 500±15mm, and 100±10mm.

Connector Pinout Details

The following table provides a comprehensive pinout configuration for the power supply connectors. It details the connector reference ID, pin number, signal name, wire color, wire gauge, and the type of connector used, including specific model numbers where available.
