Atx power supply specification

The −V supply was primarily used to provide the negative supply voltage for RS-2ports and is also used . Compared with ATX Power Supply. It includes supplementary information not . Important Information and Disclaimers updated. This document outlines a reference ATX power supply that complies with the ATX.

It is intended to provide additional power supply design information not detailed in the ATX 2. Specification , Version 2. Readers should examine their combination of motherboar power supply , and chassis needs to determine whether they require the additional features found in Version 2. Section - Updated Figure to . C ontact your local Intel sales office or your distributor to obtain the latest specifications and before placing your product order. T his doc ument c ontains. Design Guide for Desktop Platform Form Factors. Added Flex ATX power supply form factor.

The ATX standard allows power supplies and cases to be commodity parts, dramatically reducing the cost of computer design. Lessons learned from the success of this standard show why standardizing parts is important. The BTX standard builds on this, and the blade. Power supplies have several specifications that define their input and output capabilities as well as their operational characteristics.

This section defines and examines most of the common specifications related to power supplies. ATX and the standards that have followed since use different connectors with additional voltages and signals that allow systems with greater power consumption and additional. Just as with the mechanical shape of the power supply , these connectors are usually designed to conform to one of several industry-standard specifications , which dictate the types of connectors used as well as the pinouts of the individual wires and terminals. Unfortunately, just as with the mechanical form . Over the years, the base components of computer systems have dramatically changed.

In order to standardize the design of the system, specifications standards were developed for desktop computers that define the various dimensions, layouts and electrical requirements so that parts could be . In addition to the old AT standar ATX 2. ATX specification includes not only Power Supply Unit, but also interface to case and motherboard. V), a connector chain-lined to the single 20-pin and a power-on wire that allows Software to turn off the PSU. Several units (on hand) show . Older systems use non-12V ATX or SFX power supplies.

For armature hobbyist, they will hack the computer desktop power supply. Yup, it is actually a switching power supply dedicated for computer motherboard. You can buy it from computer shop, I am pretty sure they have it on rack. We are going to utilize it as the power source for our project and .
