Source Types
When we opened the cabinet of the PC, we can find two types of sources: AT or ATX (AT eXtended).
AT The source has three types of output connectors. The first type, of which there are two, are fueling the motherboard. The other two types, of which there is a variable quantity, feed the peripherals is plugged into a motherboard slotde, such as hard drives, units CD-ROM, floppy, etc.La motherboard connection is via two 6-pin connectors each of which must be plugged so that the two black wires are attached in the center.

The ATX is very similar to the AT, but has a number of differences, both in performance and in voltages delivered to the motherboard. ATX source actually consists of two parts: a primary source, which corresponds to the old AT power (with some additions), and an assistant.
FEATURES
AT power supplies were used until it appeared the Pentium MMX is at the time when would begin to use ATX power supplies.
features of AT sources, is that your motherboard connectors vary from those used in ATX sources, and are more dangerous, since the power is activated through a switch, and in that switch is a voltage of 220V, with risk that would manipulate the PC.
The AT are somewhat rudimentary electronically speaking, when compared with ATXLa technologically ATX, always active, even when the computer is not running, is always powered by a small strain in a state of espera.Las ATX sources have a button connected to the motherboard, and this is responsible for turning on the source, this allows us to make connections / disconnections software. In Fuentes AT, the problem was that there were two connectors to connect to motherboard thus could lead to confusion and shorts, the solution to this is based on a simple trick, leave the center black cables have two connectors, so there is no possible way wrong.

DIFFERENCES IN SOURCES PC
The main difference in performance is noted in the switch, instead of connecting and disconnecting the power supply 220VAC, as does the source of AT, it sends a signal to the main source, indicating that turns on or off, the assistant is always on and always connected 220VAC power, making possible to make connections / disconnections software.
There are three basic differences between the sources of AT and ATX power
• Has an extra-voltage line, that of +3.3 v
· The ATX power supplies have only a 20-way connector • Has
wire "power on", the source is turned off by software
ATX CONNECTOR
CONNECTOR AT
ADVANTAGES AND DISADVANTAGES
One advantage is that the sources ATX does not have a switch that turns on / off source, if it is a button connected to the motherboard, and this is responsible for turning on the source, this means for the power connections / disconnections software.
