The ATX power supply and AT power supply had different connections for the computer motherboard. Also the ATX power supply had provision for some parts of the power supply to be switched on-and-off by the electronics on the motherboard, possibly under the control of software. With an AT power supply it necessary for the user to physically operate a switch. This control feature means that a computer that has an ATX power supply can provide, for example, a "wake-on-LAN" or "wake-on-modem" feature whereby the computer will switch itself on if their a signal on the ethernet cable or modem cable. If necessary it should be possible to adapt an ATX power supply to replace an AT power supply. This could be done by finding an adapter cable. The mother board cable from the ATX power supply would then plug into the adapter cable and the adapter cable would plug into the motherboard.

Difference between at and atx SMPS?
At smps have only 20 pin power connector atx have 20 + 4 pin power connectors atx smps 24 + 4 pin power connectors at (advanced technology)is old model smps atx (advanced technology extended) is new model
Can a AT SMPS be replaced by ATX SMPS?
Ya easily. just take the ATX smps and pull out it's two extra pin from it's power plug and set it to the PC.
How many pins does ATX SMPS have?
24
Deferents between AT smps and ATX smps?
Basic difference between these are :- AT means "Advance Technology" while ATX is used for "Advance Technology Extended" SMPS. With respect to AT SMPS, ATX has an extra Plug of +12v Supply for Motherboard. It has four wires connected in square size plug. Two of them are Yellow and other two are black.
What is the purpose of SMPS?
An SMPS is a switched-mode power supply. It is used to convert an unregulated power input into a regulated power output, often altering the voltage. In a modern computer, several components may be powered from the same power supply but will often require different regulated voltages. The SMPS fulfils this role.
Why smps is called so?
It has the options to switch between 2 voltages .
What is the full form atx smps?
Advanced Technology Extended Switched Mode Power Supply
Is smps is a input device or output?
Its a processing device..
What are the voltages for a ATX power supply?
the ATX standard supplies three positive rails: +3.3 V, +5 V, and +12 V
How many output terminals in smps?
smps out voltage is 12volt.. A switch mode power supply can have an output voltage of any value. However, common values are 5, 12 and 24V.
What are the five voltages that can be produced by ATX or BTX?
12V, 8V, 5V, 3.3V, and 2V.
What are the 5 voltages produced by and ATX power supply?
+12V, -12V, +5V, -5V, +3.3V
