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
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.
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.

my computer speed is very slow why?
Micro ATX is one of the offshoots of ATX. The main difference from the main ATX form factor is size. ATX is a rectangular board size that measures 305mm. by 244mm. Micro ATX is a square that retains the 244mm. width but cuts down the length to by 61mm.
The Main difference between a Switched Mode Power Supply and an Uninteruptable Power Supply is the function. SMPS are like a conditioner of electricity supply for a building, house, etc. UPS are the emergency backup power supply for vital computer based systems
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.
ATX technology is related to the SMPS in which when the user shutdowns the PC, there will be power supplied to the motherboard until the mains are removed. Thus ATX technology helps in remote start up of PC whereas this is not possible with AT technology where the power is totally not supplied to the motherboard when PC is in shutdown state
NLX has slots parallel to the motherboard as ATX does not
ATX and BTX are types of motherboards designed by Intel. ATX is the more popular motherboard and has been around since the mid 90's and was designed for the ease of adding and removing components. BTX boards are newer then ATX and were designed to provide better airflow throughout the computer while maintaining the benefits of the ATX design. BTX has improved air flow , can be used in all cases and is able to use ATX power supply.
