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.
SMPS [Switch Mode Power Supply ] also known as PSU [Power Supply Unit] is used in desktops to convert AC TO DC and to divide voltage to appropriate units to different components.... Since Laptops has a adapter [which does the job] which comes with the charger a seperate smps is not needed........ or Its included in the package..to be more clear yes laptops need smps
normally the power button :)
Which of the following holds the system date and time
Computers work on DC supplies and convert AC to DC supply through SMPS (fixed in cabinet). Specifications of SMPS decides the load a Computer can handle.
smps
by shorting the red and green pin of smps we can check it working or not
Connect Pin No. 14 & 15 on SMPS, if the fan moves then SMPS is working fine else SMPS is faulty.
To cool the SMPS while the computer is working.
HI This Is Adil, We can check it out in different ways.. but i know only two ways... 1. while strating up the system press the "num lock KEY" check wether its running or not then .. if its not working then its shows that SMPS is not working. 2. By removing all the connections from the motherboard and by keeping the copperwire on the 13th and 14th block (or) green and black coloured blocks, keep the wire in it if fan is running then the smps is in good condition... keep one night with out power and then use it...
smps means switch mode power supply
SMPS are mainly 4: flyback pushpull halfbridge full bridge
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.
motherboard problem, other wise change smps then turn on computer if it is boot-up smps problem. that's problem occur in smps or motherbordAnswermotherboard problem, other wise change smps then turn on computer if it is boot-up smps problem. that's problem occur in smps or motherbord
SMPS stands for switched mode power supply
There are various ways to troubleshoot smps of PC. SMPS stands for switching mode power supply. You can start by trying if it works elsewhere and if this the case, then it means that your motherboard is faulty.
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
