Hi, Please check http://www.smps.us/20-to-24pin-atx.html for this. Read the last part. It might help. Regards, Thiyagarajan.
Mass Turnpike west to NY state thruway. North and then join the Northwy and cross border to Montreal. Follow sign for Hiway 20 west and connect to hiway 540 and then 40 west to Ottawa
The main advantage is that transistors use less power. A typical small vacuum tube uses about 1.8 watts to heat its cathode, plus 3-5 watts to supply the main current to the anode. By contrast a computer motherboard might take 10-20 watts to power several million transistors.
Common factors of 20 are; 1,2,4,5, and 20. 1x20=20, 2x10=20, 4x5=20, 5x4=20, 20x1+=20. If you have to show your work then just check mine.The factors of 20 are 1,2,4,5,10 and 20. For them to be common, they have to be compared to another set of factors.
The LCM is 20.
The LCM of 4 and 20 is 20
20- pin connector
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
There should be a large connector coming from the Power Supply unit. You may have a 20 pin or a 24 pin connector on your motherboard. Most power supplies come with a 20+4 pin connector which allows them to connect to both 20 and 24 pin mother bards.
24 pin connector is required to supply power to the motherboard.
ATX
The atx 12 connector is one of the motherboard power connectors and used for 12 volt power connect for cpu voltage regulator.
ATX Ver 1.0 has one 20 pin port ATX Ver 1.1 has one 20 pin port and a 4 pin port ATX Ver 2.0 has one 24 pin port and a 4 pin port
20 pin P1 connector.
If it as a 20 or 24 pin connector and a 4 pin connector then it is a ATX power supply.
the regular ATX has a 20 pin power connector, while the enhanced ATX power connector has 24 pin power connector.
There are two cables that connect to the floppy drive in a desktop computer.There is a four pin power cableThere is a ribbon cable that has a part twisted end (the twisted end connects to the floppy drive).
ATX version 2.2 allowed for 24-pin P1 connector, which is backward compatible with the 20-pin P1 connector.
