Computer ATX Casing is good than AT

AT casing is not using at present to assemble a computer. Therefore, I am narrating about ATX casing. ATX casing is using a lot of computer than AT casing. ATX casing has two raw where has ten cable connectors in one raw. Total two raw has twenty-cable connector. For these connectors, the ATX casings are very favorable and using a lot of computer. So, I am describing about power supply of ATX casing’s cables with color in below table.

PIN	COLOR	FUNCTION	PIN	COLOR	FUNCTION
1	Color	+3.3 VDC	11	Orange	+3.3 VDC
2	Orange	+3.3 VDC	12	Blue	-12 VDC
3	Black	Common	13	Black	Common
4	Red	+5 VCD	14	Green	Power Supply On
5	Black	Common	15	Black	Common
6	Red	+5 VDC	16	Black	Common
7	Black	Common	17	Black	Common
8	Grey	Power Good	18	White	-5 VCD
9	Purple	-5 VCD	19	Red	+5 VCD
10	Yellow	+12 VCD	20	Red	+5 VCD

As these casings, have many bays. Each bay are being used to set Hard Disk, Optical Driver, Floppy Driver etc. basically in Desktop casing has five bays, Mini Tower casing has seven bays and Tower Casing has ten bays.

At last, I want to tell you that present’s casings are very powerful and reliable. So no need to tension about casing. Only need to tell to shopkeeper that you want a good, reliable and a designable casing which electrically strong and powerful.
