Boy, ya got me.
If it was a small square opaque white socket on the motherboard, that a power cable from the Power Supply; had two YELLOW wires, and two Black wires, and plugged into it, I would know what it is,
http://www.playtool.com/pages/psuconnectors/connectors.html#atx12v4As technology for personal computers advanced, hardware components needed more power.
The motherboard wasn't able to deliver the power needed, so the 4-pin ATX +12 Volt power cable, was brought out.
More power was needed later.
Hardware components demanded more power, than a 4-pin ATX +12 Volt power cable could deliver.
So the 8-pin EPS +12 Volt power cable was brought out,
http://www.playtool.com/pages/psuconnectors/connectors.html#eps8It CONNECTS to the motherboard. (For motherboards that use one)
NOT to be confused with the 8-pin PCI Express power cable,
http://www.playtool.com/pages/psuconnectors/connectors.html#pciexpress8This power cable plugs into a GRAPHICS CARD, not the motherboard. Note the color code of the wires.
For a PCI Express expansion slot on the motherboard, for a graphics card; the best the PCI Express slot can deliver is 75 Watts.
The 6-pin PCI Express power cable was brought out next,
http://www.playtool.com/pages/psuconnectors/connectors.html#pciexpress
It is plugged into the graphics card too, and can deliver up to an additional 75 Watts.
Now there is 150 Watts available for the graphics card.
Computer technology advanced, and the 6-pin PCI Express power cable, couldn't deliver the power needed.
Now comes the 8-pin EPS +12 Volt power cable.
The 8-pin EPS +12 Volt power cable by itself, can deliver up to an additional 150 Watts.
Now there is 225 Watts available for a graphics card.
75 Watts from the motherboard, 150 Watts from the 8-pin EPS +12 Volt power cable.
Color code of wires;
1) Orange = 3.3 Volts
2) Red = 5 Volts
3) Yellow = 12 Volts
ALL are DC Voltage
(Two flashlight batteries produce 3 Volts DC)
4) Black wires are Ground wires. Also are known as Negative wires.
This motherboard happen to have a manufacturer name, and Model Number?
Can't find it?
How about the computer manufacturer name, and model number, it came out of?
The model number for a desktop computer, is on the back of the computer, next to the Windows product key; or up on the side of the computer tower.
(The plastic front of a desktop computer is the Front Panel.
Some older computers had a Door in the Front Panel.
The door is opened, and you look inside -> Down, for the model number)
