hi i want to know my old mobo had 4 pin power connector but my new mobo has 8 pin connector what is the use of another 4 pin connector for what reason extra 4 pin comes for, one says for extra onboard vga, and i want to know what is the voltage of extra 4 pin is it 12v, and is that 8 pin full 24 volts

Both 4-pin and 8-pin connectors provide 12 volts. You need the 8-pin connector only if your CPU draws a lot of power, but you didn't provide any info about your motherboard and CPU. Most systems are fine with a 4-pin CPU connector from the PSU.

My mobo is gigabyte H86
But one said some gaming board has more than 12 volts then it should be 24 volts

That's impossible for that motherboard; it has to be some custom motherboard. An ATX PSU doesn't have a 24 volts rail. That person may have meant that some motherboards have a Molex connector that can be used if several high power GPUs are installed, but that probably isn't possible with your motherboard. I can't find a Gigabyte motherboard based on the H86 chipset.
