What is 6 pin or 8 pin power connector ?

[Aler]

I'm considering to upgrade my PC
I will probably buy a GTX 750 Ti (which can require a power connector or not)
And I will buy a new PSU

My questions
1)Are these 6 pin or 8 pin power connectors come along with PSU or they MUST be on the motherboard to attach the GPU ?
2) up to 75Wno additional PCIe power required, what does this mean ? Does it mean that this card does not require 6 pin(or smthing else) power connector ?

They come with the PSU. Any modern PSU will have at least two GPU power connectors. 6 or 8 pin is handled by adapters. Usually the same cable.

EDIT: Just to be on the safe side. Post the PSU you intend to buy.

1 they come attached to the psu not the mobo 2 it means that the gpu will get all the power from the pcie socket and will not need any extra power so a 6/8 pin is not needed

Thank you
So there is no requirement that motherboard should have these kind of stuff except PCIe2 x16 slots ?

Make sure it has a 80+ rating at the least

80+ rating is related to performance right ?
Gold silver etc ?

Seems good but don't think I can find this one
I'm gonna buy and make the seller put them(in PC) together at the same place since I don't really know how to place them etc. :D
