there is two versions of same mothrboard available ....what is the difference ?

GA-B75M-D3H (rev. 1.0)

GA-B75M-D3H (rev. 1.1)

when i looked the specs , everything is same in both motherboard except the cpu power supply header ... rev 1.0 has 4 pin header and rev 1.1 has 8 pin header and other things are mostly same

if almost everything in specs are same , then what does it mean by revision ?

these are the pictures of both versions

You already got the difference. It is the header. That's why it's not a different model, but only a different revision.

Basically the same board, but could be small differences or improvement, like not the same provider for certain components like capacitors and such, etc... Or new types of connectors as you already observed yourself.

its just an improvement on the same board so no need for a different model number.

Revisions are just slight changes to a board.

In your case, 8 pin cpu, the memory is a bit closer and the pci-e slot has a different lock from what I can see.

All the boards functions should be the same(you may be able to push a cpu farther with the extra power from the 8-pin cpu power, but with the rather basic power system, It may not be any better.).

Some boards have revisions with newer PCI-E switches(to support 3.0 on boards that only supported 2.0 at release.) for SLI/Xfire.

does it mean the revised board is better than older one ?

and i my psu is this http://www.flipkart.com/corsair-cmpsu-430cxv2uk-430-wat...

it has only 8 pin( 8 pins are attached together . can't separate 4 out of 8 i guess ) cpu mobo connector but the revision 1.0 mother board has only 4 pin header .. can i connect them both ?

if yes how ?
