Intel EXPI9301ct: counterfeit or not

Hi!

I need to buy a network card Intel EXPI9301CT and want to know how to distinguish original card from counterfeit.

I know that original card have the following:

1) RJ-45 within opened bus pins and orange tape over it

2) Transformer 'Delta'

3) YottaMark golographic mark (for cards produced since 2009 year)

BUT cards I have seen in the market are differ from original one:

1) RJ-45 pinout contained in the black box

2) Transormer 'Pulse'

3) No any YottaMarks

They looks like as one the ebay page: INTEL EXPI9301CT Gigabit CT Desktop PCI-e Network Adapter 82574L Chipset NIC | eBay

Please help me to know how to distinguish original Intel expi9301ct:

1) Is Intel uses 'Pulse' transformers on its network cards? Is it means that the card is counterfeit?

2) Is YottaMark should be on ALL Intel cards?

Thank you!
