Looking for a 7-pin adapter

[Ubrousek]

Hello,

6 years ago I bought 

The name of PC

HP Pavilion Gaming Desktop 690-0015nc

Now I am looking for an upgrade, but because it is a pre-build PC I have some troubles.

I found out, that 

Motherboard

Lincs

My motherboard has a 7-pin connector to my ATX1.

Otherwise it is all good.

Can you recommend me an official/not official way how to buy or found 7-pin adapter to motherboard ATX1? I have not found the adapter or your official store and also on others.

Thank you.

I found the spec for your motherboard here

you will need to use Firefox as the link is HTTP not HTTPS

There is an upgrade video here

I do not know of what 7 pin connector you are referring to, sorry.

Hello, Beemer Biker.

I might see the problem now. I was not that specific. The "7-pin cable" is a cable from supply power unit to the ATX1.

So I lately figure out after seing HP motherboard specification, that it could be a SATA cable.

Corect me if I am wrong please. 

Thanks for the YT upgrade video too. I didnt write it, but I  upgrade a supply power unit. The card trick seems cool.

Back to my first question:

Can I buy  the adapter on HP store or should I look for somewhere else?

Can you also link me a supply power unit specification? Or just write me If it is a SATA cable please.

Thank you for fixing kind of a "dumb 7-pin question" by linking a motherboard specification.

SATA pinouts

To add a  disk drive you may need a splitter if there are not enough power connectors 

any of these will work for data
