Assistance With Part?

Hello

I i have a hp 590-p0054 and i was hoping someone here knows what this piece of plastic is referenced as so i can buy it

The manufacturer doesn't make it simple to search these parts on their store or manuals because well they dont't have them listed ( probably because model is barely a year old)...

Anyways i was trying to take off the cable and i accidentally ripped off the black piece i pictured
this. The black plastic piece has 8 pins , and is no longer there so only the 8 pins are sticking out

I would like to buy the piece and glue it on to the motherboard

Also this computers power supply had no sata connectors! Instead it had this odd really cable i never seen before which looks like an 8 pin molex connector to sata. I also need this cable but i can't find any info on it online or even find it.. The cable itself connected to the slim dvd drive and an internal hard drive.

 

i managed to find the part number for the cable

L17725-001 no one has it though.. why in the hell would they use this type of cable ..

Cable has blue, red lime green colors and 2 black ( sata cables running) and a thin one that appears to be 7 pins ( for a dvd drive)

i attached a better picture of the other port
As i mentioned on my first post the black part came off the pins are all exposed
I just need to know what the black plastic piece is called so i can glue one to the motherboard

 

It looks like an 8-pin 12V power connector.
