Add a third HD to my Pavilion p7-1247c

Pavilion p7-1247c
Microsoft Windows 10 (64-bit)

I just added an SSHD to this system.  Discovered that I could not add it as a third drive, because found the bay only accomdated two drives.  I think that the case is tall enough for a third drive.   And I see an empty SATA port on the motherboard, tho I don't know for sure if it will support a HD.



  1. Can I add another HD to this motherboard?
  2. If so, where can I get a taller drive bay compatible with this case?

Thanks much for any help.

Welcome to HP Forums,

Thank you for posting your query, I'll be more than glad to help you out 🙂


I see that you're wanting to know information on Adding 3rd hard disk on HP Pavilion p7-1247c Desktop,

NOTE: HP does not recommend upgrading or downgrading hardware parts or software that is bundled with the product as It may affect the manufacturer's warranty and performance, however, you could change the configuration at your own discretion.


When adding a hard drive, it is important to identify the connectors on the motherboard.

The hard drive connectors on the motherboard must match the type of hard drive you wish to connect. If your motherboard has SATA data connectors and one is not in use, you can attach an additional SATA hard drive. If your motherboard has an IDE connector available, you can attach an IDE hard drive.
