HP 870-090 Omen Gaming Desktop

HP 870-090 Omen Gaming Deskto

Hi, I would like to know what my  options for internal expansion are? How many additional hard drives does this desktop  support? Just from looking at the pics, I noticed some extra space which 1 presume was for an additional drive. I would love to know how many and what type of free slots are available? Also, are there power and sata connections available for expansion? I saw some pics and review here.

The specs does not show us spare bay(s) (or mounting places) on its chasis


But looking at its size I think you can add one more HDD (curently 3 bays are occupied by 256GB SSD, 2TB HDD and ODD). Its motherboard also have few spare SATA ports

My suggestion: open the case to confirm PHYSICAL room. You may need mounting kit to be able to install new HDD for example (you need single one only):

Another option for you is to install a NVMe m.2 SSD.  The motherboard image posted by Banhien shows a 2280 form factor slot (socket 3, M key). If you go with this option then consider the Samsung 960 EVO NVMe SSD that is at least 256 GB but preferably 512 GB or larger,


I suggest that you update the diagnostics first and then the BIOS update (2B4B) before installing the NVMe m.2 SSD.


Take a image of the Disk Manager display that shows the partitions for both of your existing SSD and HD devices and post the image to the forum before attempting to install the NVMe m.2 SSD.
