Internal SATA adapter DELOCK 90890 — PCIe to 5× SATA (JMicron JMB585), low profile, black

DELOCK 90890 is an internal SATA adapter card that adds five internal SATA ports to a desktop system via a PCIe x4 host interface. The card is based on the JMicron JMB585 chipset and is supplied as a low-profile, black PCI Express expansion card suitable for compact cases. It enables connection of SATA storage devices such as 3.5" and 2.5" hard drives, SATA SSDs and optical drives for storage expansion or controller-based setups and is compatible with common operating systems including Windows 10/11 and Linux with Kernel 6.5.

Advantages

The adapter provides five additional internal SATA connectors while occupying a single PCIe x4 slot, allowing flexible expansion of storage capacity without replacing the motherboard. Its low-profile form factor supports installation in small form-factor chassis and the JMicron JMB585 chipset offers standard SATA features including S.M.A.R.T. and TRIM support for SSDs. The card’s black finish and compact design simplify integration into existing systems, and driver support for modern Windows and Linux kernels reduces setup complexity.

How to use

Install the DELOCK 90890 into an available PCIe x4 or larger slot on the motherboard, secure the card to the case using the appropriate bracket, and connect power to each SATA drive using the system’s power supply cables. Attach SATA data cables from the card’s internal SATA connectors to each drive. After hardware installation, power on the system and install drivers if the operating system does not automatically recognize the JMicron JMB585 chipset. Configure drives in the OS storage management utility or RAID software as required.

Recommendations

Ensure your power supply has sufficient SATA power connectors and capacity for the number and type of drives you plan to attach. Use quality SATA cables and verify the case has mounting space for the drives. For RAID setups or critical data storage, follow OS or software vendor guidance for initialization, monitoring and backups; enable S.M.A.R.T. monitoring and TRIM for SSDs where supported.
