Ports
Dell OptiPlex 3080M provides a fixed set of external I/O ports for connecting peripherals and displays. Port availability and versions determine supported data transfer speeds and display capabilities.
USB ports
Dell OptiPlex 3080M includes six USB ports in total in the following configuration - (4x) USB-A 3.0; (2x) USB-A 2.0; with no USB 3.1 ports available.
Video ports
Dell OptiPlex 3080M features one DisplayPort 1.4 output, suitable for modern digital displays.
HDMI output is provided via one HDMI 1.4 port.
Motherboard video outputs require a CPU with integrated graphics. Systems equipped with a dedicated GPU must use the video ports on the graphics card instead.
SSD storage - M.2 sockets and SATA ports
The Dell OptiPlex 3080M comes with one SATA port(s) for connecting storage devices.
Dell OptiPlex 3080M has also one M.2 socket(s) that supports PCIe NVMe (PCIe 3.0 x4) or SATA M.2 drives with speed of up to 4 GB/s. This configuration works very well for both gaming and work related tasks.
The M.2 PCIe SSD connector in combination with an NVMe drive allows for higher transfer rates, compared to the old SATA interface. In some situations, NVMe device connected to the M.2 PCIe socket can be more than 5 times faster.
*Keep in mind that some M.2 connectors may not support SATA SSDs. Check the motherboard manual to confirm compatibility.
