>> FAQ
Q1: Can I install a standard discrete desktop graphics card on this board?
A: Yes, the QM8900 motherboard includes a full-sized PCI-E x16 expansion slot for external graphics cards. Please note that when a discrete GPU is activated, the onboard display outputs (HDMI, VGA, EDP) will automatically be bypassed.
Q2: Does the onboard M.2 Key-M slot support SATA-protocol M.2 SSDs?
A: No, the M.2 Key-M slot on this Coffee Lake platform exclusively supports High-Speed NVMe (PCIe) protocol SSDs (2280/2242 sizes). If you require SATA storage, you can utilize the onboard MSATA slot or the standard SATA 3.0 port.
Q3: What power adapter capacity is recommended for the QM8900 motherboard?
A: The board features flexible 12V or 19V DC power input via either a standard 5.5*2.5mm DC jack or an internal 4-pin ATX header. While the base motherboard power consumption is around 70W, we recommend using a 12V/7A or 19V/5A (or higher) power adapter to ensure stable performance under heavy processing loads.
