AMD's Ryzen AI 9 HX 370 mini PC drives three displays at once: HDMI 2.1 and DisplayPort 1.4 both do 4K@120Hz, and the single rear USB-C adds a third via DisplayPort 1.4 Alt Mode. That USB-C port is USB4 at 40Gbps, not Thunderbolt — Beelink's own spec sheet stamps it "TBT3", which only means it accepts existing Thunderbolt 3 peripherals, not that it carries Intel certification. Networking is a single 2.5G RJ-45, and power arrives from a 100W external 19V brick rather than over USB-C.

Notes & Compatibility
AMD Ryzen AI 9 HX 370 (12C/24T, Zen 5, 65W TDP) mini PC. NAMING CAVEAT: Beelink’s storefront now titles this same HX 370 hardware “SER9 Pro”, while other SER9 Pro SKUs ship a slower Ryzen 7 255/265 — check the CPU, not the name. The rear USB-C is USB4 40Gbps with PD and DisplayPort 1.4 Alt Mode; Beelink’s “TBT3” label denotes Thunderbolt 3 peripheral compatibility (standard USB4 behaviour on AMD), NOT Thunderbolt certification, and the USB4 port’s PD wattage is not published. Sources also list an additional 3.5mm audio jack on the rear panel, but its type (line-out vs combo) is not confirmed by Beelink or by reviewers, so it is left unmodeled here — only the front headset jack is listed below. Powered by an external 19V/5.26A (~100W) DC brick with a barrel inlet, not modeled. Maximum three simultaneous displays (HDMI + DP + USB4). No OCuLink, SFP+ or eSATA.
