The 2025 ROG Zephyrus G16 (GU605) pairs Intel Core Ultra 200-series HX silicon with an NVIDIA RTX 50-series laptop GPU inside a 16-inch OLED chassis. Video I/O is anchored by a Thunderbolt 4 USB-C port on the left that delivers 40 Gbps data, DisplayPort output and up to 100 W of charging, plus a second USB-C 3.2 Gen 2 port on the right that also carries DisplayPort and 100 W PD for opposite-side docking. A full-size HDMI 2.1 FRL jack supports 4K@120 Hz to an external display, and a UHS-II SD card reader handles camera workflows. Wall power uses a proprietary 240 W DC barrel connector — the USB-C ports can keep the laptop running but not feed the discrete GPU at full tilt.
16″ OLED gaming laptop with Thunderbolt 4 and USB-C 3.2 Gen 2 (both 100 W PD, DP out), HDMI 2.1 FRL, and UHS-II SD.

Notes & Compatibility
Thunderbolt 4 USB-C is on the LEFT side (primary charging), USB-C 3.2 Gen 2 with DisplayPort 1.4 + 100 W PD is on the RIGHT side — both can charge the laptop but only the bundled 240 W proprietary DC barrel supplies full performance under heavy GPU load. HDMI 2.1 port is FRL (Fixed Rate Link) and supports 4K@120 Hz. UHS-II SD reader is a full-size SD slot, not microSD. Proprietary DC barrel power inlet omitted (not in approved connector database).
