Memory Upgrade Path
The G14 (2026) has soldered LPDDR5X RAM which cannot be upgraded after purchase. Select the maximum RAM configuration when buying.
Important: Since the RAM is not user-replaceable, we recommend opting for at least 16GB at purchase to ensure adequate performance for years to come.
Storage Expansion (M.2 NVMe)
The G14 (2026) uses a standard M.2 NVMe SSD with a NVMe PCIe 4.0 interface. The single M.2 slot supports drives up to 2TB.
Recommended M.2 SSDs:
- Samsung 990 Pro NVMe 2280 — Flagship NVMe SSD with exceptional speeds.
- WD Black SN850X 2280 — High-performance NVMe with excellent sustained writes.
- Crucial P5 Plus NVMe 2280 — Excellent value NVMe with strong real-world performance.
Power Delivery & Charging
The Zephyrus G14 (2026) ships with a 200W proprietary barrel adapter. ASUS also supports 100W USB-C PD charging as a travel option, but that is not enough to sustain the machine under gaming load — it will charge slowly and throttle.
Note that the G14 has never been offered with an Intel processor. The 2026 GA403 is an AMD Ryzen AI 9 465 machine, and its USB-C ports are USB4 rather than Thunderbolt.
Port & Docking Capabilities
Connectivity: Thunderbolt 4, USB 3.2
The Thunderbolt 4 ports provide fast external storage and high-bandwidth peripherals. Consider a Thunderbolt dock like the CalDigit TS4 or Belkin Thunderbolt 4 Dock Pro for desktop expansion with multiple displays and storage.
Upgrade Difficulty & Tools Required
The G14 (2026) has a difficulty rating of 5/5 for upgrades (5 = easiest). The upgrade process is very easy.
Tools needed:
- Phillips screwdriver (M2.5 or similar)
- Plastic spudger or pry tool (for bottom panel clips)
- ESD wrist strap (optional but recommended)
We recommend backing up your data and consulting the official service manual before opening the chassis.
