The G14 (2025) AMD 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)

M.2 NVMe SSD solid state drive

The G14 (2025) AMD 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 (2025) ships with a 200W adapter using a proprietary rectangular connector, not USB-C. ASUS supports 100W USB-C PD as a secondary, travel-weight option; it is not sufficient under load.

The memory is LPDDR5X soldered to the board with a 32GB ceiling, so there is no RAM upgrade path on this machine — specify the capacity you need at purchase.


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 (2025) AMD 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.
