Recommended DDR5 RAM Upgrades:
- Corsair Vengeance DDR5 SO-DIMM — Premium DDR5 laptop memory with excellent compatibility.
- Kingston Fury Impact DDR5 SO-DIMM — High-performance DDR5 with solid heat dissipation.
- Crucial DDR5 SO-DIMM — Budget-friendly DDR5 with proven stability.
Storage Expansion
The ThinkPad P16s Gen 3 uses a standard M.2 2280 NVMe SSD with a NVMe PCIe Gen4 interface. With 2 M.2 slots, you can run dual NVMe drives for expanded storage.
Recommended M.2 2280 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 ThinkPad P16s Gen 3 charges over USB-C, using a 100W or 135W Lenovo slim adapter (USB Power Delivery 3.0). There is no 230W barrel unit for this machine.
It is a 16-inch workstation, so the wattage matters: a 65W USB-C charger will run it at idle but will not keep up with the CPU and RTX 500 Ada GPU under load. Use a 100W adapter as the minimum, 135W if your configuration shipped with one.
Port & Docking Capabilities
Connectivity: 2x Thunderbolt, 2x USB 3.2, 1x HDMI, SD slot
The Thunderbolt ports enable high-speed data transfer and external GPU support. A Thunderbolt dock like the CalDigit TS3 Plus provides multi-display support.
Upgrade Difficulty & Tools Required
The ThinkPad P16s Gen 3 has a difficulty rating of 3/5 for upgrades (5 = easiest). The upgrade process is moderate — requires careful handling of bottom panel clips.
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.
