The Acer Nitro 16 AN16 is a larger gaming machine built around AMD Ryzen 7/9 processors and NVIDIA RTX 4060/4070 graphics. Like its smaller sibling, it’s fully upgradeable: dual RAM slots, dual SSD slots, and a powerful 230W charger to support sustained gaming on a 16-inch platform.
RAM Compatibility & Upgrade Guide
The Nitro 16 AN16 features 2 DDR5 SO-DIMM slots supporting up to 32GB total (two 16GB modules at 5600MHz). Both slots are easily accessible from the bottom panel, making RAM upgrades straightforward even for beginners.
To upgrade: power down, remove the battery if removable, unscrew the bottom chassis, and locate the two vertical SO-DIMM slots. Push the retention clips outward, lift the existing module at 45 degrees, and insert your new DDR5 module, pressing down until the clips snap.
Recommended DDR5 modules for the Nitro 16 AN16:
- G.Skill Flare X5 — AMD-optimised DDR5 5600MHz, proven stability on Ryzen systems
- Corsair Vengeance RGB PRO — Gaming-grade 16GB DDR5 5600MHz, excellent thermal performance
- Kingston FURY Beast — 16GB DDR5 5600MHz, affordable and reliable
AMD Ryzen & DDR5 Optimisation
AMD Ryzen processors benefit significantly from faster DDR5 speeds. The Nitro 16 AN16 supports 5600MHz DDR5, which is the sweet spot for Ryzen 7/9 performance. Enable DOCP in BIOS (AMD’s equivalent to Intel XMP) for automatic tuning — this is safe and recommended.
SSD & Storage Compatibility
The Nitro 16 AN16 excels with 2 M.2 2280 NVMe slots, both supporting PCIe Gen 4. This dual-slot design allows you to maximise storage for large game libraries, video projects, or streaming setups.
Recommended M.2 2280 PCIe Gen 4 SSDs for the Nitro 16 AN16:
| Model | Capacity | Speed | Gaming Performance | Amazon UK Link |
|---|---|---|---|---|
| WD Black SN850X | 1TB / 2TB | 7,100 MB/s | Excellent — gaming-proven, fast load times | View on Amazon |
| Samsung 990 Pro | 1TB / 2TB | 7,100 MB/s | Premium option, excellent reliability | View on Amazon |
| Sabrent Rocket 4 Plus | 1TB / 2TB | 7,000 MB/s | Budget gaming alternative, solid build | View on Amazon |
| Kingston Fury Beast Pro | 1TB / 2TB | 7,100 MB/s | Gaming-optimised, affordable | View on Amazon |
How to install dual SSDs: Power down, remove the bottom panel, and locate both M.2 slots (typically labelled M.2_1 and M.2_2). Unscrew the single retention screw at 45 degrees on each slot, insert your new drives, and secure. You can install both simultaneously — there’s no bandwidth or thermal penalty for dual Gen 4 NVMe drives in this model.
Charger & Power Compatibility
The Nitro 16 AN16 uses a barrel connector charger rated for 230W. This is a high-power design necessary to support sustained gaming with an RTX 4060/4070 and AMD Ryzen 7/9 processor on a larger 16-inch platform under continuous load.
Compatible charger specifications:
- Output: 19.5V DC, 11.8A (230W)
- Connector: 5.5mm outer, 2.5mm inner diameter (standard barrel)
- Tip polarity: Positive centre
The 230W charger is essential — do not attempt to use lower-wattage chargers (135W or 180W). They will cause immediate and severe throttling during gaming, and may trigger BIOS warnings or power management faults. Always use the specified 230W charger for this model.
Dock & Hub Compatibility
The Nitro 16 AN16 features USB 3.2 Type-A ports and one USB-C 3.2 port (non-Thunderbolt). For a larger gaming laptop, USB docking is less critical for portability but still useful for desktop setups with external displays and peripherals.
Recommended docks for the Nitro 16 AN16:
- Anker PowerExpand 13-in-1 USB-C Hub — Multi-port USB 3.0, HDMI for external displays
- CalDigit TS3 Plus — Premium docking, Thunderbolt compatibility (via USB-C)
- Lenovo ThinkPad Hybrid Dock — Cross-brand support, robust power delivery

Frequently Asked Questions
Can the Nitro 16 AN16 hold two SSDs?
Yes. The Nitro 16 AN16 has two M.2 2280 PCIe Gen 4 slots, both user-accessible. You can install up to 4TB total storage (two 2TB drives) without any thermal or performance penalty.
What’s the maximum RAM for the Nitro 16 AN16?
32GB total using two 16GB DDR5 5600MHz modules. Both SO-DIMM slots are user-accessible from the bottom panel.
Does upgrading to 32GB RAM significantly improve gaming performance on the Nitro 16 AN16?
For pure gaming at 1440p/165Hz, GPU performance is the limiting factor, not RAM. However, if you stream, record gameplay, or multitask (Discord, Chrome, OBS), 32GB provides substantial benefit. Budget players should start with 16GB and upgrade if needed.
What charger wattage does the Nitro 16 AN16 require?
230W. This high wattage is essential for supporting the RTX 4060/4070 and Ryzen 7/9 under sustained gaming load. Do not use lower-wattage chargers (135W or 180W) — they will cause immediate throttling.
What’s the ideal dual-SSD setup for the Nitro 16 AN16?
Two 1TB drives (2TB total) is practical for gaming: OS + software on one, game library on the other. This eliminates drive contention and keeps game load times fast. Content creators should consider two 2TB drives for 4TB total capacity.
