The Acer Nitro 5 and Lenovo Legion 5 compete directly in the budget gaming laptop market, and both offer genuine upgrade potential. Neither laptop solders all components, meaning you can expand RAM and add secondary SSDs as your gaming library and workload grow.
This guide compares RAM upgrade ceilings, SSD flexibility, charger specifications, and cooling design to help you choose the better long-term investment for budget gaming.
Quick Verdict Table

| Ports | USB-C, USB-A, HDMI 2.1 | USB-C, USB-A, HDMI 2.1, RJ45 Ethernet |
| Thermal Design | Dual-fan cooling | Dual-fan with Legion CoolBoost |
| Best For | Budget gamers, simple upgrades | Esports gamers, better thermals |
RAM Upgrade Capacity
Both laptops support identical RAM specifications, making this category a tie.
Acer Nitro 5 includes 2x DDR5 SO-DIMM slots, supporting up to 64GB total (2x 32GB modules). Stock configurations typically ship with 16GB or 32GB.
Lenovo Legion 5 similarly includes 2x DDR5 SO-DIMM slots with a 64GB maximum. Same stock configurations: 16GB or 32GB.
For gaming at 1440p/1080p, 16GB is adequate. For streaming, content creation, or heavy multitasking, upgrading to 32GB or 64GB is worthwhile. DDR5 SO-DIMM modules cost £60–£150 each, so a 16GB → 64GB upgrade costs approximately £300–£500. Both allow user upgrades without warranty impact.
SSD & Storage Options
Both gaming laptops include dual M.2 2280 NVMe slots — excellent for gamers with large libraries.
Acer Nitro 5 typically ships with one primary drive (512GB or 1TB) and leaves the second M.2 slot empty or with optional secondary storage. Adding a second NVMe drive is straightforward, requiring no tools or screwdrivers.
Lenovo Legion 5 similarly includes two M.2 slots with identical flexibility. Stock configurations are comparable to Nitro 5.
Having dual drives is huge for gaming — store your OS on a fast 1TB NVMe and your game library on a secondary 2TB drive. This costs approximately £100–£250 for a 2TB secondary SSD. Both accept any standard NVMe drive (Samsung 990 Pro, WD Black SN850X, etc.).
Charger & Power Delivery
Both gaming laptops require substantial power, and charger wattage is critical for sustained gaming performance.
Acer Nitro 5 ships with 140W–180W proprietary DC barrel chargers depending on GPU configuration. Replacement chargers are specific to Acer models — you cannot swap them with Lenovo or other brands. Replacements cost £50–£100.
Lenovo Legion 5 includes 140W–170W proprietary DC chargers, also brand-specific. Lenovo chargers are not interchangeable with Acer or other manufacturers.
Higher wattage (180W vs 140W) provides slightly better sustained GPU/CPU performance during heavy gaming sessions. Difference is minimal for most games — a £30 wattage difference won’t dramatically change frame rates, but it does help with consistent performance under sustained load.
Ports & Connectivity
Acer Nitro 5 includes 1–2x USB-C, multiple USB-A ports (3–4), and HDMI 2.1. No built-in Ethernet (RJ45), so online gaming relies on Wi-Fi or USB Ethernet adapters.
Lenovo Legion 5 includes 1–2x USB-C, multiple USB-A, HDMI 2.1, and crucially — a built-in RJ45 Ethernet jack. For esports gamers who need wired network for competitive play, this is valuable. Wired Ethernet eliminates Wi-Fi latency, which matters for Valorant, CS:GO, or Apex Legends tournaments.
Legion’s Ethernet is a meaningful advantage for competitive gamers. For casual players, Wi-Fi is fine, making this minor difference.
Thermal Design & Cooling
Acer Nitro 5 features dual-fan cooling with standard thermal paths. Thermals are adequate for gaming at stock settings but can reach 85–90°C under sustained load.
Lenovo Legion 5 includes dual-fan cooling PLUS Legion CoolBoost technology, which aggressively ramps fans and adjusts power delivery to optimise thermals. Legion typically runs 5–10°C cooler than Nitro 5 under identical load, translating to better sustained GPU/CPU boost clocks.
Better cooling = longer lifespan of components and better performance consistency during long gaming sessions. If you play for 8+ hours daily or plan to keep the laptop 5+ years, Legion’s thermal advantage is worth considering.
Which Should You Choose?
Choose Acer Nitro 5 if: You want a straightforward gaming laptop with standard upgrades (RAM, SSD) at a lower price point. Thermal performance is adequate for casual gaming.
Choose Lenovo Legion 5 if: You’re an esports or competitive gamer (need Ethernet), you plan long gaming sessions and want better cooling, or you value Legion’s ecosystem support and warranty. Better thermals = longer laptop lifespan.

Frequently Asked Questions
Can I upgrade RAM to 64GB on both laptops?
Yes. Both Acer Nitro 5 and Lenovo Legion 5 have 2x DDR5 SO-DIMM slots supporting up to 64GB maximum. Both are user-upgradeable without warranty impact. Stock upgrades to 64GB cost £300–£500.
Do both have dual M.2 SSD slots?
Yes, both include 2x M.2 2280 NVMe slots. Most stock configurations ship with one drive and leave the second slot empty or optional. Adding a second 2TB drive costs £100–£200.
Which charger is more powerful?
Acer Nitro 5 chargers range 140W–180W, while Lenovo Legion 5 offers 140W–170W. Slightly higher wattage on Nitro 5 doesn’t meaningfully impact gaming performance — both are adequate for sustained gaming.
Are the chargers interchangeable?
No. Both use proprietary DC barrel connectors. Acer chargers cannot charge Lenovo laptops, and vice versa. Replacements are brand-specific and cost £50–£100.
Why does Lenovo Legion 5 have an Ethernet port?
Built-in RJ45 Ethernet is valuable for esports/competitive gamers who need wired network for tournaments. Wired eliminates Wi-Fi latency (critical for Valorant, CS:GO). Casual gamers won’t notice a difference.
Which runs cooler during gaming?
Lenovo Legion 5 typically runs 5–10°C cooler thanks to Legion CoolBoost technology. Better cooling = longer component lifespan and better sustained performance on long gaming sessions. Acer’s cooling is adequate but less sophisticated.
