Acer Helios 18 (2025)

Configs to buy / avoid: The RTX 5080 configuration is the better buy, as the RTX 5090 in our testing reached throttling limits, despite the larger chassis design and plenty of room for cooling - very unusual for an 18". Avoid the 192GB RAM config unless you genuinely need that capacity, because the slower DDR5-4000 speed hurts performance. Testing notes: Our tested Helios 18 delivered a full-powered RTX 5090, four RAM slots, three M.2 slots, a 4K Mini-LED screen around 700 nits SDR and close to 1000 nits HDR, 4K 120Hz and 1200p 240Hz display modes, good keyboard surface temps, solid Linux support, and unique snap-on mechanical keys. Trade-offs: The main compromises were thermal throttling under heavy load, the loudest fans tested all year, lower gaming and CPU performance than similarly specced rivals, poor battery life, slower memory at high capacities, limited BIOS tuning, and Type-C charging not working in our tests. Alternatives: If upgradeability is your main reason for considering the Helios 18, consider the Lenovo Legion 9i because it offers even more expansion and better overall performance, though it is more expensive. ASUS's Scar 18, Razer's Blade 18 or Alienware's 18 Area-51 are all objectively better than the Helios 18 based on our testing.
