Reviews for the Acer Predator Helios 18 AI PH18-I71
Acer Predator Helios 18 AI (PH18-I71) review – Stunning Mini LED, Brutal RTX 5090 Performance, Hot CPU
Source: Laptop Media
EN→zh-CN
The Acer Predator Helios 18 AI (PH18-I71) is a colossal desktop replacement built for users who want extreme mobile performance without pretending that this is a thin-and-light machine. It is huge, aggressive, heavy, and unapologetically gaming-focused — exactly what you would expect from an 18-inch Predator with a Core Ultra 9 290HX Plus, RTX 5090 Laptop GPU, and a Mini LED display. The CPU runs extremely hot under heavy sustained load, the fans can be clearly audible even when the system is not doing much, and the otherwise excellent Mini LED panel has aggressive PWM behavior that sensitive users should take seriously. This is a laptop with enormous strengths, but also with compromises that are impossible to ignore.
