Using a higher-wattage charger with the MSI Prestige 16 AI+ can raise power consumption, but it won’t suddenly turn the laptop into a noticeably faster performer. In benchmark testing, the performance gains from stepping up to a 140 W AC adapter were small, landing in the low single digits compared to the included 65 W adapter. Multi-thread results showed only modest improvements: CineBench R15 Multi-Thread increased from 2937 to 3033 (about 3%), while CineBench 2024 Multi-Thread moved from 980 to 1030 (about 5%). In everyday terms, that’s a difference most users won’t feel outside of side-by-side measurements.
Where the higher-capacity adapter really matters is charging behavior under heavy load. If you’re pushing the Prestige 16 AI+ with demanding games or intensive software, a lower-watt charger can struggle to provide enough power for both the system and the battery at the same time. One clear example comes from charging at 56% while running Cyberpunk 2077: with the 65 W adapter, the battery percentage stayed stuck at 56% rather than climbing. Swapping to a 140 W adapter allowed the laptop to begin charging at a normal, dependable rate.
The reason is simple: demanding workloads can consume most of what a smaller charger can deliver. Cyberpunk 2077 on its own can draw over 60 W, leaving almost no extra headroom for charging when you’re using a 65 W power adapter. In that scenario, the laptop may run fine on wall power, but the battery may charge extremely slowly or not at all.
For MSI Prestige 16 AI+ owners, the practical takeaway is straightforward. If you frequently game, render, compile, or run other power-hungry applications, using a higher-watt USB-C power adapter—around 100 W or more—can make charging far more reliable during heavy use. If your workload is lighter or you prioritize portability, the included 65 W adapter remains sufficient and is easier to travel with.
This makes the upgrade decision less about chasing speed and more about improving charging performance under stress—especially for users who want their Prestige 16 AI+ to gain battery percentage even while running demanding tasks.
