Most AC adapters we've seen typically stay under 50 C when stressed and rarely do they ever go beyond 60 C. If you own the small 90 W AC adapter that ships with the latest XPS 15 series, however, then you might want to be extra careful about where you position it.

We're currently in the midst of reviewing the XPS 15 9500 with our full review coming soon. In the meantime, however, we want to bring attention to its compact 90 W AC adapter that ships with the base configuration. When the system is under high loads for long periods, the adapter can reach uncomfortably high surface temperatures of 60 C as shown by our temperature map above.

Of course, warm AC adapters are not uncommon, but 60 C is warmer than almost every AC adapter we've seen thus far (the Razer Blade 15 AC adapter is the notable exception at 65+ C). Even the 130 W AC adapter that ships with the XPS 15 7590 Core i9 approaches "just" 50 C when under similar load conditions.

We suspect that the high temperature can be partly attributed to the small size of the AC adapter. At just ~13 x 6.5 x 2.3 cm, the Dell adapter is smaller than most others including last year's 130 W version that shipped with the XPS 15 7590 Core i9. It's a compromise that users will have to make at the moment if they want more portable AC adapters for their Core H-powered laptops.

If you own or are planning to own an XPS 15 9500, then we definitely recommend keeping the AC adapter away from cables and other sensitive items just to be on the safe side.

The 90 W XPS 15 AC adapter is more compact than most, but it can grow warmer as well when under load

After graduating with a B.S. in environmental hydrodynamics from the University of California, I studied reactor physics to become licensed by the U.S. NRC to operate nuclear reactors. There's a striking level of appreciation you gain for everyday consumer electronics after working with modern nuclear reactivity systems astonishingly powered by computers from the 80s. When I'm not managing day-to-day activities and US review articles on Notebookcheck, you can catch me following the eSports scene and the latest gaming news.
