I needed a 180W 19.5VDC Dell AC adapter for a Dell OptiPlex micro-tower and got a 240W adapter 'just in case'. What a difference. Not only did the 'underpowered AC Adapter' warning disappear and the performance improve but the fan began running less and the core temperatures dropped about 20'C; I assume that the lowered performance taxed the CPUs more and caused them to run more. Now, I mostly set it and forget that it is there (that is a compliment). It retains the blue-ring power-on indicator on the 7.5mm plug, like the Dell OEM adapters, so you can see the power supply status, at a glance. It is fairly large and heavy, though: about 8"x4"x1" and 625g/1.5 lbs, without cords, which is no issue in a stationary use, like mine, but you might want to consider the size and weight if you are lugging your laptop around a lot. All in all, a fine item. Recommended.
