Dell CSY-240W 240W Power Adapter
This Dell CSY-240W adapter delivers 240W at 19.5V and 12.3A through a 5.0mm x 7.4mm round tip. It accepts 100-240V AC input at 50-60Hz and includes a 3-prong outlet plug. The unit is compatible with Alienware M17 R1 through R5, M17X, M18X, Area-51m, G5, G7 and Precision M6400 through M6800 models.
Who this suits and who it does not
Buyers needing a direct replacement for a 240W Dell Alienware or Precision charger with the 5.0mm x 7.4mm connector will find this unit matches the original voltage and wattage. It also covers 180W, 150W, 130W and 90W requirements at the same 19.5V output. Users whose laptops require a USB-C power delivery port or a different barrel size cannot use this adapter.
Deciding specification: 5.0mm x 7.4mm round tip
The connector dimensions of 5.0mm by 7.4mm are the single detail that determines fit. If the laptop's DC jack matches this round tip, the adapter supplies the correct 19.5V at up to 12.3A. If the jack differs in diameter or pin layout, the adapter will not connect regardless of wattage or voltage compatibility.
