Dell 240W AC Adapter Solutions — Replacement Chargers for Precision, Alienware & G-Series
The Precision workstation or Alienware has stopped charging and a standard 65W power supply won't be sufficient. The Dell 240W AC adapter provides 19.5 volts at 12.3 amperes — this is the exact amount of wall power that these machines require when in use. We carry the genuine Dell part numbers, matching them by label, and include a one-year warranty.

What Is a Dell 240W AC Adapter — and Which Laptops Actually Need One?
This is the point: a 240-watt charger is not just a larger version of a 65-watt travel charger. It belongs to a different category of power supplies.
19.5V × 12.3A = 240W
A Dell 240W AC adapter takes wall AC and converts it to 19.5V DC capable of delivering up to 12.3 amps. That's what mobile workstations need. A Precision 7000 series with a discrete workstation GPU or an Alienware gaming machine at full boost will draw significantly more than a standard brick can supply. If you undersupply them the laptop will throttle, stop charging under load or just shut down.
The 19.5V 12.3A rating is printed on the label of every genuine Dell 240W brick.
Precision, Alienware, and loaded G-series
The AC adapter with a power rating of 240W is the one that is supplied with Precision 7000-series mobile workstations and with Alienware gaming laptops that are fitted with high-power GPUs. Laptops from the XPS, Inspiron and Latitude lines have a power requirement ranging from 65W to 130W and therefore do not need this adapter—inserting it will not cause them to charge any faster since the laptops only draw the amount of power that they require.
Check the wattage on your original adapter label before ordering anything.
Genuine part numbers, large barrel tip
The precise Dell part numbers — LA240PM160 (PA-9E) and LA240PM190 (0D0X04) — are given so that you will be using a factory-made part and not a general "240W compatible" brick. Chargers with high wattage have a large 7.4 mm barrel tip, and a tip that doesn't match is the usual reason why "my new charger does not fit."
A 240W brick is a genuine replacement only when your original label says 240W.
Dell 240W Charger Models — Both Stocked Part Numbers
There are two genuine Dell part numbers, each of them linked to its corresponding machine, and each button leads to the actual product page.

Dell 240W AC Adapter Comparison — Both Models Side by Side
Part numbers, output and machine mapping straight from each product page. Prices are live as of October 10, 2026.
| Adapter Model | Part Number | Output | Wattage | Compatible Dell | Price |
|---|---|---|---|---|---|
| LA240PM160 | PA-9E | 19.5V · 12.3A | 240W | Alienware & Precision series | $69.99 |
| LA240PM190 | 0D0X04 | 19.5V class | 240W | Alienware gaming laptops | $119.99 |
⚠️ 240W is the deciding number: if your old label says 130W or 180W, a 240W brick is not the correct replacement for that machine. Read the label first.
Which Dell Machines Use the 240W AC Adapter
One card per family. So what does that mean for you? If your machine is not in the first three cards, it almost certainly does not need 240W.
01 / Precision 7000
Mobile workstations
Precision 7000-series machines with workstation GPUs ship with 180W–240W bricks. The LA240PM160 (PA-9E, 19.5V 12.3A) is the 240W match — confirm your label reads 240W.
Buy the Precision 240W Charger →02 / Alienware m & x
Gaming flagships
Alienware gaming laptops use 240W–330W adapters depending on GPU. Both stocked Dell 240W models cover the 240W configurations — match the part number on your brick.
Buy the Alienware 240W Charger →03 / Dell G-series
G5 · G7 · G15 loaded configs
Higher-end G-series configs with big GPUs ship with 180W–240W. If your label says 240W, the LA240PM160 fits the bill.
Check the 240W Charger →04 / XPS
Not a 240W machine
XPS 13/15/17 run 65W–130W, mostly over USB-C. A Dell 240W AC adapter does not fit and is not needed — match the wattage on your own adapter instead.

65W–90W class
Inspiron and Latitude charge from 65W–90W bricks with the small barrel tip. Do not order a 240W adapter for these — verify your label and match the lower wattage.

30-second check
The label on your old brick answers everything: voltage (19.5V), current (12.3A on 240W models), wattage, and the part number (LA240PM160 / PA-9E / LA240PM190 / 0D0X04). Match all four.

Dell 240W Adapter Quality — Genuine Part Numbers, Matched Output
Two things make a 240W replacement safe: the right part number, and the right voltage.
Genuine Part Numbers
LA240PM160 (PA-9E) and LA240PM190 (0D0X04) — the exact Dell part numbers, not generic clones.
19.5V Matched
Output voltage matches the Dell standard — the one spec that must never differ.
Large Barrel Tip
High-wattage Dell bricks use the 7.4 mm barrel — verify the tip on your old charger.
Spec-Listed
Every listing states output, wattage and compatible machines — no "fits most" claims.
Why 19.5V is the number that must match
Voltage is the one spec where deviation damages hardware. Dell's high-wattage platform runs 19.5V; the 240W bricks deliver that at 12.3A. Wattage can be equal or higher for the same voltage platform, but voltage must match exactly — which is why we list the output on every Dell 240W AC adapter we sell.
How a 240W brick behaves when it fails
The warning signs are consistent: the laptop stops charging under gaming or rendering load, the brick runs hot, the plug gets loose, or Dell's BIOS reports "AC adapter not recognized — wattage unknown." If your brick shows any of these, stop using it and match a replacement by part number.
