Fujitsu FMV-AC323B AC Adapter for Fujitsu FMV LIFEBOOK AH Review
Fujitsu FMV-AC323B AC adapter for the FMV LIFEBOOK AH-X/D3 (FMVAXD3B).
FMV-AC323B is the genuine Fujitsu adapter for the LIFEBOOK AH-X/D3 (FMVAXD3B), the OLED, Core i7-9750H class model in the 2020 AH range. Fujitsu's option page lists it for the AH-X/D3 and the FH90/E2. It is a higher wattage unit than the 90W FMV-AC343A the other AH models use, and we would not swap it for that one. A seller listing shows 19V 5.27A, about 100W, but Fujitsu's pages do not confirm the output, so match the label on your old adapter.
Fitment answer
OEM confirmed for the LIFEBOOK AH-X/D3 (FMVAXD3B). Fujitsu's 2020 option page lists FMV-AC323B for the AH-X/D3.
Output is not confirmed by Fujitsu. A seller listing shows 19V 5.27A, about 100W. Check the label on your current adapter before buying.
Which laptops this fits
LIFEBOOK AH-X/D3 (FMVAXD3B) only, within the AH line of this generation. Fujitsu's option page also lists it for the FH90/E2.
The other 2020 AH models (AH77/E3, AH53/E3, AH50/E3, AH43/E3) are listed for the 90W FMV-AC343A instead.
Connector and wattage checks
Wattage: the AH-X/D3 carries a Core i7-9750H class CPU and Fujitsu pairs it with a higher wattage adapter than the rest of the AH range. Do not run it on the 90W FMV-AC343A or the 65W FMV-AC332A.
Connector: we have not confirmed the plug size from Fujitsu. Compare the plug on your existing adapter.
Voltage must match exactly. Wattage can be equal or higher, never lower.
Genuine vs third party
Fujitsu sells FMV-AC323B as a genuine option. Fujitsu does not publish whether its barrel adapters carry an ID signal, so how a third party adapter behaves on the AH-X/D3 is unknown.
We would buy the genuine unit for this model. It is the highest power machine in the range and the one most likely to throttle on an underpowered adapter.
If this is not yours
Read the part number printed on the adapter you are replacing and the model code on your laptop's label. If neither appears on this page, this is not your part.

FAQs
Can I use a higher wattage adapter on my AH-X/D3?
Only if the voltage and plug match exactly. Voltage is fixed, wattage is a floor. We have not confirmed FMV-AC323B's output from Fujitsu, so read the label on your current adapter first.
Can I use the FMV-AC343A instead?
We would not. Fujitsu lists FMV-AC343A for the lower power AH models and FMV-AC323B for the AH-X/D3. A lower wattage adapter can leave a high power laptop slow to charge or unable to charge under load.
Why does my laptop say plugged in, not charging?
On a third party adapter, suspect wattage or plug fit first. On a genuine FMV-AC323B, check the plug is fully seated and the AC cord is undamaged before blaming the battery.
