ASRock P4i65GV with fake Chemicon KZE ?

[Brian C]

Below are KZE capacitors used in ASRock P4i65GV and ASUS P4SD-LA skt478 mobo. Same voltage and capacitance but different in height... could it be fake ? I think the darker brown and taller KZE is the genuine part.

frankly speaking .. I had no clue which is real or fake or both real or both fake

From KZE datasheet the standard dimension is 10mm Dia. and 25mm Height.

Maybe the different type are "custom size" .

most likely custom size.
or the manufacturing process improved with time to alow same specs in a shorter can.

Capacitor Parameters for both KZE
---------------------------------
ASRock KZE: at 1kHz: 1207.5uF, esr 18mOhm
at 10kHz: 1370.2uF, esr 15.3mOhm
ASUS KZE: at 1kHz: 1154.7uF, esr 15.9mOhm
at 10kHz: 1360.2uF, esr 13.6mOhm

Almost same ... perhaps it is custom made KZE.
