TDK lambda DC-DC converter I6A4W010A033V-001-R

Hello! Optiplex looks like Dell product line - which exactly model? Is this PSU being replaced an external or internal one? I think that it could have some PSU identification circuit (similar to those used in laptops, where laptop detects if original PSU is connected and can - for example -  refuse to charge a battery when not)

Thanks for the reply. 

We are trying to replace the AC to DC adapter provided with the Optiplex3050 as we have only 24V DC source. I guess the sense wire does the PSU identification. Earlier we are able power it with the help of two buck converters LM2596 connected in parallel to power the CPU as each buck converter is capable of 3A. In search of reliable voltage converter we came across this module and want to try it out.

somebody suggests that there are cables from standard ATX to Optiplex connector, but probably with some identification chip included... so maybe this TDK module and a cable with ID chip would be sufficient?

here are some pinouts - it seems that special chip is not needed, but standby 5V possibly will: www.dell.com/.../647f8f68f4ccf8a8de077d92 (verification against original power supply output would be advised - some posts suggest 12V standby or no standby at all for 6-pin connector)

and it seems that Optiplex 3050 needs 12V not 20V so it may be damaged already if it was connected to 20V PSU 

My bad the model is Optiplex 3050 micro. It is given with the 19.5V and 3.34A AC-DC adapter. We are not directly dealing with the power supply going to the motherboard. After these experiments its working as fine with its own adpater and the buck coverter setup I mentinoed earlier. 

So, Please provide the more information or guidelines to make use of the TDK-Lambda converter. That would be really helpful. 

if this is a notebook-style adapter, then Dell is using some sort of signaling on third contact, which - if damaged - is causing "PSU not identified" errors, causing notebooks to run in power-saving mode (and not charging the battery for example).

Here is some information - https://superuser.com/questions/1324643/how-to-bypass-dell-charger-detection#1757185 

Maybe ID chip could be substituted/retrieved from Dell PSU and connected to the third contact of the connector?

JWx Me think you let the Magic Smoke out of the Chips!!!
