      Are you using this PSU in a Dell server or are you attempting to use it on another (non-Dell) system? Dell server PSUs use a 3.3VSB rather than the standard 5VSB effectively making them proprietary. If you are using this PSU with a non-Dell (or even a Dell that isn't a server) it isn't producing enough voltage on the standby rail to be able to start on a standard motherboard.

              That I honestly don't know. I'm fairly experienced with PSUs but virtually everything I have worked on was standard ATX or similar(non-standard cases and connectors but similar in basic design to ATX). I'm not all that knowledgeable about proprietary, hot-swap, rack mount PSUs like the one you have. I also haven't been able to find much on it from web searches (apart from specs and standard stuff, no in-depth technical information) Hopefully there is someone else on here will have more knowledge/experience in this area.

                  Not sure how much help this will be, but that P/S was made by Delta Products (Newton Power). The nearest Delta division to the UAE is Delta Products India. Maybe you could get some information (or a referral to some one who could help) from their tech support.

                      Troubleshooting of redundant F750E-S0 Dell PowerEdge Server
                      by omega
                      Hello all,
                      as a beginner electronics hobbyist, after a few years I would like to place another post on this Forum section, given that I did not succeed in finding any useful advice among the other posts.

                      Over the last years, I have been using a PowerEdge Dell Server with two redundant PSUs, namely the 750W F750E-S0 ones (aka 06W2PW). Unfortunately, last summer one of them failed (perhaps owing to an overheating), and the server had for working to take into account the other one only. Of course I opened and tried to troubleshoot the failed PSU, but each cap I tested seemed to...

                      Dell E6400 PT434 type Battery Charging Stuck at 1%. Battery Pinouts?
                      by Bowline
                      My question pertains to understanding the control circuity inside a Dell PT434 type battery used in Dell E6400, E6410 and other Dell notebooks?

                      Does anyone have a circuit diagram for the inside of a Dell PT434 battery and/or a description of how the control lines work to control this battery?

                      My reason for asking is I have a battery which I cannot get to charge beyond 1% in a Dell E6410 or E6400.
                      The LED bar graph charge indicator on the battery shows one LED lighted when the info button is pressed.
                      I have tried multiple different Dell power adapters. My Dell...

                      Dell Pro 13 Plus PB13250 Bios Unlock
                      by Akhlz001
                      Hi,

                      Could someone help trying to unlock this BIOS, seems that Dell have changed the layout of new Dell Pro 8FC8 bioses from checking HXD - 4000 bits do not need changing, only 2000. However after FF the section starting from '01000' upto 2000 bits and then soldering the chip back it seems that the microchip on the motherboard is recovering the bios back to original settings after first boot. Has anyone found a way to crack this extra layer of security Dell have implemented? Seems both HP and Dell have upped bios security to match Lenovo by implementing extra measures on a separate...

                      by master3112
                      I would like to share my experience about charging issues with Dell power supplies with the tech community. I am working on a Dell Inspiron 5590, Mainboard 18778-1 with charging problems. The device can be switched on and works so far, only the message appears at startup:

                      Alert! The AC power adapter wattage and Type cannot be determined. The battery may not change. The System will adjust the performace to match the power available.

                      The power supply unit is not recognized in the Bios and the charging process is set to "idle". I use original Dell battery, type...
