I need help with my Dell OptiPlex 960 SFF PSU Pinout, I need the correct PIN out wires colour the service manual shows the 24 PIN out wires location and colour but this does not look the same in my P1 connector to the Motherboard, how can I find the correct PIN out colours? any help is very much appreciated, thank you
Solved! Go to Solution.
Hi @draly ,
Page #127 on the service manual shows the 24-pin combination like this:
|Pin Number||Signal Name||18-AWG Wire|
|4||VCC (+5 V)||Red|
|6||VCC (+5 V)||Red|
|13 (optional)||+3.3 VDC||Orange|
|21||VCC (+5 V)||Red|
|22||VCC (+5 V)||Red|
|23||VCC (+5 V)||Red|
*Use 22-AWG wire instead of 18-AWG wire.
This one from Lelong.my shows like this:
Another one from Amazon shows like this:
Take orange as example, pinned at 1, 2, 12 & 13 which matched with what the service manual described.
Best policy: locate the original part number from label of the old PSU and find exactly the same one for replacement.
You can get a new tower for the cost of windows alone.
The reason to get a tower is so that you can buy a regular power supply when it fails.
Hi, The P1 connector I have has different colour connectors to PINs as if misaligned for example the yellow wires that should connect to PIN 10 and 11 are connected to PIN 7 and 19, this is problem that I cannot use standard PSU to replace the power neither PSU power tester, what shall I do?
Hi the Tower model is bulky also the CPU is not as fast as my SFF PC, I want to check the PSU is fully healthy I tried the PSU power tester in the market but it look they made to test the standard 24PIN connector, then I noted the 24PIN connector I have may not be standard as wire color does not match PINs as if they are misaligned.
Again, locate the original part number from label of the old PSU. It should be a Dell P/N with 5-digit.
Hi, I have located the Dell part but I wish to test the present PSU it look most likely healthy any help in testing the PSU alone?thank you
that is the MT psu in photos, the motherboards and PSU are different for sure the small SFF with a stepped psu.
you are on the wrong page, sorry.
page 133 up is SFF, behind that page is not his PC.
nobody has the PSU pin out on his SFF 960.
google searches give no clues.
