Re: dell psu



I made my 16 pin extension out of a 24. Since the 24 is point to point more wires than I need but the needed wires are also there. Last extension at hand. Hopefully I willnot need to do this again. I have more 16 pin PSUs that are dead. Make good hosts for connectors....

Re: dell psu



I cut and spliced the 9 wires in the 16 pin so it would reach. I have no idea of which wires are used. So I kept it the same. I also used a 24 pin extension. Nest time I will try to make a 16 pin out of the 24 pin and see if it fits Each opening alternates between a round and "D" shape. It may not be possible....

Re: dell psu



I have come to the conclusion the mobo is the culprit. 3 new psus do not change the orange led. all 3 use pin 13 for power on, 24 plus 16 pin connectors. is there such a thing as a 16 pin point to point ats connector extention? I can find a 24 but the 16 seems not to exist. to finish my last project I needed to cut and splice the 16 pin to make it longer by 8 inches or so. I needed to move the psu to an unusual location since I was using a large DELL mobo and the HP case was not tall enough. Any sources for the extention welcome....

Re: dell psu



My issue is the exact opposite. The PSU WILL turn on when shorted ps-on to ground. But the mobo will not turn on when connected. More PSUs coming to vrtify that the 25REH mobo is indeed no good. More 4H665 mobos coming to match the PSUs. As long as the mobos power up I will be happy....

Re: dell psu



the PSUs at hand are non standard atx 24 pin. #13 is power on with 3 black gronds adjacent. the wire is gray. the model #s vary but so far the wiring is thae same. I have a 25REH mobo I am pretty sure is no good as three PSUs fail to power it up. steady orange led on the power board. new 4H665 mobo coming pulled from a working system....

The psu #5251D and the #NPS250 and the #24RGY are all similar. I have been told that the POWER ON wire for the 5251 is GRAY position #16 in the 24 pin molex. For the NPS it is GREEN position # 13 or # 16. For the 24 it is also GREEN in position # 16. Is all this correct? Is power on accomplished by shorting this single wire plus ground? A wire diagram or simple chart for these 3 PSUs would be welcome. Also what is the 3 main rail voltages? For the 5251 it is supposed to be 12 but it reads 11.75. the other two are also under. Is this the cause of a SOLID ORANGE led on the power board? I have been...
