A friend handed me 4 Dell GX280 all with bloated Rubycon caps near the CPU. I haven't opened up the power supplies, but they are 5161-7DS (20 pin).
According to diagram DC Power Connector P1 (about halfway down the page)
http://support.dell.com/support/edoc...g/pwrsply0.htm
pin 14 is PS_ON and pin 9 is 5V FP.
Normally, for an ATX power supply, I use a paper clip and short PS_ON to GND and the power supply turns on. From the diagram, this looks like an ATX power supply and all the pins correspond to an ATX power supply.
I can't do this for the 5161-7DS for some reason. I took a working 5161-7DS and tried shorting PS_ON to GND and got nothing. I tried adding a load (SATA hard drive) and still nothing.
Q1) What am I missing?
Q2) What does "FP" stand for in the 5V FP documentation?
