Primergy (760) power connector & 5.25" drive plate

Postby vandermeerschw » Sun Oct 27, 2002 16:47

I have an old primergy 760, but the motherboard is damaged, and I'm trying to modify the enclosure into an ATX compatible one so I can put in a different board. But the power connector looks like ATX but isn't (22 pins instead of 20 and non-coloured wires so I have no idea what to connect to what). Can anybody supply me with the pinout of the connector? Does it even deliver the required voltages for ATX systems? Thanks in advance. Also i'm missing the 5.25" & floppy bays cover plate (not the individual covers but the one that covers the screws of all the drives, is this still available for ordering or does anybody have one to spare?

The Promergy 760 has a D887 Maiboard according to <A HREF="http://www.fsc-pc.de/support/softwareassist_e.asp" TARGET=_blank>http://www.fsc-pc.de/support/softwareassist_e.asp</A> <P>Here is the manual: <A HREF="http://www.fsc-pc.de/support/drvupload.asp?DRV=3144&LG=EN&Info=Download" TARGET=_blank>http://www.fsc-pc.de/support/drvupload.asp?DRV=3144&LG=EN&Info=Download</A> <P>The power supply connectors don't look ATX compatible to me either.<P>Generally the Primergy Servers have special Power Supplies. I guess you won't be able to use them with an ATX Mainboard.

I measured the voltages on the connector, and it seems to have all the voltages needed for ATX operation (+3.3 +5 +12 -5 -12), so I think this is possible, but an exact pinout of the pins on the big power connector and the two small ones would really come in handy

I'd say forget about it anyway. You will not only need the right voltages, but also enough current. If you would use a new ATX Mainboard it would most probably need too much power for the ancient power supply. Also in those times 5V was used for supplying the CPU voltage regulators, while today with P4 it's 12V. So the power distribution is different.<P>What do you really want? Keep the case?<P>Why not try to modify the case to accomodate an standard ATX power supply then?

i figured the triple power supply should do it. Since it has to power 4 Ppro's and 6 scsi hd's, It will most probably be sufficient to power a dual P3 or something. Anyway I am going to try it, with or without pinout.<BR>

Good Luck.<P>But be aware that you are about to kill a dual PIII Mainboard...
