need help identifying weird power supply

Hi

I inherited an old ICL Teamserver from work. A dual-PII-350 (that's
the Slot 1 chips, not Sockets) with 512mb ram, onboard SCSI, USB, PCI
Mylex RAID DAC960PG etc. Quite a serviceable machine.

However, the power supply makes quite a racket, so having a spare ATX
PSU lying around, I grabbed an AT->ATX converter cable and went to
plug it in. When I found that the AT-style motherboard and PSU were in
fact not standard AT...

Can anyone help ID what the other weird connectors are? I tried
powering up on the ATX-modded system to see if it mattered without
them, and sadly it did.

Went googling before posting, and found this post:
http://www.duxcw.com/yabbse/index.php?board=6;action=display;threadid=5176

As he says, it's a DPS-280BB from delta.

Sadly, no help there (the link to a replacement wasn't yielding
anything useful). And thankfully, the guy also took a picture of his
weird connections, which saves me having to :)

Any thoughts? Is this something like an extended AT PSU or something I
can find and replace quite easily?

Thanks in advance

The fatter ones appear to be PSU to board connectors. The others, I've no
idea, they appear on all the ancient PSUs I have (and I have a box of around
20 in the loft. Why? I've no idea!) and I've never known what they were for!
Kony will, though.

The fatter ones by the coding of the wires (and the features of the
board) I would expect to be extra power supplies to certain rails, ie
extra 5 volt supplies or whatever. Packed with green, or red, or black
wires, which would suggest there's not a hell of a lot of variation in
them, perhaps two different voltage sets...

They aren't the normal ATX-type connectors, notice one of them is
10-pin and the other is 12-pin. Only the 12-pin is used on my board
with the 10-pin hanging loose.

The two leftmost connectors are the normal AT power connectors.

Funny you should mention Elgin - I tend to go there of an occasion.
Not sure about the marble loss however.

I've no experience with ICL Teamservers, suggest taking
voltage readings, or abandoning the system altogether since,
when all is said and done, it's still only a dual 350MHz
box. A 800MHz emachine with a 120GB HDD in it will run
circles around that old thing. Unique power supplies for
servers fetch a pretty penny too, could easily cost $200 or
more to replace it unless OP feels like grafting the old
wiring harness to a different power supply and even then
there's no guarantee there wouldn't be proprietary signals
needing supported by some additional circuitry or mods.

ON the other hand if the only problem is "noise", it's
probably the fan, should just be swapped. Hard to say but
it might just be higher fan RPM due to it not being a "PC",
rather a misson-critical oriented box that focuses on
cooling rather than noise control. In general the Delta
power supplies are pretty good and any non-Delta replacement
might be a downgrade.

If there is some other faulty part in the current PSU, it
still might be easier and/or cheaper to just fix it.
