Can't plug PS into motherboard ...

I had a Power Supply plugged into the Tyan BX-chip motherboard of this
system for a few years. Then one day I needed the PS for another system. The
Tyan sat around unused for about a year. Now I want to resurrect it. However
neither of 2 different PS's that I try ... will seat all the way on that
part of the socket on the motherboard that is near the "top" of the
motherboard. I have examined the pins with a magnifying glass. It looked
like one of them might not be quite perfectly centred. I straightened that
one with a very small screwdriver. But no change. Something that's hard to
see is keeping the plug from seating evenly.

I have taken it to a shop that I deal with and they are similarly stumped.
They speculate I might have removed the previous PS in a clumsy manner, and
bent some pins ... but it doesn't quite make sense, as they don't look
seriously bent.

Any suggested fixes are appreciated !

Question,

Are Power supplies AT, ATX, or BTX form factor and is the Tyan an AT?

You say BX chipset? sounds AT and your supplies are ATX.

Please show me anywhere that you can find a BX chipset based motherboard
that was AT. If any existed, you'd be hard pressed to find them. BTX
power supplies are not in general circulation at the moment, so I think
you can logically rule that one out. AT power supplies have connectors
radically different to the ATX power supplies, so I would doubt that the
OP would be making that error. In all likelihood, he's having a problem
with an ATX power supply not seating properly on an ATX board. What I
would like to know is:
is the little retainer clip type thing on the ATX motherboard power lead
clipping in place, and does the board fire up at all?
 
It would be best to give the Model number of the Tyan M/B, as I work
as a service eng with more than 200 manuals for Tyan and they are some
15 using the Intel BX chip set.
 
Yes, it is a ATX ... it is a Tyan Tiger something ... a full-size dual
Slot-1 motherboard.

No the plastic hook/retainer in the middle of the power lead from the PS ...
does not clip. That cannot happen unless the plug is pretty well seated.

Yes the motherboard will boot up, so some contact is there ... but it may
not be GOOD contact ;-)

Thanks !
 
As I said to previous poster, it is an Tyan Tiger dual Slot-1 and
deffinitely a stardard ATX. It is *not* some non-standard connector.

AT/ATX are way differetnt to confuse plugging one into the other.
 
Yeahhh don't know why I looked at that BX and put the relationship to
AT I was contemplating a shuttle 233 BX board I had,,,,,but after
sleeping on that,,, was ATX also. So spacing out on that one. Having
a problem with an ATX PSU to An ATX MB is very uncommon...pretty cut
and dry, so I was going on the 'not practical' approach. Although I
did see one that had the MB male still attached to the PSU connector,
Guy ripped the damn thing right off the MB.

If you can't see any problem, do you have another psu you can try and plug
in? If it plugs in ok the fault is with the original psu plug, if it
doesn't fit it must be the socket on the mobo.
I've had a couple that were very tight, but never had one that I couldn't
persuade to go in.
 
Hi, thanks ...
As I said in my original post here "However neither of 2 different PS's that

Any other thoughts? It seems to be a rare problem !

I have checkout all Tyan M/B from S1682D, S1686D, S1692D, S1696DLUA,
S1696DLUASCSI, S1832DL, S1836DLUAN, S1952DLU, S2065DLLAN and
S2165DLSCSILAN and all use a ATX type psu. Try and find the M/B model
number and I will check our database on Monday and let you know what I
find.

Maybe the sockets on the PSU plug are mis-aligned.
 
PSU means Power Supply Unit ? I have tried 2 different ones that work on
other ATX motherboards ... and the shop has tried a 3rd good one. But still
no dice.

Alignment/plugging-in is being done under good light, with head-band
magnifier and/or reading glasses .... with no CPU's plugged in (to obscure
view of motherboard's PS socket .... and still no dice ...

The plug/socket almost go together. It is *not* like they are the wrong part
number !! Wierd, huh ?

To RS. I have tried to send you a some information but your email
address is no good [IE bounce].
 
Just remove the 2 'X's in my email address ...

This is informative and useful ... especially the tip on how to trick an ATX
PS to run the way the old AT PS could be run .. i.e., plug it in !! But
so far nobody seems to have any theories why an ATX female socket won't
accept an ATX male plug ....
