Checking for dead power supply and replacement

[Licensed to Quill]

I have this Toyo Slot 1 computer which is completely dead. Nothing. Not a
bean no fan, no whirring from drives, no lights, no action nothing.

SEEMS like a dead power supply although if anyone out there thinks it could
be the SY-6BA+ Motherboard, please say so: I have heard that NEWER power
supplies will not
switch on internally unless there is a load from the motherboard and
possibly some drives. So I suppose if there is a problem with the MB it
might not be switching on?

I cant believe that the Toyo is all that new and is probably one of the
first Slot 1 Pentium 2 computers, - running at 450 Mhz? The power supply
is a Toyo FSP235-60GI which only has conectors to the MB and devices
(as opposed to having a power switch connector as well) and I have an old
Dell PS5231-1 power supply which has the same connector block which I could
put in
to check. All the coloured wires on the blocks are different, although the
wires on the Toyo are marked as to voltages (the Dell just gives general
specifications, - they both are either 230 or 235 watts).

Does anyone know if this is advisable or is there a real possiblity that it
might just fry the Toyo MB?

You can ground the green wire (pin 14) on an ATX supply and force it to come
on, although the system will probably still be held reset if it didn't initiate
the power on sequence. You will see the drives and fans spin up.

Hang about a moment, I am arguing that the power supply is dead which is
causing the total non-functionality of my computer? Do you seriously not
think this is the case?

What I was wondering was whether I can just switch it for the Dell power
supply? Or might this fry the motherboard if too much voltage is supplied
through some of those wires?

I guess I am just asking about the transferrability of power supplies
between computers and whether there is any uniformity between those plugs
that go from the power supply into the computer?

The Dell supply is very likely a special one, and it will fry
the mobo if the wire colors aren't the same as the Toyo.
Is the Dell like this?
This is the 20 pin for a Dell.
1 +5 VDC (red) 11 PSON#2 (brown)
2 Common (black) 12 Common (black)
3 +5 VDC (red) 13 Common (black)
4 Common (black) 14 Common (black)
5 PWRGOOD1 (orange) 15 -5 VDC (white)
6 +5 VFP (purple) 16 +5 VDC (red)
7 +12 VDC (yellow) 17 +5 VDC (red)
8 -12 VDC (blue) 18 +5 VDC (red)
9 Common (black) 19 Not connected
10 Common (black) 20+ 5 VDC (red)

I agree with Gfretwell that the supply probably isn't the problem.

This is all a bit of a pity as I only obtained this computer because I
thought the mobo might work in an Aopen in which the mobo has gone south

So anyway if I unplug the power supply and put a voltmeter across that green
wire to the ground (and then check the other values) and it reads, this
means that the power supply is OK? There is no real question of the
motherboard needing to put some load on the power supply to get it to switch
on?

What you really need to do is get your hands on a standard power
supply. I didn't know that Dell power supplies were different, until
I tried a standard one on a Dell PC. Dumb move, but I didn't fry
anything.

Checking your set-out, my Dell is the same except that pin 19 is conected to
a brown wire.

Therefore, don't use it except with a Dell.
