I have here a Farnell N110P411 open-chassis SMPSU. On a relay on one
end of the board there is a white sticker with the text "TORCH
COMPUTERS LTD (C) 1983" and a QC stamp.
If anyone would like this (free, you pay shipping) as a spare part or
for a repair/restoration, please speak up by private email. I'm
clearing out some old stuff and I won't be able to keep this for too
much longer before it gets recycled.

I expect that's the one used in the Torch Triple-X - it's about 125W I
think...

I am pretty sure the Quad-X used the same PSU, but I am not pulling the
not-quite-complte one out from under my bed to check.
If it is this supply, it's a fairly standard SMPSU giving the normal
outputs, with a soft power switch. THere are 2 contacts at the front of
the PSU chassis (connected to a 0.1" 'Minicon' on the PCB) that go to the
touch switch contacts themselves. TOuching those turns on the relay
(powered by the NiCd on the board), it's held on by a signal from the
mainboard, which can then also turn the supply (and thus the machine) off.
I have a hand-drawn schematic of the XXX supply (and the rest of the
machine for that matter).

Yep, that's my recollection too. Same deal as you though, the Triple-X
and Quad-X machines are in the loft and I wasn't motivated enough to go
dig them out! :-)
Having said that, I think the Torch 725 has a Farnell PSU in it (just
not with the soft-start of the T-X or Q-X). Hence it might be a supply
for one of those (lack of the NiCd would be a clue there)
I have a feeling the Triple-X VME expansion slice used its own Farnell
PSU too.

And you were kind enough to furnish me with a copy of that :-) I think
it was the only Torch schematic that I didn't have...

The presense of the relay suggests some kind of remote power switching.

You mean the quinring? (the slimring, one slot VME slice, took its power
from the main PSU). There should be a schematics for
the PSU in my
quinring i nthe pile of schematics I gave you, I can't remember
if it's a
Farnell unit or not.
