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).

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