My experience with a H7822 is that when all the diagnostic LEDs stay lit,
DC OK is probably not getting asserted so the power supply might still
not be working 100% correctly. In the H7822, DC OK seems to be the
purple lead and high (something around 4V-5V) means asserted.

the bitsbox one may be a teensy bit to large but
the ebay one should
fit nicely. Neither is too expensive even with postage so I'll buy a
few, given that I do have a fair few PSUs knocking around.
Just a quick follow-up in case it helps someone else down the line. I've
put the system back together and the H7822 PSU seems to work: with the
mainboard connected the green LED lights (and the fans spin). So that's
good.
The mainboard stays in the reset state (all diagnostic LEDs lit) so that
might still be an issue with the PSU DC OK signal or the mainboard
itself. However, at this stage the PSU is behaving as expected.
