I once had 14 or so scsi disks, CD, cd burner, floppy, full height tape in a big box which once had a minicomputer in it but into which I bodged an AMD chipped mobo of some description. All working off one psu. All worked OK, mid to late 90s/early 2000s, anyway that stonking big box retired about the time my daughter was toddling when larger capacity ide disks became cost effective to give disk space. I just soldered on the looms hacked off from a couple of defunct psu's to make a total rats nest of molex connectors and ran two wires outside of the box to the external units to save them having to use their power supplies too, so everything turned on and off from a single switch on a timeclock. As I said, all worked, nothing got hot, stable as all heck for 5 or 6 years over a progressive series of second hand motherboards, with steadily increasing scsi disk sizes as second hand drives got bigger and cheaper. As someone in China once put it, rules are for the obedience of fools and the guidance of the wise... Was a good quality PSU though! Still in use on my file server, though now in a mini tower case with a PII chip and a raided 250gb sata pair on a pci card adaptor. Once that old AT board expires I think it will finally end its days, and it must have been purchased ca 1988 for use on a 386/16 SX system bodged into an IBM XT box. Wonderful what one can do with an angle grinder, eh?
