I run my AT (10Mhz with 640K onboard and 2Mbyte on an ext-card, 2 HD's (Nec 
5126), 2 1.2M floppies, modemcard, Paradise EGA-card, 2 serial cards, 1 
printer card and a DTC HD-controller ) with an old 100W PC-power supply...
 
And i have an another machine without case but with a 50W power supply..
(It's a 8Mhz AT-mothercard with 640k memory, 2HD's (CMI 6640 and BASF 6188)
, 1 360K floppy, IBM 64K EGA-card, multifunction-card and Adeptec 2010-
controller). I'ld swap a fuse to get the power supply to work... :-)
