We must be looking at different PSUs, then - all 4 of the PSUs I've bought between 2006 and 2012 have had on-off rocker switches. Maybe you just don't go for the top quality brands?
Well, in the last 10 years, I've seen power switches only once.... on the back of a Sun Microsystems workstation.
I've not seen them on Apple, HP, Lenovo,Supermicro or FujitsuSiemens kit amongst others (either desktops or servers).
So there, looks like you're the one with the cheap crud....
