Then you've not come across the ones in TK50Z desktop cases (and a few other things). They don't like operating without a minimum load, without which various parts sacrifice themselves to protect the fuse. I once had to sort through a pallet load of them for repair. The bonus was I got to keep three, which now house an assortment of RX50s and small hard drives.
