RE: Zerozone 100VA PSU Fuse Issue

If as you state your load is 3A max @12V that's 36W. Not counting losses that would be 0.6A @120V. A 1.6A slow blow would seem to be adequate. Could be that there is a current surge at turn on. Those caps look big.. Have you got a schematic? Is there a small value resistor between the bridge and the first cap? Then again you could do as suggested and try a larger fuse to try to lessen the number of nuisance blows.
