Not true; there were a number of reports of the M3 Real blowing fuses when it was first released, though the problem seems to have mostly been fixed. Other carts have had this issue as well, but I'm singling out the M3 Real because I know you like it.
As for noobs causing the problem themselves, how? The cart only goes in one way, and only a short or an electronic defect could cause a blown fuse.
You are correct about this not being a big problem though. Even the N5 wasn't particularly likely to blow a fuse, just more likely than most other carts.
