well.. i decided to finish the cabinet without waiting for an answer to my questions (i'm not patient enough) :D now the power supply, the monitor and the marquee bulb are protected by an emi-filter and until 30.000A overvoltage (with a 10A fuse). In case something fails the filter has a 5.000.000$ insurance against malfunction (hey, really.. it's written!). The arcade power supply has an internal fuse for additional protection and the monitor has another fuse. So i think, the three fuses, the EMI filter and the 5.000.000$ insurance should give enough protection. (my girlfriend keeps asking why the most cheap electronic machine at home has such extreme protection) :D Is really necessary to add a fuse to the 5V and 12V lines that goes from the PS to the PCB? Thanks! |

I think you keep missing the point that things can happen in different places on the circuit AND the point that it ISN"T the power supply that the fuses are meant to protect, but it is the expensive PCB and monitor. A failing or failed power supply can crank massive voltage to a PCB and it will do so WITHOUT blowing any of the fuses installed on the AC line. But, I already said that, and then you repeated yourself. So, do what you wanted to do in the first place. You obviously don't think a $200 PCB costs enough to be worth a 5 cent fuse, so by all means leave it off. Also, computers are fused. They have one in the power supply, and are supposed to be used with a surge protector, which is also fused. |

hey, i know.. i dont have problems to add fuses. but i wanted to know "where" and "how"... now i have 3 fuses.. i hadnt seen any tutorial that set ups so many fuses but I still think that the fuses I have right now are just not enough (not placed in the right position) In the tutorials Ive seen (bob roberts.. etc..) there's only a single fuse installed between the mains and the powersupply and not between the power supply and the PCB (i think that between the PS and PCB should be more logical). I have also installed the fuse protection between the mains and the PS (at the end I thought i have to follow the advises of people who knows more about electricity than me even I dont see clear that this solution is the best). I don't know about other Arcade PS but mine has a fuse already (what was missing was the emi filter). I would like to install a fuse in the 5V and in the 12V lines.. but I dont know what kind of fuse (amperage?) As you see my cabinet would have 5 fuses, so I wouldnt say that I'm against the use of fuses :) |

I've just recently taken the old power supply out of the cab I'm mameing together with the jamma harness. If that's of interest to you then PM me and we can arrange something. (I'm in the UK) |
