This still makes no sense... your (AC wall outlet to power supply) cords have fuses? I've seen cords with fuses, but never for a PC power supply. Very possibly... what country is the original poster located in? snip |

This still makes no sense... your (AC wall outlet to power supply) cords have fuses? I've seen cords with fuses, but never for a PC power supply. I have those fused wires and this unfused one... i'm not sure which belongs to which... but what i reported is how it happened... then that PSU that was connected when i had the accident (the firecracker sound)... well, i replaced the fuse in its cable (mains to PSU cable)... and it didn't run... maybe the firecracker sound came from the PSU after all... i don't know... but that PSU isn't working now... it was a high-end 550w PSU... i'm sorry it blew up 'cos it was pricey but i'm sorta glad it sacrificed itself... What brand was the 550W? If you leave it disconnected from AC for a few minutes and open it, you may see the damage. If a cap blew up you might see some paper-like foil loose in the casing, if the damaged cap isn't intact enough to be identifiable. It's vantec stealth 520w... a pretty nice one... i won't be opening 'cos it has a sticker that says warranty void if removed i find it strange that you say a normal cable doesn't have a fuse... 'cos i have those two PSUs and 3 cables... i can't remember which is which... two of them are 5amp-fused, one is not... as mentioned above about two fused ones, in addition, the unfused one gave me a nasty spark when i plugged it in so i gave up on it... i was lucky that it was the faulty psu that was connected rather than the good one when that happened... so, i decided i won't be using the unfused cable again. There might have been something wrong with the power supply to begin with, it shouldn't be drawing more than a fraction of an amp before the system is powered on. hmmm... what do u suggest i do |

BTW isn't the 4 pin connector keyed? I would have thought that it would be impossible to do what you did. Never underestimate the ability of people to get around things like that. I thought the same of PC133 memory, but my friend managed to not only plug in a module backwards but also lock the latches. Mobo and memory were OK (module got hot), but the PSU fried a transistor. |

Fuse is necessary because UK power board breaker is too
large for current capacity of power cords. US has no such problem because US does not use ring circuits to power wall receptacles and does not power those rings with 32 amp breakers. All this safety stuff on both sides of the pond have long been proven as necessary or unnecessary by decades of experience. One important circuit breaker is a 15 amp breaker on US power strips. Breaker often missing on many grossly overpriced protector type power strips and yet may be found on $3 non-protector type strips. No breaker on that power strip is, for example, why a kennel recently killed many dogs in the resulting fire. Reason for this breaker should not be confused with reason for fuse on UK power cords. larrymoencurly wrote: The fuse in the cord is probably a good safety idea that isn't used in all parts of the world, like North America. Is it a good idea to keep using that PSU that went ka-boom? Because if a filter capacitor was destroyed, the PSU could be putting out pulsating DC on one of the rails, and only the filter capacitors on the mobo are keeping the DC steady and allowing the PSU regulation to work. |
