PSU plug fuse issues

Lord Nicoll · February 17, 2017

Hmm, I had a 13 amp fuse in my RM850x's cable blow, which was bizarre since it shouldn't ever blow, there is another PC on the socket ring, and the I would guess the 13 amp breaker would go because if the current exceeds it for over 1 second it kills it, but the fuses I have are all slow blow fuses that need to be at 13 amps for longer than 1 second, and my PC still works. I put in a replacement fuse, and that too blew. I had used this cable in something else that only needed a 1 amp fuse, and then replaced it with that one, so far two fuses from the same packet blew, I'm starting to think it might be a bad batch but idk, maybe the PSU is doing something fishy, but it's not that old and works fine. I just stuck in a 10 amp one from a different manufacturer and it is working fine so far, would it be the cable's voltage drop maybe? It wasn't burned or warm in anyway, and is pretty beefy, although not as much as the one it replaced, it's shorter so won't have as much of a drop.

I just want to make sure that I read what you posted correctly. Are you saying that 2 13 amp fuses blew, but a 10 amp fuse did not?

Yep, I tested one of the fuse and it blew around 3 amps, I think they mis-labled a packet of them, I told the company but they haven't responded yet, I think it might be some cheap shitty Chinese one.
