Fuse in B3 power supply
Fuse in B3 power supply
The fuse in my power brick has blown. Does anyone know what type/rating the replacement should be?
Re: Fuse in B3 power supply
Nope.
However, as the PSU is rated 3A @ 12v we know that the primary side must be able to draw a minimum of 36 Watts as well. Here's the tricky part: because the PSU works with both 115 Volt and 230 Volt it should be able to function with a 160mA fuse in Europe but it needs to be 320 mA in USA.
Allowing a 20% overshoot you're likely looking at a 400 mA fuse. Which brings us to the real issue: if you are on a 230 Volt network there must be something terribly wrong with that PSU to draw more than twice its rating and you'll probably be better off getting a replacement PSU rather than try to fix it.

That is true I wonder what failed.
Gonna be hard finding 12V/3A, but at least I have a working cable
