mac mini and a bit of peculiar behaviour...

'Lo all.

Having become a computer audio ist in the last year I have to say it's quite an excellent way to play all my music; into a decent dac and actives and I'm happy!

Except I'm not now. Having set up the mac mini as a music player only I expected it to work forever, as it were, on such a light load.

Now it keeps blowing a fuse, literally, every ten or twenty minutes.

It worked fine for a year and nothing has been added or altered, but now it blows the adapter fuse within an albums worth.

I know nothing about them, so any ideas most very much welcome.

Thank you and cheers.

Arthur, what sort of music are you playing through it?

Nothing but the very best Greg.

Bach concertos the first and second time it expired.

I assume this is a Mini of the older generation, with the external PSU? Can you swap out the PSU, see if that's at fault?

Also, double check the fuse value.

Lo Chris. It is indeed the older generation, unfortunately I don't have a spare power supply or even know anyone else with a mac. The fuse that blew first was a 3 amp but I've sinced wiggled a few wires and used 5 amp ones.

I'd be worried by this behaviour. I believe the power adapter is sealed and just supplies DC to the computer.

Suggests the power supply is either 85w or 110w, so you should be good with a 0.5amp fuse. Blowing a 3 amp suggests a fault. I'd get a replacement for it.

eBay prices are around £25 for a replacement if it's the 85w model. Don't just keep upping the fuse, that's how to burn your house down.

I'd agree with above - seek out a new power supply.

If you'd been local to me, I could have lent you one to try, but it seems that you're "oop north", and I am "darn sarf"

Gents I think you may be right, apparently it's not unknown for the power supplies to fail and or wobble. I'll get a new one and hope it's that. Cheers all.

Do not increase the fuse value that is asking to burn out the entire unit.

Hmm...it seems I should learn more about electrikery.
