What fuse for Medion Desktop computer?

Bosie

I am in the process of moving and unplugged my computer and also my Acer monitor, then having the 2 power leads in my hands:o One power lead says a 10 amp fuse and the other is saying a
15 amp fuse? Both are the original manufacturers leads.

But which lead is which? I've looked on both the Acer and Medion for any specs regarding fuses but nothing.

I don't want to blow the computer up?
Any help please

It certainly won't be a 15A fuse in a 13A plug, if for no other reason than that they don't exist!

A 5A fuse would be what I'd use for the PC and 3A for the monitor, but it doesn't really matter much if you put a larger one in.

If there's a catastrophic problem with shorting then you'd get (instantaneously) more than 13A of current, and your ring main Miniature Circuit Breaker would also trip.

If you have a look on the monitor, there should be a sticker which says what the power requirements are (and a similar stricker should be on the PC somewhere).

If you can't find the sticker, check the documentation for each one, it has to be in there (usually at the back).

If it's an LCD monitor, the power rating shouldn't much more than 60w - probably about 40w. If it's a big old CRT monitor, it could be 120w.

In either case, a 3amp fuse should be fine.

I must put my specs on, sorry it's a 13a fuse! Just to get a bit more techi if the power lead is thickish does the fuse be protecting that more than the computer itself?
It's also a long lead, a lot longer than I've had before.

The fuse is really only there to protect the mains lead itself. If the appliance needs a lower rating fuse, then it should have one built in to the power supply.

Officially, the only two "standard" fuses are 3A and 13A. That said, the IEC leads used on electronic equipment are often fitted with 5A fuses by the manufacturers.

A standard desktop PC is unlikely to have a PSU rated higher than about 500W-check it if you are unsure, it's marked on the casing. At 240V, this will draw around 2 amps. So a 3A fuse should be perfectly adequate. Should it blow (unlikely) then replace with a 5A one.
