Yes, Like Nigel sais, try going to an electronics shop nearby and show them your old fuse.

You can also order it online.

Fuses are meant to protect against fire and other things that can happen when the supply is shorted, they are NOT meant to protect the supply itself.
When a real short does occur it's very likely the supply will ge gone before the fuse pops.
If you want to protect the supply you'll have to add an electronic current limiter.

 

Sorry, I thought I had filled out my profile. I'm from Australia.

I took the fuse into the local electronics store, and the guy said it was a slow blow fuse BUT he wasn't 100% sure because the physical appearance of the original was different from the slow blows fuses they had in stock. I recieved an email from Jaycar (they sell the same PSU) today and they say that the 'T' means slow blow fuse, but they did not say whether 'T' was the same as 'S'. I replied asking that question and am waiting for their reply.

Assuming, of course, that it is a M205 fuse (5x20mm)

 

Yup, they are M205's. I have a box of slow blow fuses here of the correct rating. I think I was just confused about the physical appearance, and I didn't want to put a wrong type in. Thanks.
