How safe are 10-way adapter sockets?

[Angilion]

I have a large bedroom and only two single mains sockets, both on the same wall. At present, I have a 4-way adapter strip in each one. I want to move my desk. If I do, that will take my PC a little too far from the wall with sockets on for a 2m extension strip.

I could hire someone to put more sockets in, but that's expensive and I need a lot of sockets.

I'll be running this lot:

PC
CRT monitor
Printer
External HDD
Headphones
Alarm clock
Three floor lamps

A 10-way adpater with a 3m cable would do the job, but is it really that easy?

Sounds like a bad idea to me. Having only two single sockets is a bit odd, how old is your house wiring. What is the wattage of the floow lamps and PC PSU, they will be the biggest consumers of power. What amp fuse is the extension cable supplied with?

The house was rewired 10 years ago, just before I bought it. It has new sockets and there are three circuit breakers in the meter cupboard downstairs (mains ground floor, mains 1st floor and lights?)

Total wattage of the floor lamps is 56W, I think - two 18W tubes in one and 10W low-energy bulbs in the other two.

PC PSU is 450W, though I've no idea what it actually pulls from the wall in use.

The adapter is rated for >3KW (13A at 240V), so I don't see that being an issue.

As others have said, it's not really the number of appliances you have, but the total current draw. All those appliances are relatively low-power, so their total power draw will still be far less than (say) a 3KW fan heater.

Given that some of it is sensitive equipment (like the computer), you would want to make sure you have surge protection, but other than that don't fret about it. Just make sure you don't daisy-chain items like space-heaters, kettles and other electronic heating devices in there.

That's what I was thinking, but I was concerned there was some sort of problem that I was missing because of my scanty knowledge of how it works.

I already have separate surge protectors, ones that go in the socket, so I should be able to use the 10-way with one of those in the same way that I'm using the 4-ways with them now.
