Right, I'll give you a little electricity 101 if you don't mind.
The power an appliance uses (in watts) is a product of it's voltage (normally 120v in the states, 220v in the UK) multiplied by the current it draws (measured in amps).
All electrical aplliances should have a rating on them, either stamped on or printed on a sticker, which will show at least 2 of those 3 values.
I believe in the states a household outlet will handle 15amps, or 1800w, while a UK outlet gives 13amps, or 2800w.
Generally, circuit breakers are designed to trip at 80% of the rated load, so a US outlet should trip at around 1440w, and a UK one at about 2240w.
Add up the wattage of all the equipment you want to plug into your power strip (if the wattage is not shown, you can work it out by multiplying the voltage by the current), add 10% as a safety margin to account for inefficient ballasts, transformers etc and so long as the power strip is rated the same as the outlet it is plugged into, and your figures are lower than the ones I gave above, you should be good to go.
Please make sure to double check your figures before you go to plug everything in, tbh the worst that should happen is you'll blow a fuse in your main panel, as long as none of the wiring in the house is bodged...
If you have any more questions, there's a great thread in this forum called 'Electrical Questions, if I can help someone I will' started by an electrician with loads of great info.
