Sandy, Have you actually done a Current Test on this little lot?. I would beg to differ the <5A rating you give it. Just judging by the sizes of the flexes entering the plugs. What sort of protection do you have on this circuit?. Also having computer equipment on this sort of thing gives rise to Non-Linear Loads and overloaded Neutrals.
