I Use something like this, http://www.ebay.com.au/itm/HPM-POWER-BO ... tem588ffbc you can pick them up from computer part shops cheaper than this,recyclers even cheaper This will also give you a 20amp overload instead of 10, most cheap boards when they heat up will switch overloads at 8 or 9 amps. This can be a problem if you are running lights and sound from 1 socket.
