4 months / 4 power supplies

We are burning through power supplies at the rate of one per month so far.  I'd hate to have to pay out on power strip lifetime warrantees here.  You'd have to have Lloyds of London as a backer.  Luckily the power strips have, as yet, protected the devices on the other side.  Smoking electronics is not a pleasant smell.  And indoor fireworks is a sight I'd like to avoid in the future.
