What is the problem with the power supply? It is similar to notebook power adapters that Acer notebooks use. Just like a notebook, if it ever breaks, just bring the power supply down to Acer Service Center to replace. Much better than lugging a big computer down there if a full size computer's power supply breaks. Anyway, no additional cost as it is coverd by warranty. (For peace of mind, it is always a good idea to purchase the 2nd/3rd year extended warranty for new pc/notebook!)
