The A1200 was considered the baby brother of the A4000 and was a very popular low-end machine of the early 1990's and is still popular among Amiga users today. It's probably the most common Amiga model still in regular use in vastly expanded forms. The A1200 came with a very poorly rated power supply (only 23w) so it was common practice to purchase third party power supplies or even use A500 power supplies (they are compatible) which have a higher wattage (65w?). Even a slightly expanded A1200 would often suffer from power problems.
