As a result of the switching power supply design, some ATX power supplies require a load of some sort to be connected to the +5V output in order for the other outputs (like 12V) to work properly. Rather than go into details, I'll repeat Roxy's suggestion to search on the terms "prusa i3 and ATX power supply", or "rep rap printer and ATX power supply", etc. It doesn't take long to find people who discussed problems with using an ATX power supply and how adding a power resistor to the 5v output got them working.
