My new case comes with an undoubtedly very cheap 400w power supply. It has a few molex connectors, about enough for my two hard disks, 2 cd/dvd drives and a floppy drive. However, I will have five or six fans to connect up too, all wanting molex connectors. Do I need a better power supply with more connections, or molex splitter cables, or is there something I'm missing here?
