Unfortunately your power supply was specific to the 4400 and 7220. It resembles an ATX power supply, but with completely different connectors. Most likely it also has different dimensions, although I've never checked. Are you sure the PSU is dead? Obviously if it died with a shower of sparks out of the fan opening it will be, but I've also had the motherboard and battery causing them not to start. A simple check is the pull the soft start lead and plug (P9 on PCB), and short the white and black wires on the plug together. If the PSU starts, it's OK.
