The motherboard lacks a CPU power connector.
Never encountered such a device before. You might want to construct your own if you're willing. It involves trimming your existing Fujitsu power supply cables. You'll require a reliable multimeter, a 24-pin ATX extension, cutting tools, heat shrink tubing, solder, and a soldering iron. Be prepared with patience and a touch of luck. Start by using your multimeter. Place the motherboard inside its original protective case along with the original power supply. While the computer is running, measure the voltages at each connector pin on the motherboard using the power supply. Record which pins correspond to which voltage readings. Once confident in your mapping, remove the male end of the ATX extension, detach the motherboard power connectors from the supply, and align the wires from the Fujitsu connectors with your mapped ones. Secure the connections, solder them, then seal all joints with heat shrink tubing before powering it up. Hopefully, the lights will come on smoothly—just watch out for smoke if anything goes awry!
It seems like you're planning to upgrade your system, so you might need to purchase a new motherboard.
