Suggests you're familiar with jump-starting an ATX power supply, though caution is needed to avoid damaging it. Use a multimeter, memorize the ATX connector pins and PSU connectors, and pay attention to voltage and current changes without an oscilloscope. For safety, consider getting a spare working PSU during testing—it's less reliant on your knowledge, quicker, and safer.
