Questions about this item

How can I confirm the PW400 delivers stable 12 V output after installation?

Measure the 12 V rail with a multimeter under load; it should stay close to 12 V if the unit is working as intended.

Which cables come attached to the PW400 and what must I source separately?

The unit ships with its fixed ATX loom; any additional PCIe or drive leads not already on the harness must be purchased separately.
