We've got the power…supply.

From the looks of it, it is a fairly standard 12 V, 5 A power supply with your standard large capacitors and coils.

Whatever you do, don't lick your fingers and then touch the large black cylinder. You may be shocked to discover what 400 V can do.

Like the fan, this unit is made by Delta Electronics. They have named it ADP-60DFS, so as not to be confused with other, less-powerful power supplies.
