Power Requirements
The normal HDD or SSD power consumption:

• SSD < 3W
• 2.5 HDD 3 ~ 5W
• 3.5 HDD 5 ~ 10W

Depending on the disks type and number, the Taco can be powered in the following options:

• Option 1: Dc Power
  Powered via the 12V Dc Power Jack. Compatible with standard 12V Dc adapters (5.5 x 2.5mm, center positive). Supports up to 5x 2.5" HDD or SSD.

• Option 2: ATX PSU
  Powered via the 12V Dc Power Header. Suitable for PC enclosure installations. Most ATX PSUs > 100W meet the power requirement. An ATX floppy-type cable is required.

Availability
Radxa guarantees availability of the Radxa Taco until at least March 2036.
