PC Power Supplies

PC Power Supplies NZ

Power your build reliably with a quality PSU from Tech Supply Shed NZ. We stock modular, semi-modular, and non-modular ATX power supplies in a range of wattages to suit everything from budget office builds to high-end gaming rigs.

Choosing the Right PSU

Select a PSU with enough headroom above your system's total power draw. A 650W PSU suits most mid-range gaming builds, while high-end systems with powerful GPUs may require 850W or more. Look for an 80 Plus Gold or Platinum rating for efficient power delivery and lower heat output.

Modular vs Non-Modular

Modular PSUs allow you to connect only the cables you need, resulting in a cleaner build with better airflow. Non-modular PSUs include all cables permanently attached and are typically more affordable. Semi-modular PSUs offer a middle ground with essential cables fixed and optional cables detachable.
