PicoPSU 160W 24Pin ATX Mini ITX Power Supply - Compact 12V Adapter

In this review of the PicoPSU with Cable DC 12V 160 Watt 24Pin ATX Connect, the bottom line is simple: it is a compact, purpose-built power module for mini-ITX builds and lightweight server or mining rigs that need a reliable 12V input. The reviewer found it best suited to users who want to replace bulky PSUs with a tiny adapter that plugs directly into a motherboard ATX connector and delivers up to 160W with short-circuit protection. For small form factor projects where space and simplicity matter, this PicoPSU is a practical choice.

Key Features

• Compact 24-pin ATX connection: Plugs directly into the motherboard ATX socket to free up case space and avoid a full tower power supply.
• 160W output power: Provides a stable 160W output suitable for many mini-ITX systems, light servers, and 12V-only applications.
• 12V DC input compatibility: Accepts an 11.4-12.6V DC input range using the specified 5.5mm x 2.5mm barrel connector to work with common DC adapters or external supplies.
• Short-circuit protection: Built-in protection shuts down output in case of a short, protecting connected components from damage.
• High efficiency: Designed for power efficiency of at least 85%, which reduces heat and energy waste in compact builds.

Who It's For

The PicoPSU is aimed at DIY builders, compact mini-ITX system integrators, and small server or mining setups that need a 12V DC solution and minimal internal space usage. It is ideal when you want a clean internal layout without a standard ATX PSU and when system power draw stays within the 160W envelope.

It is less appropriate for high-end gaming rigs or systems with multiple high-power GPUs and large CPUs that exceed 160W combined draw; those users should opt for a full-size PSU with higher wattage and multi-rail protections.

Pros & Cons

Pros

• Very compact form factor that plugs into the 24-pin ATX connector, saving case space.
• 160W continuous output is enough for many mini-ITX desktops, light servers, and crypto miner controllers.
• Built-in short-circuit protection adds a safety layer for small builds.
• High efficiency (>= 85%) helps lower heat and improve power use in constrained enclosures.

Cons

• Limited to 160W and a single 12V input range, so it is not suited for high-TDP builds or machines that need additional voltage rails.
• Depends on an external DC adapter with a 5.5mm x 2.5mm plug, which must be chosen separately and rated for the full current.

Our Verdict

The PicoPSU 160W 24-pin ATX module is a pragmatic choice for mini-ITX builders and small server or crypto controller projects that need a compact 12V solution. It delivers reliable 160W output, short-circuit protection, and good efficiency, making it excellent value for applications that stay within its power limits and prioritize space savings.

Frequently Asked Questions

Can this run a mini-ITX desktop with a low-power CPU?
Yes. For low-power CPUs and modest storage or integrated graphics, the 160W output is typically sufficient when total system draw stays below the rating.

What DC adapter plug size does it require?
The PicoPSU requires a barrel connector with 5.5mm outer diameter and 2.5mm inner diameter, and the adapter must supply up to 21A at 12V for full power.

Is there protection against shorts?
Yes. The module includes short-circuit protection that will shut down output if a short is detected, helping protect your components.
