Pico Box vs. Traditional ATX and Other DC-DC Power Supplies

Why Go Compact, Silent, and Smart?

When designing ultra-compact computing systems, the power supply is often the most limiting factor. Traditional ATX power supplies — and even many existing DC-DC converters — weren’t built for the new generation of small, silent, and efficient machines.

At Pico Box, we set out to change that. Here’s how our solution compares:

1. Size & Form Factor

Traditional ATX PSUs are large, rigid, and typically require a full-size case. Even the smallest SFX variants can be overkill for mini-PCs or embedded systems.

Other DC-DC solutions might offer reduced size but often lack integration, requiring external components, messy cabling, or additional cooling.

✅ Pico Box Advantage:

• Ultra-compact design fits seamlessly into NUCs, Mini-ITX, Thin Mini-ITX, and custom enclosures

• Direct 12V or 19V input support — perfect for tight spaces or mobile applications

2. Noise & Thermal Design

ATX power supplies rely on fans for cooling, introducing noise and dust over time. Even fanless models tend to run hot or throttle performance.

Other DC-DC modules often suffer from coil whine, poor EMI filtering, or inefficient heat dissipation.

✅ Pico Box Advantage:

Fanless operation with efficient thermal management

Silent — no coil whine, no moving parts

• Low power loss even under high loads

3. Power Efficiency & Load Handling

ATX PSUs are typically optimized for desktop PCs, not low-power, high-efficiency systems. Power draw at idle is often excessive.

Other DC-DC converters may lack dynamic power management or overload protection.

✅ Pico Box Advantage:

• Designed for low idle draw and stable performance across variable loads

• Smart protections: over-voltage, under-voltage, short circuit, and thermal shutdown

• Optimized for modern CPUs and SSDs with fast transient response

4. Cable Management & Integration

ATX systems come with bulky cables that are often too long and hard to route in small builds.

Other DC-DC solutions can require custom wiring or adapters.

✅ Pico Box Advantage:

Clean, modular cable design for easy routing in compact enclosures

• Compatible with standard ATX 24-pin and CPU power connectors

• Custom cable kits available for specialized applications

5. Use Case Flexibility

ATX power supplies are mainly for desktops.

Generic DC-DC modules are often built for industrial use with limited PC compatibility.

✅ Pico Box Advantage:

• Designed for a wide range of use cases:

• Mini PCs & HTPCs

• Embedded and industrial computers

• Edge computing devices

• Robotics and IoT systems

• Silent workstations and audio PCs

Conclusion: Power Evolved

If you’re building a compact, quiet, and efficient system, Pico Box is the power supply your project deserves. We offer the flexibility of DC-DC with the integration, stability, and quality typically reserved for high-end ATX systems — all in a footprint small enough to disappear into your build.
