Jesverty DC Power Supply SPS-3010
The Jesverty SPS-3010 is a variable bench power supply offering 0-30V and 0-10A output. Its standout feature is a 4-digit LED display that shows voltage, current, and power in real time with high resolution (0.01V, 0.001A, 0.1W). It operates in automatic CV (constant voltage) and CC (constant current) modes, switching as the load changes. Users should note that the V and A settings act as crossover points between CV and CC modes, enabling responsive protection in mixed-load scenarios.
HLT ATX Power Supply Breakout Board Kit
This breakout board brings ATX power readily to a bench setup. It provides adjustable voltage outputs across commonly used rails: 3.3V, 5V, 12V, and a configurable 1.8V-10.8V via an ADJ knob. The board layout aligns with screw terminals for easy connection, and the accompanying acrylic case offers a compact, user-friendly enclosure. It’s suitable for small-scale electronics testing, embedded projects, and educational demonstrations where frequent voltage changes are needed without a full PSU enclosure.
Teyleten Robot XH-M229 24 Pins Board
The Teyleten Robot XH-M229 board serves as a 24-pin ATX power supply breakout adapter. It enables typical voltage rails—3.3V, 5V, 12V, and -12V—using a standard ATX supply as the power source. This module is well-suited for electronics labs and hobbyists who want quick access to core voltages for testing boards and sensors. Its design emphasizes straightforward power distribution with clear labeling and compatibility with common ATX connectors, making bench projects more efficient.
24 Pin ATX Power Supply Breakout
This breakout module offers quick access to standard voltages often used in embedded and hardware projects, including 3.3V, 5V, 12V, and -12V. It includes a power indicator and a switch to help regulate ongoing testing workflows. The design supports desktop chassis testing and prototyping where ATX rails need to be tapped without connecting a full PC build, aiding rapid iteration and debugging for engineers and makers alike.
Mustpoint ATX Breakout with ADJ
The Mustpoint breakout board includes an ADJ knob to fine-tune output voltages within 3.3V, 5V, 12V, and 1.8V-10.8V ranges. The ASSEMBLED breakout provides clearly labeled terminals corresponding to each screw terminal for easy wiring, and it ships with an acrylic case to protect and organize the setup. It’s suitable for bench demonstrations, educational labs, and hobby projects that require adjustable ATX rails in a compact form factor.
Onyehn 2pcs ATX Breakout Modules
These dual breakout adapters provide expedient access to typical ATX voltages including 3.3V, 5V, 12V, and -12V. They include power indicators and a switch for quick control during prototyping and testing. Designed for desktop or bench use, they enable quick distribution of ATX rails to multiple devices or test rigs without requiring a full PC power assembly.
Buying Guide
- Voltage range and rails: Identify which rails you need (3.3V, 5V, 12V, -12V, or higher). Some breakout boards offer adjustable outputs (ADJ) for tailoring voltages beyond standard rails.
- CV/CC behavior: For load variability, units with constant-voltage and constant-current modes help protect sensitive electronics. Check how the device transitions between CV and CC.
- Adjustability and controls: Coarse and fine knobs can improve precision when dialing in voltages. Consider whether you need a dedicated display for monitoring current, voltage, and wattage in real time.
- Enclosure and layout: Acrylic cases and compact boards reduce desk space and increase protection. Ensure terminals are clearly labeled for safe wiring.
- Connectivity: USB-C or USB-A ports can support fast charging or data devices. Verify whether you need charging capabilities beyond power delivery to the load.
- Compatibility: ATX breakout boards are designed to be powered by standard ATX supplies. Confirm connector types (20/24-pin) and rail availability to match your project.
- Durability and safety: Look for protection features such as overcurrent, short-circuit, and thermal protections to protect both the power supply and your devices.
- Size and portability: For mobile labs or small desks, pick a unit with a compact footprint and lightweight construction.
