Who it fits

Key specs explained

Weight: 1.76 ounces

This lightweight design allows you to mount the adapter easily inside your case without adding significant bulk. You can place it in tight spaces without worrying about structural stress or cable strain. This low mass is ideal for users building compact systems or those who prioritize minimal internal clutter. It ensures the board does not interfere with airflow or other components.

Dimensions: 7*3cm

The compact footprint of 7 by 3 centimeters means you can install the unit anywhere without blocking fans or drive bays. You benefit from flexible placement options within your chassis. This small size helps you maintain a clean cable management layout. It is significantly smaller than standard power supply units, making it a discreet addition to your hardware setup.

Connector: 4-pin Molex main power

This connector type allows you to draw power directly from your primary power supply. You can easily integrate the secondary unit into your existing power distribution. This standard interface ensures compatibility with most older and many newer power supplies. It simplifies the setup process by using a common connector rather than requiring proprietary cables or complex wiring modifications.

Connector: 24-pin ATX

This connector links the secondary power supply to the motherboard, ensuring synchronized operation. You can power additional components like video cards or cooling fans through this secondary source. It provides a standard interface for main system power. This setup allows you to manage power distribution effectively across multiple units, supporting complex builds that require more power than a single supply can provide.

Design and build quality

The Thsion Dual PSU Sync Adapter is a small solid-state PC board. According to the listing, it measures 7 by 3 centimeters. This compact footprint allows you to install the unit easily in tight spaces within your case. The board does not generate heat during operation, which helps optimize power distribution without adding thermal load to your system. You can mount it anywhere without worrying about airflow interference or physical obstructions.

The device weighs 1.76 ounces. This lightweight construction means you do not need heavy-duty mounting hardware. You can secure it with standard zip ties or adhesive pads. The low mass reduces strain on cables and prevents the adapter from pulling on connectors. This makes it suitable for builds where cable management is critical and space is limited.

The layout is straightforward. It features a 4-pin Molex connector and a 24-pin ATX connector. These interfaces allow for a plug-and-play setup. You simply connect the primary power supply's SATA connector and the secondary power supply's 24-pin connector. The solid-state design ensures reliable synchronization without moving parts. This simplicity means you can set it up quickly without complex wiring or additional tools. The finish appears to be a standard printed circuit board, typical for internal computer components. This utilitarian design focuses on function rather than aesthetics, keeping the unit out of sight while delivering stable power to your secondary components.

Setup And Everyday Use Guide

Setting up this adapter is straightforward. You connect the primary power supply’s SATA connector to the designated plug on the board. Then, you attach the secondary power supply’s 24-pin ATX connector to the other available plug. The device uses a 4-pin Molex connector for the main power input from the new source. This plug-and-play design means you do not need complex configuration software or additional drivers. The solid-state PC board is non-heat generating, which helps optimize power distribution without adding thermal load to your system. Once connected, the unit automatically synchronizes the power supplies. When you turn on your computer and activate the primary power supply, the adapter signals the secondary unit to start. This allows the secondary supply to power additional components such as video cards, hard drives, and cooling fans. The small size of 7 by 3 centimeters makes installation easy in tight spaces. You can mount it anywhere inside your case without worrying about cable strain or bulk. The 2-pack quantity provides redundancy or allows you to manage multiple dual-PSU setups if needed. Daily use involves no further interaction. The hardware handles the synchronization process silently and continuously. This simplicity ensures that your additional hardware receives stable power whenever the main system is running. The design focuses on reliability and ease of use, making it suitable for users who need to expand their power delivery without complex wiring.

Before you buy this adapter

You need to verify that your primary power supply has an available SATA power connector. The adapter relies on this connection to detect when the system is on. You must also ensure your secondary unit accepts a 24-pin ATX signal for activation. This setup works best with dual power supply configurations for high-end builds. You should check cable lengths in your case. The board is small, but routing two power connectors requires space. Keep the unit away from direct heat sources. The listing notes it is a non-heat generating solid-state board, but good airflow helps longevity. This adapter is a niche tool. It does not replace a standard UPS for power backup. It only synchronizes two PSUs. If you need surge protection or battery backup, look at dedicated UPS units. This product is purely for hardware synchronization. Make sure your motherboard supports dual PSU setups if you plan to use both simultaneously. This is a simple plug-and-play solution for specific enthusiast builds.

Check before you buy

• Verify primary PSU has free SATA power connector
• Confirm secondary PSU accepts 24-pin ATX trigger
• Check case space for dual PSU cables
• Ensure motherboard supports dual PSU configuration
