Perixx PS/2 To USB Adapter
Best for users who want a built-in USB controller in a PS/2 to USB adapter. The PERIPRO-401 supports PS/2 devices through a single USB 2.0 port, making it suitable for desktop and some notebook setups. It also works with PS/2 on KVM switches.
UCEC PS/2 to USB Adapter Converter
Best for broad compatibility with PS/2 keyboards and mice on Windows, Mac, and Linux. The dual PS/2 ports (purple for keyboard, green for mouse) support straightforward connections through a USB port, fitting general computing setups.

Buying Guide
What to check before buying a PS2-to-USB adapter:
- Device compatibility: Ensure the adapter supports your PS/2 keyboard or mouse model and your operating system.
- Number of ports: Decide if you need a single adapter or a multi-pack for different devices.
- Built-in USB controller: Some adapters include a USB controller for more reliable signal translation.
- PS/2 color coding: Purple is usually keyboard, green is mouse; verify labeling for easy connection.
- Clipping and build quality: Look for sturdy connectors and durable housings to avoid wear over time.
Compared to older PS/2-only setups, these adapters provide plug-and-play USB connections with minimal setup. For KVM switches or mixed environments, the adapter with a built-in USB controller may offer the most reliable performance. If budget is the priority, multi-pack options can reduce replacement costs. Always verify that the specific device and OS support PS/2-to-USB translation to avoid compatibility issues.
