An adapter from Tripp Lite (now part of Eaton), a long-established IT/business-hardware brand.
- Converts PS/2 keyboard and mouse to USB
- From Tripp Lite/Eaton, a brand more commonly seen in enterprise IT supply catalogs
- Also sold in a combo cable-kit version (P778-006)

Buying tips
- If you need both a PS/2 keyboard and mouse working at once, buy a dual-port adapter (Perixx, UCEC, or the 4XEM dual version) rather than two single adapters, since some single adapters won’t run two devices from one USB port reliably.
- A passive adapter (no chip inside) can be hit-or-miss with older PS/2 peripherals; the Perixx PERIPRO-401’s built-in USB controller is the more consistent choice if a cheaper adapter fails to detect your keyboard.
- These adapters convert PS/2 to USB, not the reverse — check which direction you need before ordering.
