ATX to AT Adaptor Compatibility

A universal-fit adaptor - no need to check a model list.

Suitable for any standard ATX main power connector. This is a standard, industry-wide 20-pin or 24-pin ATX main connector on the PSU side, converting to standard P8 & P9 connectors on the AT side - it isn't tied to a specific brand or model.

PSU Side

Fits any standard ATX or Micro ATX PSU with a 20-pin or 24-pin main connector, from any manufacturer.

24-pin ATX main connector - plugs straight in
20-pin ATX main connector - plugs straight in

AT System Side

Provides standard P8 & P9 6-pin connectors compatible with any legacy AT motherboard requiring P8/P9 power.

P8 & P9 connectors for the AT motherboard
Optional switch and I/O shield add-ons available

Connector orientation matters. P8 and P9 connectors must be plugged in so the black wires sit side by side, together in the centre. A wrong connection can damage the motherboard - check the wire colours on both connectors before powering on.

Only thing to check: confirm your PSU has a standard 20-pin or 24-pin ATX main connector (not a proprietary or non-standard connector shape used by some OEM systems). If you're unsure, contact us with a photo of your PSU's main connector and we'll confirm.
