ATX Reset Adapter Description

This product is an accessory item for use with the PC Watchdog timers. It is used for adding a reset header (2 Pin) to PCs that do not have a reset header on the motherboard.

The ATX-20 & ATX-24 Reset Adapters for industry standard PCs consists of a 6" ATX power cable extension with a small circuit board attached that is enclosed in protective insulated plastic cover. A small portion of this board is exposed to allow access to a 2 pin header which connects to the reset header of our PC Watchdog timer products. It allows a PC to be reset by momentarily removing the Power Good signal from the power supply to the motherboard.

New Adaptor for Proprietary Dell PCs.

Effective June of 2011 we have released a version for Dell Optiplex and other models that use a non-industry standard mini-ATX connector. The Dell version is a 3.25" long assembly that also has a small circuit board with a 2 pin reset header.

The adapters can also be used by themselves to reset a PC if your cabinet has a reset switch, but the motherboard does not have a reset header.
