Description

This product is used for adding a reset header (2 Pin) to PCs that do not have a reset header on the motherboard.

The ATX Reset Adapter 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 products. It allows a PC to be reset by momentarily removing the Power Good signal from the power supply to the motherboard.

This adapter can also be used by itself to reset a PC if your cabinet has a reset switch, but the motherboard does not have a reset header.

Some older Dell PCs have the standard ATX connector on their motherboard but their pin-outs do not conform to the ATX pin-out specifications. Before you order or use this product check the pin-outs and color code in these tables to see if your model adheres to the ATX specification.
