IBM PC XT AT PS/2 Clones Power Supply Load Tester (5150 5160 5170)
Price: US $68.00

The PC / AT / PS2 Power Supply Load Tester (also known as the AT PS Test) is a compact and convenient device which allows for rapid testing of computer power supplies utilizing the connector pinout standard defined with the original IBM PC. This standard was used in the PC, the XT, the AT, some PS/2 systems, and most clones up until around 1995 when the ATX standard became the norm. Power supplies using this standard (and thus compatible with the AT PS Test) are easily identifiable since they utilize two six-pin connectors (usually labeled P8 and P9) placed side-by side to supply power to the motherboard. See the product images for an example of what these connectors look like.

Such supplies will typically not start unless a minimum load requirement is met (this can be quite high – up to ~50% of full load.) Thus, the AT PS Test contains on-board load resistors to provide this load to the supply under test. It also provides status LEDs which indicate the presence of sufficient voltage on each of the rails as well as the presence of the ‘Power Good’ signal from the supply.

In addition, the AT PS Test has banana plug offering posts for each supply rail and jumpers to disconnect the on-board load resistors, allowing it to serve as a break-out box for testing power supplies with an external electronic load.

Note that there are many power supply testers on , but this is the only one (that I know of) which has the correct connectors for AT style power supplies and the only one which will provide sufficient load to turn one on. Newer (ATX) supplies need a much smaller load.
