User Kit Autry Asked:

Had a fire 3 yrs ago and just retained a couple of 500 GB External hard drives but, no AC adapters. The first one is, a SeaGate DeskTop 12V output, 2AMP 3.0 USB. P/N 9ZH9P77-RAA. With an, SS computer plug on it The second one is a Western Digital, MDL: WD5000D032-000. I know that it is 12V But not sure if it is a 2 AMP or a 3 AMP. it has, what appears to be, 3 plugs. One computer and , 2 fire wire. The DC plugs are differant size per each model or P/N. If you could help me figure this out? it would greatly appreciated and, I could retain some of the files that were thought to be lost in the fire. Thank you for your time. KA

Hi Kit. As far as the Amperage and Voltage of power supply, it is simple. They are both 12 Volt, so you can use the same adapter for both. In this case, since one is 2 Amp, and the other 3 Amp, you will use the higher rated one. The 3 Amp, which is the maximum load you can put on the power supply, will work for both. As far as the connector, all our power supplies come with a standard 5.5mm x 2.5mm DC connector. You will see if this matches your device.

User Tom Buehrer Asked:

I am looking for a ac-dc 12v power adapter for a wall mounted Encore AM/FM Cassette recorder/player Model 7677 by Electro Brand. This unit was in a Park Model home that we just purchased, the unit seems good but is missing the 12v power adapter. I believe that it requires to be center pin +, and I think according to what info I have is Part no. 78w. What greatly appreciate any help that I can get, so that I can power up the recorder and check it out. Any brand of adapter is probably OK, as long as the pin diameter and polarity is correct, I believe that the outside diameter of the connector would be 5mm, Many thanks, Tom

Hi Tom.. It looks like you need a basic 12V Power Supply. For a load of 78 Watts, you will need to divide the wattage by the voltage, to find out the amperage. In this case it is 78 divided by 12, giving you 6.5A (Amps). You always round up for amperage. So the power supply you need is the Standard or UL Listed 12 Volt, 7 Amp, power supply.

Power Supply News and Information

Understanding Amperage, and Selecting a Power Supply.

This article addresses a commonly asked question, what does amperage mean, and how do I select the correct amperage power supply for my device.

Power Supply News


Amperage is an accurate measure of the amount of current passing any point in an electrical system (wire), at any given moment. If voltage can be considered the size of the the electrical flow, the Amperage is the speed of the flow; how many electrons pass a certain point in the wire per given number of seconds. When choosing the Amperage of a 12 volt power supply, it is important to realize that the Amp rating of the power supply represents the highest (maximum) load that it can handle. This means that a 12 Volt power supply rated at 5 Amps, can handle any load up to 5A, or 5000 mA. It would be safe to use that device for any smaller device or load, such as a 1A router, or 2A DC motor. It is not recommended to put a higher load on a power adapter than it is maximum rating. This will shorten the life of the unit, lead to quick failure, and possibly be a hazard. In order to find the maximum wattage of a power supply, you multiply the volts by the amps. For example, a 12 Volt 5 Amp power supply would be 12 x 5 which is equal to 60 watts. This means that the power supply can handle any 12V device, rated up to 60 Watts.
