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

Our Technician Answers:

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

Our Technician Answers:

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.

User M L Asked:

Hi, I am looking for a standard 12 volt/2 Amp cable with a barrel that Calle Baughurstis 5.5mm on the outside, and 2.5mm on the inside - center pin positive.

Our Technician Answers:

Hi ML. All the power supplies on this site come with the standard 5.5mm x 2.5mm barrel. They all center positive. So any of the 12 volt power supplies will match the connector that you need.

Why Order Your Power Supply from an American Company

This article discusses the benefits of ordering a 12V Power Supply Adapters you need from a company based here in the USA, versus importing direct from China.

Power Supply News


As a USA based manufacturer, wholesaler, distributor, or retailer, you are faced with some tough challenges and choices daily. Importing power supplies to power your products does not need to be one of them. While it is true that at first glance, buying a 12V power supply a little cheaper straight from China looked at closely, the deal may not be so good. Here is why. First of all, shipping from china is slow and unreliable, not to mention expensive. While many factories promise great price, and initially low shipping cost, it has been my experience that as soon as they have the business, they will start pumping the shipping cost higher and higher, even if they charge the same for the unit itself. The second problem with buying straight from overseas is the failure rate. It has been our experience that manufacturers will cut corners and cost as much as possible. If you do not know the factory, and have a long term relationship with them, they will use the cheapest possible material, lowest gauge wiring, thinnest plastics. This translates into an extremely high and rising failure rate. If you buy your power supply here in the US, if it fails, you can return it. Buying from china, you are out of luck as return shipping is super expensive. Once you figure in the cost of replacing failures, including buying and shipping them, the cost is no longer so low. Finally, it has been our experience is UL listing. If you need to have a UL listed power supply, both for the certification of your product, as well as for safety and quality, it has come to our attention that a vast portion of listing on Chinese wholesaler sites are issuing fake UL listing stamps. This means that the power supplies are of inferior quality, have a higher failure rate, as they do not comply with UL minimum quality standards. Worse yet, they are often stopped, seized by customs on entry, leaving you with the disposal fee, and possibly a fine. We have seen this over and over again. So, to sum it up, because of cost of shipping, importing, quality control, high failure rate, and fake UL listings, it seems like buying your 12v Power Supplies from a US based company, shipping from within the US, offers you the best protection, best lead times, and in the end, the best price.
