Does your project need a little more umph than our wall wart adapters can supply? Why not give this a shot? This 2A "laptop brick" supply outputs both 5V and 12VDC and is terminated with a 4-pin ATX connector.
The ATX connector is a standard 8981 Series Power Connector, like the disk drive connectors in your PC. Adapters and cable assemblies are easy to come by at computer supply stores (also, check our related items) so you shouldn't have any trouble getting your project powered up.
Note: Only the pin next to 5V is grounded. The pin next to 12V is not connected (NC). Please refer to the picture of the bottom of the unit for more information. The AC cable for is included and works with 100-240VAC inputs via a 2-prong style plug.
If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

Recently purchased one of these to power a project I was working on. Needed both 5 volt and 12 volt so this fit the bill exactly. The unit is very well made and the outputs are both very, very close to the stated values. Also appears that there is very little ripple on the outputs. Had a little trouble finding a receptacle that fits the output plug but finally found out it is the standard for the power connectors on the old floppy drives.

I suppose I should have studied the picture a little better, however I have never seen an AC adapter come with such a short cable on the output side. The cable is permanently attached and the only way to resolve this would be to buy an extension cable with mating male/female molex connectors on each end.

I had hoped to use this to power a 12V DAC and a separate raspberry Pi. Unfortunately, I only get to choose one because there's only one ground. That means it outputs 5V OR 12V (not 5V and 12V) unless you're willing to daisy chain the ground connection.
Hi there! Both voltages share the same ground pin so both voltages are available.
