Here are 4 simple 12V power supply circuits with output voltages around 12V. First power supply circuit is built with BD139, one zener diode and a few passive components. Each of the schematic is very ...

This ac to dc power supply can output 5A in continous operation and 12A peak current. This kind of dc power supplies uses a PCB so you can use two case types for IC1, TO-220 or TO-3. The regulation of ...

Seasonic has just upgraded its GPU cables for some of its power supply units with upgraded H++ connectors that are compliant with the new PCIe Gen5 and ATX3 standards. The new 12V-2x6 power connectors ...

At eTeknix we take the power supply testing procedure very seriously. For all power supply reviews we used a variety of Chroma machines and other digital power machinery provided by Enermax in their ...

We don’t often talk about power supplies, but Intel’s new ATX12VO spec—that’s an ‘O’ for ‘Oscar,’ not a zero—will start appearing soon in pre-built PCs from OEMs and system integrators, and it ...

In order to put some extra power to use (I'm paying for the electricity whether I use it or not), I recently picked up an FPGA-based Bitcoin miner from the Agora. It has a 4-pin Molex inlet, just like ...

I am an American living in Switzerland and have no problems with most of my equipment running off a 240-120V transformer. Everything except some electronic equipment which also has its own 12V ...
