Here is another. Thanks to Josh for the connections to get is going.
This is for the TDPS-750AB A unit that is 750Watts.
The main connector has +12V at 54Amps, +5V at 33Amps and 0V pins. I just soldered heavy cables onto the pins as I've not got a connector.
Josh sent me the info to get it working. In his picture, there are a couple of black wires going to an on/off swicth. (I just linked direct to0V and used the power switch.)
This is a nice flat power supply so your set could well sit on top of it. About 280x210x40.
One problem is the 2 fans installed are 12V at 6A!!!! They make great blower fans, or sirens if you prefer. And the power supply shuts down if the fans fail to get to speed.
There may be a hardware mod for this but my fix was a bit different.
Both fans were removed and the one with the longer leads replaced but turned 180 degrees so it now blows onto the main power supply heat sink.
First, I tried running the fan on 5V but it would not start. Then on 7V from en external power supply as 7V looks to be the minimum voltage to get it going to keep the supply alive. But the fan is still too loud. Next, running through various power resistors but that was not satisfactory. Another try was to use series diodes to drop the voltage, In this case, I have a bag of W04 bridge rectifiers so 3 of them in line dropped the voltage ok but they got hot and the fan is still too noisy.
The final fix I came up with is to cut the fan red wire and install a 12V 5W tail light lamp in series. This lets the fan speed up when the lamp is cold, then slows as the lamp heats. As the fan now slows down, the lamp cools so the fan speeds up again. This repeats so the power supply "breaths" but keeps working and has air to cool it.
There was a web site than came up with maybe a part of the circuit...
Another fan mod I hope to try is to add one of my PIC12F629 boards into the fan tacho line to double (or more) the pulse frequency to see if that can get the fan running slowly. And to increase the 12V to 13.8V too!
