Description



Power adapter ATX PC to terminal blocks 12V 5V -5V and 3.3V for LEDs, power supply of arcade terminals and/or all that could require a large and varied power supply + 4 PCB feet (also sold without PCB feet,please check my ebay shop if needed)



PART 1: Product Description



Whether you need 12V to power LEDs, 12V / 5V and -5V to power an arcade cabinet  or 3.3V to test an electronic tool, a PC power supply can give you all of that.



Everyone has an old PC no longer in use; and even if it's not the case, ATX power supplies offer the best Value for money as their cost and quality have nothing to do with what you can buy in the power supply market for the same price. It's possible to find a 300 or 500 watts used ATX power supply for less than 10 euros. This is perfect especially if you need a lot of power at a reasonable cost.



This ATX to terminal adapter turns any ATX PC power supply into a versatile power supply you can easily connect to using its multiple screw terminal blocks.



Features :



- Presence of an ON / OFF button
- 6 X +5V connectors on terminal block 16A
- 10 X GND connectors on terminal block
- 1 X -5V connector on terminal block (Caution, the -5V is not present on all ATX power supplies, if your power supply does not provide it, this output will not deliver any voltage)
- 1 X -12V connector on terminal block
- 4 X +12V connectors on terminal block
- 3 X 3.3V connectors on terminal block
- 2 "Power Con" connectors to easily connect a remote ON / OFF button if this adapter is not intended to be accessible (in this case put the integrated button on "OFF", and connect your new (any self lock) button using two wires to the two Power Con terminals )
- NO FUSE AS ALL PC POWER SUPPLIES already have built in fuses and so,they would just limit the amount of power you can access to without any more security!



The maximum usable power depends solely on your power supply (up to several hundred watts admissible and up to 16A/terminal)



- 1 X 24 pin ATX connector also compatible with 20 pin connectors for absolute compatibility with all ATX power supplies and optimal distribution of the electrical load.



PART 2: Examples and tutorials for use:



Example of connection with an old 350 watt power supply purchased for less than 10 euros on ebay:


The power supply has a 20-pin connector, 4 pins remain unused. Thanks to the keying system of the ATX standard, you can only  put the 20 pins connector  at it right place, otherwise it just doesn't enter.



The available current is written directly on the power supply, ie in this example the values ​​given on the label:



WARNING, this is only an example, adapt this calculation according to the data listed on your own power supply.


So remember this very simple formula derived from the law of ohm: P (power in Watts) = U (in Volts) X I (in Amperes)


I now have:


+ 3.3V X 15A = 49.5 Watts at 3.3V
+ 5V X 25A = 125 Watts at 5V
-5V X 0.6A = 3 Watts at -5V
+ 12V X 13A = 156 Watts at 12V
-12V X 0.6A = 7.2 Watts at -12V


And I have all these powers simultaneously, be careful not to exceed the power calculated, otherwise you could destroy your power supply (actually not really as ATX power supplies as far as I know all have an integrated surge protection but I prefer to warn you :)). 


PART 3: Security Information:


Attention, this adapter must not be in direct contact with a conductor (water, metal, etc ...), to avoid any risk of short-circuit. It can be placed on an insulating surface or fixed using its 4 holes M3 (diameter 3mm) located at each of its ends. The M3 format is certainly the most standard and allows to use PCB feet, spacers, screws, etc ...

rear part of the adapter:




I also propose on ebay a version sandwiched between two insulating plexiglass plates and mounted on fixing feet.
