Power Supply for Atari MegaFile 30 and 60
Built with modern components, these power supplies are more powerful, more efficient and generate less heat.
They are designed to fit on the original Atari power supply support. It fit in the same space. You can place the shield back.
​
They are ideal if you wish to swap your broken original Atari MegaFile PSU.
​
They work on with input voltage of 110V or 230V
High efficient switched power supply.
Low heat dissipation
No noise
Short circuit protection
​
Installation will require some soldering in order to disconnect the original PSU and reconnect the new one.
​
They are compatible with Atari MegaFile 30 and 60.
There can also be used in all Atari STF, STFm, STE and Mega ST
Here are more details on the specifications:
How to Swap your old PSU for a new own?
Swapping your old PSU for one of these new one require some soldering. Nothing too complicate, but never the less requiring you to have a solder iron, some solder tin and some experience.
The connector to the mother board will be used on the new PSU.
Safety warning first:
It is your responsibility to make sure you stay safe while working on your Atari and its PSU.
These PSU are intended to be used as a replacement PSU for Atari MegaFile. The new PSU MUST be fitted on the intended metal support you find in your Atari.
Do not use it without support and outside your Atari.
Do not touch the PSU when under power.
Unplug your Atari every time you open it.
Do not attempt to service this new PSU.
Here is what you will need. The pump and 3rd hand are optional, but could come handy:
Once you removed your old PSU from your Atari MegaFile, follow these instructions:
​
-
Unscrew all 4 screws holding the PSU on the support. Keep these screws and the plastic film.
-
With your soldering iron, unsolder the 2 AC cable. You apply heat on the solder pads and pull the wires from the other side
-
Do the same with the motherboard connector. Heat the pads and pull the wires. Do it one by one.
-
If you have a pump, heat the wire end of each wires and such the solder tin that may remain.
-
With the new PSU and the motherboard cable you just saved, insert each wire into the pad and solder them. Do it one wire at the time.
-
The 2 red wires go to pads marked 5V.
-
The 3 black wires go to the pads marked GND.
-
The bleu wire goes to the pad marked 12V.
-
-
Now the tricky bit is to solder the 2 AC wires on to the PSU. There is no order. You can solder them in any AC pads. Just see where they fit best. One is longer than the other.
-
Once all wires are correctly soldered, put the plastic film and screw the PSU on its support with the 4 screws you saved on step 1
-
Have a look at your work. The final result should look like one of these pictures (This is a previous version of the PSU):

​​FAQ:
​
Can I use these new PSU in the US?
Yes you can. These PSU will work with 110Vac and 230Vac. There is no switch to change. They will adapt.
​
Do I need to modify the case or the shield of my Atari MegaFile?
No, the new PSU fit within the space the original PSU was.
​
Do I need special tools to swap it.
Yes. You will need a screw driver, a soldering iron and soldering tin.
​
Do it come with the metal support, power switch and power socket?
No, you need a donor PSU. Only the PCB with the electronic is provided.
​
Is it compatible with Atari TT, Mega STE or Falcon030?
No
​
Can I use this PSU in my Atari STF, STE or MegaST?
Yes, you can. This PSU is designed for a MegaFile, but will fit in an Atari ST family (internal PSU).
​​
​​
Why did you not fit these new PSU with screw terminals?
Using screw terminals would have made the swap easier. But these screw terminals sometime fail and you end it with a live wire handing inside your Atari. This could damage your Atari or be dangerous to you.
