to turn the PSU on!
I've just noticed that I accidentally edited that part out!!
Amiga 1200 is recapped and now to treat it to a brand new power supply, an ATX power supply with plenty of juice :o)
in this video I modify and "hack" a standard ATX PSU with switch, wire it to the commodore Amiga power plug therefore resulting in a higher power PSU which will handle anything you throw at it, from CD drives, floppy drives to Accelerator cards and other upgrades.

This is a cool project and I know I could do this if I needed to. Thanks for teaching us so much about electronics through your videos.
I did it in 1998 for my A1200, home made tower for Blizzard PPC, BVision and keyboard PC. ✌️😃
Good to see you got your A1200 back. I'm a bit surprised none of the modern Amiga suppliers offer more compact replacement Amiga PSUs.
This is true, I suppose this is easily done, but yeah accelerators are being made, all sorts of mods, but no PSUs.
Nice Job! We have to keep our Amiga's alive. I have owned an A1000, A500 but the two I have left are the A2000HD and A1200.
oh how lovely it is to se a woman making a nice guide like this, thanks a bunch for your effort
Nicely done and I think you should get rid of all the other wires hanging out of the PSU.
Here you are! Saludos!
good work lady .thank you
I am unsure if you did the picoPSU video yet but I just got my own 1200 and I need a psu, what would you suggest I do?
Thanks for sharing!
Great video! SO what ATX PSU i have to look for? Somebody said be careful with newer PSUs... so what should or can we use? I will power up my A600. It has it originally PSU but i don't have so much thrust in it :) Thanks
Brilliant.
very nice
Could you tell me where you got your supplies? Especially that plastic screw in connector at 10:04?
I thought you missed a step which is mentioned in the description. Also, 2 things. 1, You should crimp ferules over any wires that go into that type of wire connector ( frankly, I would have just stripped the wire back and soldered the connections and insulated with heat shrink but what ever.). And 2, you could cut any unused wires off at the circuit board ( if you aren't planning on using the powersupply for anything else). Just my 2 cents. And much neater too.
good job.
I did refurbrished original PSU by myself, only old caps changing, that was it
Hi! Do you know anyway to have a internal PSU on 500? Thanks!
Yes, some people have done a mod using the Pico PSU.
I am mid-restore of my A1200. So far, I have got an Amigakit CF hard disk, a Gotek USB and I am about to take delivery of a an ACA1233n and mini-mys ps2 mouse adapter.
A few peripherals, like my original A600 mouse was buggered and only worked horizontally, if at all. I am dreading issues with the PSU, just because it seemed to have been given the classic Commodore build 'quality' touch. Is this still a recommended upgrade?
Nice! your A1200 is coming along then.
Well i'm wary of this after reading MVG's comment but i've been using mine still and to this day.
I've been sitting on that PicoPSU thing, I have a plan to do a video creating it but really hate goofing around with power projects to do with the Amiga out of fear. But now I have a spare goofed up A500 I can test on at least so I think i'm going to bring that forward.
An update on my mouse problem which might offer help to those who are also suffering issues. After some quite scary quotes for repair, I began to dismantle my A1200.
After taking the shielding off I noticed my motherboard revision was the one with a seperate daughterboard mouse controller card. I looked all around the port and saw no visible signs of burnout or damage and after removing it from the mainboard, I spotted LOTS of oxidising all over the pins which sat inside the plastic connector! I took a sharp blade and removed and cleaned it up and the mouse works perfectly again...
So, in short, if your amiga peripherals are behaving erratically, start investigating where the inputs travel using the cheapest diagnotic tool you have... Your eyeballs! :D
Muy buenas, te escribo por primera vez en tu canal, permite decirte de que me encanta, te he encontrado por casualidad porque estaba buscando algún tutorial para poder conectar una nueva fuente de alimentación para mi Amiga 1200 con BlizzardVision y BlizzardPPC/060, le implementé una nueva unidad Gotek y un disco SSD conectado a la IDE de la placa, obviamente me daba problemas de potencia, pues la luz verde de Power parpadeaba y no arrancaba.
Tengo ciertas dudas pues no estoy muy familiarizado en este campo, que fuente de alimentación me recomiendas?puedo usar la conexión de una fuente de Amiga 500? o me recomiendas que use la de un Amiga 1200 como tu bien usas en el vídeo,perdona por si se me ha escapado algún detalle del vídeo ^_^
Muchas gracias por toda tu atención y bueno ya estoy suscrito a tu canal que me encanta!! Felicidades.
Primeramente, lo siento porque mi español no es bueno jaja, tengo que practicar :o)
Muchas gracias para tus palabras sobre mi canal.
Sí, puedes usar la conexión de una fuente de alimentación de la Amiga 500 para una Amiga 1200, es el mismo conexión. A veces algunos utilizan el fuente de alimentación de la Amiga 500 para la A1200 porque tiene mas poder. Pero necesitas más que esto para tu Blizzard PPC, BVision y más. Un buen ATX power supply. no necesitas más que 300W. Puedes usar un fuente de alimentación como esto tambien: www.nightfallcrew.com/15/06/2014/commodore-amiga-500-full-replacement-power-supply/
Voy a hacer un “pico PSU” para mi Amiga 1200 in el futuro. www.quietpc.com/images/products/picopsu-160-xt-acdc-components.jpg
MsMadLemon Muchísimas gracias por toda tu ayuda (^0^), no te preocupes, tu español es bastante bueno, seguiré viendo tus vídeos tutoriales y te informaré sobre los avances que consiga.
Un saludo muy cordial y gracias.
Are the amiga PSU's that bad? My 1200 is running a 4gb compact flash and an ACA1221 (fully unlocked) on the original PSU and I have not had any problems so far, I did not know it was even a thing! What warning signs should I be looking out for that its time to mod an old ATX psu?
you're probably pushing the PSU, it's highly recommended that you get a higher wattage one if you're using the ACA1221, though i have an ACA1233n so i'm figuring it's going to use more.
Signs. Well if your Amiga crashes a lot then thats a sure sign of it not getting enough juice.
I had the same thing on my 4000 (Before it got sold for the $$'s :(
It had a Cyberstorm 060 (MKII) with the Cyberscsi, I wanted to use a SCSI to IDE Bridge with a CF adapter, but the system was guru'ing on boot and rebooting, but was fine without the cyberscsi.
So for Dave, Power supplies do lose capability the older they get (caps wear out etc).
Lemmings :D i remember them!
My worry with this. Is that PSU going to cause any issues with the Amiga? I am tempted to do something similar.
I can understand, so far it's working fine for me, but i'd advise to get a decent quality PSU. I am going to attempt the pico PSU in future.
I've been using the type of power supply (different brand and power) and it has worked great for about 10 years, and another one before that one.
But if you start to upgrade the Amiga with all kinds of stuff then you could fry the incoming traces because of too high current.
These PSU delivers ALOT more than the old ones. ;)
be careful with an ATX powersupply. newer ATX ones - can't deal with quick changes in load on the +5V line. I fried my RapidRoad USB this way,
AmigaKit used to sell refurbed ATX supplies but no longer due to this.
Thanks for the heads up, I had no idea about this.
What would be best to use instead? An AT PSU? or?
Where can I find more information about this and how to select an ATX where this is not a problem?
I have a ATX PSU on my 2000 and another ATX on my 500's..Yes running 2 A500 on 1 ATX with no problems at all... My friend now wants me to mod a ATX psu for him as well..
All i can say ATX psu are the way to go.
Strange, I'm running A1200, PPC 333Mhz, 256 Mb ram, fast ata, hdd, mediator with GPU, LAN, USB and I have no issues with ATX PSU.
will this work on commodore C128 ?
No! not at all... the C128 does use the square Din but the pinout and voltages are different.
Next time with the wire connectors tin the leads first. But great video !
Good point! Thanks!
When using an ATX it would be best to gather all the +5V, +12 and -12 together to use the full power the supply can provide. It requires soldering them all together and takes more time, but you can get much better power this way. -Acill
Just to clarify, NOT all together in the same line, I mean all 5V in one bundle, all the Grounds in another bundle, all the +12 in another and so on :)
Hahaha I got what you meant in your initial comment and a good point you make :o)...
What an interesting mess that would make, putting all +-12 and 5v lines all together along with ground into a single mega powerful rail ;o)))
There's actually not much point in increasing the wiring capacity beyond what the Amiga power lead itself has. You are limited by the weakest link.
I am not sure that is a good idea. The Amperage of ATX psu is great and a small spike could easily roast the machine. Most ATX conversations install Amp limiters to protect the machine.
I guess this won’t work on an Amiga500?
Yes it will, A500/+ A600 and A1200 all use the same power supply.
Name of the game at 12:17?
it's a demo called 'Avenger Megademo'
Your Lemming is gonna get cold.
I'm in the process of building a new power supply for my A1200. I'm going the Pico route. I've got an original black A1200 power supply (bought black to match my new A1200 case from www.a1200.net) that I'm converting. I'm using Ian Stedman's picoPSU adapter (can be found at www.ianstedman.co.uk/Amiga/designs/Amiga_ATX_Adaptor/amiga_atx_adaptor.html) and an authentic picoPSU-90. Looks to be a fun project. Love your solution as well.
shells should not be ignored, it should be connected to ground
Kinda interesting in a way :)
In what way? :o)
In a power supply kinda way :)
cool, nice to know :o)
Im here for the games :P
So you keep saying repeatedly, trying to convince ourselves are we? hmm? :op
Great video, but i really wouldn't recommend a PSU over 250W to use on the Amiga, newer and larger supplies have a minimum load needed to power the rails, and its usually far higher than the Amiga can put on it, and has been stated by MVG can kill your Amiga.
Modern ATX is about 1A on +12V and about 300ma on +5v.
Brian White I have a 210 watt dell psu, and it states +12v has 12.0A, -12v has 0.5A, +5v has 15A, and +5vfp has 2.0 amp... what is vfp?
That new power supply seems to be cheap and you should solder wires...
