Be careful with that and make sure to add a fuse: https://www.cpcwiki.eu/index.php/Power_Supply_for_CPC_and_CPC_plus#Using_a_PC_power_supply

yup ive got a inline fuse holder and couple 4Amp fuses on my list of stuff to buy on friday!
...ill probably still run the CPC through my CC/CV buck converter with screen.. just so i can see current being pulled by the CPC...and for a 2nd level of current protection..

just an update.. havent plugged the usifac in since the PIO died... everything running perfect...
DDI-5 is running great (and seems the ram error on it is fixed! played rtype 128 fine lastnight)....both noels diag and etos ramtest work as expected
im gonna have to save up for one (or the M4 if they ever get built again!)...

not gonna try the usifac for a week... just to prove my point that its the usifac killing things on my board...

And it does not need to be an ATX PSU. This works pretty much:

It is an entry from german EBAY, but that is a pretty much standard 2 voltage power supply where someone soldered the correct connectors on.

I ordered on of those and they are actually the following
LACIE AC Power Supply
Model: ACU057A-0512

So this model:

For AU you should carefully check the part NO: 
  • AU: 710449A Purchase this power supply
Hope that helps and is much easier to obtain. Good enough to power lots of external cards.

ive been doing some PC repairs for years... so ive got a bunch of ATX power supplies i can use here....i have a nice 200w half size one here.. ill also be passing its input power to the LCD monitor (i could probably tap off the LCDs inbuilt power supply.. but.. id rather not!)

but thanks anyways! ill keep that in mind if i ever need it...

be sure to include some diodes and also some current limitors. You should not feed the 200Ws into the CPC. In case of a short it will burn to hell.

diodes? what for?... ill be using inline fuses for current protection... the board will only pull what it wants.. if it shorts the fuse should blow at 4amp..aswell as going through the CC/CV buck converter...should be plenty of protection... (i may even drop the fuse to 3amp..coz thats plenty enough current)

i was even thinking about using the 5VSB rail on this PSU that only supplies 2amp max.. which should be plenty to run the board and expansions...(ive never seen above 1amp with the expansions i have)

i also want to power the gbs8200 and esp8266 from a separate rail.. with its own inline fuse...

diodes for connecting something wrong way around ;-)

that wont happen if i solder the plug right the first time! :P
dont worry i check that with multimeter b4 plugging it in!

im going to just get one of these... save the stuff around wiring up fuses and a switch...just have to wait a bit longer for it...
