Quote from: rkrenicki on October 14, 2018, 05:55:11 amI ran into the same issue with my ProII power supply. I replaced all of the caps, zeners, 5 transistors, several resistors, and the optoisolators and even the T2 transformer.. with no luck at all. I think one of the replacement transistors is bad, but I just got too frustrated with it and decided to go the ATX route. I literally just got the machine to boot with an adapter cable that I made up, but I would like a more polished product for sure.Count me in for one, Thanks!EDIT: Can you tell me the overall dimensions of the adapter? I am wondering if it along with the PicoPSU itself would fit within the stock power supply case..
Quote from: kamiboy on October 17, 2018, 10:05:53 pmWith all that free space left inside the PSU case I am sure you could even find room for the whole power adapter inside there. I am sure that if you remove the plastic shell of that thing it will take up even less room.Luckily all my original PSU's work, but if I had to do something like this I would prefer to have one cable coming out of my machine that plugs directly into the wall.

Quote from: leonk on November 14, 2018, 05:00:00 amI have a microATX PSU in my OG X68K; so I have an all internal solution. But even though it's a MicroATX PSU, there are a lot of components there to make sure power is clean, safe, with over voltage, over heating, etc. protection all there. Designing a Power Supply is not a simple task.So the choice of components that make up this PicoPSU adapter can either make it or break.Looking forward to see the solution.
Quote from: X-Col on November 20, 2018, 11:38:26 pmHi Matt,I got round to populating one of the version 1 boards you sent me and trying it on my ACE.I have 2 PICO PSU's and here are the results:The 'bootleg' PICO does not turn on when the power switch is pressed (continuous red light)The genuine PICO 120 will not turn off - with button in the off position the system seems to go into a shutdown loop (no red light)However, it works perfectly with a genuine ATX PSU! Any ideas?
Quote from: mattsoft on November 21, 2018, 03:45:06 amWeird. And just to confirm, your ATX PSU is plugged into the PCB in place of the PicoPSU? If so, then the inverter chip circuit is correct, but something about your PicoPSU is different. I'll do some more research and see if there are differences between PicoPSUs.
