Today I finally had the time to apply ATX Watchdog in my setup. I wanted to migrate my DVB-S2 server to low power system. So my setup consists of a PI4 CM Lite 8GB, CM4 IO Board and a quad tuner DVB-S2 PCIE-X1 card (TBS 6905) overall consuming less than 36W. After assembling my proof of concept and finishing software setup, I wanted to put everything in a 1 U server rack. ATX Watchdog enabled me to easily use an Flex-ATX power supply and power button. I had some problems after connecting my PCIE tv card. System shutdown after some seconds. Looks like the power drain was too high. However I found a workaround by not using the power cable supplied connecting ATX-Watchdog to CM4IOB and instead I connected the floppy connector from the PSU directly to CM4IOB. Now it's working for me as expected. Another thing is the orientation of the ATX-Watchdog ATX connector. It's impossible to mount the CM4IOB in a case and make use of the back ports. In my case it would have been better to change orientation by 180 degrees. This way, one could connect ATX cable and use the HDMI, LAN and USB ports with a custom IOShield. Overall I am happy with the product and it enables me to use my setup in a 19" 1U case. That's all I wanted and ATX-Watchdog is a convenient addon to solve the PSU problem.

Thank you Christian for your thoughtful and detailed review. I'm happy that the board is working out for you. Most of the time, I do not know what people are using these boards for so feedback is always welcomed. Next time this board comes up for redesign, I will keep in consideration that people may want to have the ports of the CM4IOB be flush with a side of an enclosure.
Needed to replace a 20 year old atx mobo in a MAME cabinet. I didn't want to go through setting up another pc solution, and already had a raspberry pi with a RetroPie image. Using this allowed me to pretty much swap the power connector from the mobo to the board and I was off an running, no need to rewire my power button/coin door and marquee lights/etc.
Had a small software issue, the RetroPie image doesn't have all the dependencies needed for the shutdown/reboot scripts. I messaged Tom, and he got back to me very quickly with a suggested fix (use the instructions in the ReadMe here: https://github.com/tomtibbetts/ATX-Watchdog-for-Pi/tree/main/scripts/Ubuntu%20Install%20Scripts) and that solved the issue immediately. Spectacular customer service.
The product itself works great and the documentation is fine even if it is a bit technical.
On mine a few pins were bent a bit, but that happens when you have international shipping. In addition to that there was a missing nut, which is not a problem but weird. If you have another HAT on top of this one it doesn't even matter.

Hi, Thank you so much for your review. And, for being honest. I really appreciate it.
I apologize for the bent pins and missing nut. I kit all this stuff myself so, I obviously miscounted. I'm glad to hear it's not affecting you. I'm still working on how to protect the pins on the assembled units.
Kind Regards! Tom

Things didn't go well but Tom went above and beyond
Things didn't go well with the ATX SPU cool kit, and initially I thought I had messed up the soldering job. I emailed Tom for some help and he was very helpful, and I sent some photos and he gave some advice on how to diagnose what was up.
Long story, short, but it ended up being an incompatibility with the power supply I was trying to use. My soldering was fine! I think the SF power supply was trying to be too clever and was expecting a motherboard, rather than the Raspberry Pi. Before we realised the issue, Tom sent me a replacement board (I payed for the postage) and unfortunately, due to Corona-19 delays, that package was delays some several months. So Tom, being an amazing guy, sent me another replacement, using a different transport company which got to me before the first one!
I've sent Tom the details of the power supply I was initially using, so he can sort that out with future designs.
Thank you Tom, you went well beyond what was expected to resolve the issue. My offer for a beer, should you ever visit my part of the world stands. :) All the best, Stephen
This product was exactly what I needed, It powers my Pi as well as several other devices I'm using that need their own power. I can put everything into a PC case and use the case fans to cool keep my solid state relays cool.
Along with a great product, Tom has been a great help. This was the first time I've done any major soldering and I didn't do a great job. Tom asked for pics and gave me some advice that got me up and working. He's been a tremendous help as someone new to electronics.
I came across PiRyte Mini ATX PSU for Raspberry Pi when looking for the possibility to install my Raspberry inside rackmount chassiss. I've seen some boards allowing connecting Pi to ATX power supply or using its power on/off buttons to shutdown the device but none of them have the AC power loss feature (If the power goes down while operating, the device boots up automatically when power is back, don't have to press the power switch). I wrote to Tom - the author of PiRyte and he wrote back, he would implement the feature. Two days later - it was done. Now the board has all these brilliant features: - possibility to power Pi from ATX power supply, - physical Power on/off, reboot button support, - 2 modes: AC power loss on or off, - board detects when you shutdown Pi from command line and kills the power after device will safely switch off the os (no data corruption) - board detects when you reboot Pi from command line and does't kill the power then. Raspberry acts now like regular server/desktop machine. If you are looking for any of those feature do not hesitate and buy PIryte Mini ATX PSU. You won't find better product somewhere else.
P.S. I'would like to thank Tom very much for his great job, perfect communication and openness for implementation of new features. I also want to thank him for sending new reprogrammed chips for free after I shared my thoughts on adding command line power/reboot handling feature. Best, Michal
Documention is complete and once assembled the product is straightforward to use. It make it easy to use a Pi as a media player in mini ATX enclosure, a pico-ATX PSU and HDD on a SATA to USB controller.
