It is really interesting when un-informed people give there best opinion on how something might work! DLL Industries has sold thousands of these adapters and NOT ONE has failed or has been returned due to failures of any kind! Funny how you make a product and everybody becomes an expert in something they know nothing about.
We have consulted with several major power supply company's (there are over 80 major producers of PSU,s) Talking with them "the engineers" they did not have any issues with the adapter, and as long as you load it with something it just works! I think they know that some of us out here are going to mod a PC and try to hot wire a second PSU. Come on guys, it is a relay that gets powered by 12vdc (4-pin) and energizes a relay that short the power on pins on the ATX. This is real rocket science. No big secrets here. It is just better than cutting some wires and soldering it all together.
And as for the link to the failed adapters video, the guy had a mis-wire, and we asked him to retract the video, instead he made another one that show it all working good. His excuse was that he prayed a lot and got it work. Hmmmm. The Add2Psu is sold at: XOXide.com, FrozenCPU.com, Amazon.com, MicroCenter.com, several university computer labs and countless bit coin miners who order 30-60 units at one time just to name a few and over 30 countries world wide.......
So now I wonder what everyone will say when we introduce the new Add2Psu-D adapter? Yes it does the same thing as the first adapter but this one lets you set an OFF delay from 5 seconds to 7-9 minutes (depending on the voltages of your PSU). If you have your fans on the second PSU, this will allow the fans to stay on while the first PSU is off.
You try to make something for people to make their life a little easier and their is always someone wanting put you down so they can look taller. We also manufacture 15 foot poles! (better than the 10 foot version)
