Hello, thank you for this nice information base.
Two weeks ago I owned a pre-owned CoinCraft with 5 modules and an ANTEC 1000W PSU.
I decided to upgrade the PSU to an LEPA 1600W.
After connecting it and switching it on, the PSU knocked two times. I unpluged all connections except the mainboard connector and switched it on again...
I saw smoke and realized, that the connectoin on the PBC-Board from PIN 24 to C18 to C16 burned!
Since that its not possible to start the unit, neither with the original ANTEC PSU.

.
Now I will try to fix the PBC board, but I don't know the function of the capacitor and the resistor.
So please help me with this questions:
Could this be an issue with the PSU-ON-Pin? Is there a difference between the ANTEC and the LEAP PSU?
Is it possible to buy a new PBC from anywhere if I can't fix it?
What did I made wrong?

Many thanks for your help!

The LEPA 1600 is a multi-rail PSU with six 12V rails (4 x 30A and 2 x 20A). However only four 12V 30A rails are accessible as PCI-e. Plus you need to pick the correct connectors to make sure you don't plug 2 PCI-e cables into the same rail. The Desk needs five PCI-e cables, so for the fifth cable you need to make a custom PCI-e cable connected to one of the remaining 12V rails, which by the way are only 20A rails.

Chances are you did something wrong while doing this.
