Hi Adam,
The black ground from the Stammheim board goes to a ground on the Teradak Power Supply but it can go to the Mobo ground as well.
The Rex is getting its 5v through a Curious USB cable connected to the JCat V2 USB card with Paul Hynes providing the 5v in on the JCat card.
My current system below.
Audio PC - Gigabyte H97M-D3H, i7 at 800Mhz, RAM at 800Mhz & PPA OCXO Mobo, Teradak ATX Linear for 20 pin ATX on Mobo, Paul Hynes SR7EHD 12v, 5v & 5v supply on Mobo, Stammheim 12x LT3045's for 1.3v to RAM direct supply, JCat V2 USB Card, WTFPlay Linux Audiophile Player control by MELE F10, Startech LEX on JKenny ISO/Regen and REX with 4x SLC USB sticks on 12v Paul Hynes, PPA Red USB Cable, Lampizator Big7, Nige design Lifepo4 powered amp, Raidho C1s.
