  • It looks like regular PSUs are isolated from the mains ground with a transformer. That means that two PSUs’ DC grounds will not be connected. That will likely cause problems for you, as they’ll have to back flow current in places that do NOT expect back flow current to account for the voltage differences between the two ground potentials. Hence it might damage the GPU which is going be the mediator between these two PSUs - and maybe the mobo if everything goes to shit.

    Now I am not saying this will be safe, but you may avoid that issue by tying the grounds of the two PSUs together. You still have the issue where if, say, PSU1’s 12V voltage plane meets PSU2’s 12V voltage plane and they’re inevitably not the same exact voltage, you’ll have back flowing current again which is bad because again nothing is designed for that situation. Kind of like if you pair lithium batteries in parallel that aren’t matched, the higher voltage one will back charge the other and they’ll explode.














  • It accomplishes the same thing as Proxmox (VMs and LXC containers, which are “lite VMs” for if you wanted a Linux VM), I recently learnt about it too! It is new, but it was backed by Canonical up until the LXD/Incus split so it’s very solid. Split because Canonical tried to control LXD heavily, so they forked and renamed it Incus.

    I just used Incus and it’s very nice, use the profiles to create a profile for “GPU pass through” and “macvlan”, among others you’ll find you want. Then make instances as needed! It was easier for me to use than Proxmox.


  • First try an HDMI dummy plug, in case the thing doesn’t dig no screen (classic intel firmware)

    Then try Debian + Incus, less Proxmox shims to go wrong. Install Incus via the “zabby” repo mentioned on the incus install page. Search for “LXD” if Incus help/guides aren’t enough for you, they’re the same thing (for now). Providing an ISO in Proxmox is really clunky, and incus smooths that out so nicely. And again, less Proxmox shims to go wronk
