Power supply:

• based on cheap (bought used) server power supply HP-HSTNS-PL14
• with output voltage raised from 12V to 13.9V (including increasing over voltage protection threshold) based on description by SP4UBW: https://drive.google.com/file/d/170oBM0Qkuk-mvYwnmUb5sL89MSgW5x9Z/view (PL). Skip this if you just want 12V.
• 5 x XT-90 sockets (https://aliexpress.com/item/32832063718.html)
• power on/off switch (https://aliexpress.com/item/33055369698.html) that connects 330Ω resitor between pins 1-4 of psu socket (to turn psu on)
• meter (PCB from https://aliexpress.com/item/1005005161239649.html with 12AWG wires replaced with thicker ones (10mm2 in my case))
• few M3 screws of various types and lengths; short 3mm grew scrubs for locking XT90 connectors are also handy
• 10mm2 wires inside

Note: playing with PSU can be very, very dangerous due to high voltage inside!
