The ASRock PG-1600G is a 1600 W ATX power supply, not a motherboard. It is on the platforms list because people pair it with CMP builds and because its modular connector pinout differs from cables made for other PSU brands. For power in general see Cooling and power.
Modular connector pinout
Warning Meter the PSU side before plugging in any cable made for another PSU brand. Matching housings and keying do not mean a matching pinout, and a cable that puts +12 V where ground belongs will likely kill a card.
GlobalApathy checked his PG-1600G with a multimeter and photos: the CPU/PCIe ports on the PSU panel use standard EPS 4+4 style housings, and on the panel the side opposite the latch clip is all +12 V and the clip side is all ground. Source: @globalapathy, 2026-10-19

GlobalApathy uses adapters with this PSU only because its 4+4 EPS cables have a double-wide clip that does not fit the card. Source: @globalapathy, 2026-10-19 See Cooling and power for EPS cables.
