My Aorus x570 xtreme motherboard has a 6-pin PSU connector for helping to power multiple PCI slots in a 2+ GPU setup. Both of my GPUs take double 8-pin PCIe PSU connectors (each of which uses an independent cable), so I'm curious whether this even makes a difference. Because all four of my PCIe PSU outputs are consumed by direct connections to GPUs, I had to use A sata to 6-pin ATX converter which seems to be working well.

Until more of my custom loop equipment arrives, both GPUs and up being thermally constrained, so it'll be interesting to see whether there's more overclocking headroom once some more heat can be dissipated.

While I had everything opened up, I hooked up the two thermocouples that came with the motherboard, and now can keep an eye on the intake-to-exhaust temperature drop

Only need to receive the D5 pump, fittings and coolant. Then, ready to get this first build started!

Custom loop veterans: if you could send advice back in time to your past self, to help ensure building your first loop went well, what would you say?
