Your setup looks mixed but generally feasible. You have a PSU with HX850 Platinum, an MSI Pro Z690-A, and a VGA 3080 Ti. The CPU has two 4+4 pins—consider using only the first set for power if you plan to run one CPU. The second 4+4 pin is likely for additional power or future upgrades. Connecting the second CPU in 12V would work, but ensure it matches your motherboard’s requirements. Check your PSU and motherboard manual for pin configurations and power delivery guidelines.

Now optimized for CPUs, motherboards, and memory. Just one 4+4 unit required; the second is reserved for heavy overclocking.

The second group of 8-pin connections is intended for boosting performance. It’s probably not necessary. The voltage should be 12 volts, but handle with care—this setup is distinct and could damage components if misused.

No. This is a 12900k were talking about, the powerhog that it is. In a blender load, the 12900k pulls nearly 250w, which is more than the 235w that a single 8 pin can provide. That means you could conciveably have a power spike that will trip the ocp in a gaming workload

I didn't realize just how much power the 12900k could handle.

You should consider replacing your power supply unit.

No? The hx850 is suitable for a 5-8 pin GPU and 8 pin EPS cables. It includes the necessary cables, covering 3 PCIe and 2 8 pin EPS ports. Just connect both EPS cables.

Sources don't agree with each other but I've seen 300W ratings for 8-pin. I've been running my OCd 5960X that draws about 290W at full load on a single 8-pin for 7 years. Also OCP doesn't care about the number of connectors, only rail separation if any.

Yes, you can label this as a solution. I’ve noted the various topics from PSU outputs and plan to benchmark one at a time before expanding the setup.
