2 connectors for 4+4 CPU interface
Hello, Your power supply only supports 3 PCI-E or 4+4 CPU slots, with two already occupied by your GPU that requires 3 8-pin connectors. That leaves you with one of the remaining slots for your CPU. Using a 4+4 connector will work if you have one available; otherwise, you’ll need both. Your motherboard is the ASUS ROG STRIX Z690-A and CPU is i9-12900K. If you use one 4+4 connector, everything should function; otherwise, purchasing a new power supply might be necessary.
Avoid using a PCI-E power connector for your CPU. It can cause harm. Use only cables meant for their purpose. An 8-pin connector works well unless you're overclocking.
As noted, avoid inserting a PCI-E 8-pin (6+2) connector into the 8-pin EPS socket. Doing so could damage the CPU and/or motherboard. One 8-pin EPS connector can deliver up to 384W to the CPU, which is more than enough for an i9-12900K, even with overclocking. You don't require more than 700W unless you're attempting extreme overclocks like Liquid Nitrogen.
You're questioning if all three highlighted ports could support either a 6+2 PCIe slot or a 4+4 CPU slot. Since you're using the bottom-left ports for your GPU (3-8 pin connectors) and want to use the top-left port for your motherboard, you're left with limited choices—only one of those slots remains available.
Of course. However, the opposite end of the cable isn't the same. They differ in physical form.
I understand you're clear about the situation. Let's keep it straightforward.
