You're looking for advice on managing your GPU power setup. It seems you're using a 9070xt Asus Prime with two cables, each having two ends, and your PSU has four 8-pin connections split between CPU and GPU. The question is whether you should keep this configuration or consider upgrading. Reddit discussions suggest some debate, but the key points are that connectors support 150W, and cables can handle more power. You might be able to run the CPU with just one cable if you buy a PSU with fewer connections, but it's worth checking your PSU specs first.
The PSU works well with daisychain as long as both the power supply and cables are good quality. Your CPU requires just one 8-pin EPS connector, and having two connectors is usually unnecessary except for overclocking purposes. Even my 9800X3D only uses a single EPS slot on the motherboard.
The RX 9070XT draws up to 300-350 watts. The PCI-E slot delivers between 75W and 150W depending on the version. If your motherboard is still functional, it needs just a couple of 6-pin connectors (75W) or one 8-pin connector (75+2W). Some designs include three 8-pins, supporting up to 600W. Pairing two 8-pin cables covers the requirement without needing a high-power PSU. This model isn't compatible with 4090/5090 form factors.
They offer the necessary cable for around €30 including shipping. This allows using three cables while keeping only one for the CPU.
