Ultimate PSU
BE QUIET is probably the best PSU brand there is. I own a Dark Power Pro 10 from 2013, which is still working, and I chose the Dark Power 14, at 850 Watt, for my new build. It is intended to power 1 MSI X 870 Tomahawk, 1 AMD 7800X3D, 2 SSD, nvme PCIE 4.0, 5 Pure Wings 3 140 mm PWM, 2 Silent Wings 4 120 mm PWM, and 1 ASUS Prime RTX 5070 Ti OC. For the GPU, I used the "be quiet! 12V-2X6 / 12VHPWR 90°" angled connector available on the website; it is perfectly compatible with the GPU. I haven't enabled 0 RPM mode, and the PSU is ultra-quiet. Nor have I enabled OCK mode. Top-tier "Titanium" certification for a PC that runs non stop. I therefore needed reliability and silence. All the cables are fitted with heat-shrink tubing and are black. They're a little stiff, but can be softened so they're easier to handle. All these parts are installed in a COOLER MASTER Master Case Pro 5 case. It's an investment, but I really don't regret my choice.
