I'm considering a system upgrade in the future, so I need a solid, dependable power solution that matches my setup and can support PCIe 5.0 around 1200 watts.
My hardware includes:
Motherboard: Asus TUF Gaming B550-PRO
CPU: AMD Ryzen 9 5900x
RAM: 2x16 Corsair Vengeance LPX DDR4 32GB 3200MHz CL16 (CMK32GX4M2B3200C16)
SSD: 1 x Samsung SSD 990 Pro with Heatsink 4 Tb
SSD: 2 x Samsung SSD 970 EVO Plus 1 Tb
GPU: Asus ROG Strix RTX 3080 Ti
Power Supply: Be quiet! STRAIGHT POWER 11 850W
Processor cooling: Be quiet! Dark Rock Pro 5
Case: Be quiet! Pure Base 500
Case fan: 3 x Be quiet! SILENT WINGS 4 120mm PWM high-speed
Case fan: 2 x Noctua NF-A14 industrialPPC-3000 PWM 140mm
Case fan: 3 x Be quiet! Pure Wings 2 140mm
I'm looking for several PSU models.

I believe you require 1200w for that specific purpose. But you can also review the link provided to see what's available in your area.

I need a lot of power to manage the spikes from the RTX 30 and 40 graphics cards...
I've noticed my existing 850W PSU can fail suddenly during intense PUBG gameplay in 4K, and I couldn't find any other situation that caused this issue.

The issue lies in the insufficient voltage from the 12v rails for the 11 series, and the GPU is linked to two separate 12v rails on the power supply.

I've been using a 3080Ti with 11700k, similar components, on an Rmx 850w for over two years without any problems. My friend with a comparable setup has the same experience. As mentioned, consider separating the PCIe power cable.
Purchasing a PSU for the future with RTX 5 series in mind is challenging. Should I opt for an ATX 3.0 PSU now or wait for 3.1? I don't think 3.1 is widely adopted yet, but some people say it might be better when new graphics cards come out.
