Question about be quiet! Dark Power 13

Hello everyone :) I would like to ask you what kind of power supply you would recommend. I currently have a 1000 watt power supply in my computer. It is gold standard, but maybe about 7 years old. Since I'm not at home at the moment, I can't tell you exactly which one it is. However, it is a Cooler Master power supply. In my PC there is a new ASUS ROG Strix Z690-F Gaming Wifi and an ASUS GeForce TUF RTX 3090 Gaming 24 GB installed. As far as I can see, both also need 2x 8-pin PCI-E connectors, i.e. a total of 4 such connectors. With my old power supply I have enough such connections directly. But does the new be quiet! Dark Power 13 1000 W also have four such connections? Off the top of my head I can only see two. Regardless of my question: Would you recommend a different power supply? And if so: Why? And in general: The reason why I am looking for a new power supply is because I was told that if the old power supply is already as old as in my case, problems can often occur and it is also no longer technologically up-to-date. So far, however, I have not been able to discover any problems. LG Eurydikles
