Help needed and Hello everyone....
First the specs : Dan A4 H20, Gigabyte 9070xt, Gigabyte B850itx, 9700x, Bequiet 240 a.i.o, 32gb 6000cl30, 2tb ssd and psu thermaltake Toughpower 850w platin.

Here is my problem. My GPU needs 3x PCIe 8pin but my psu only got 2x8pin...but got a 12VHPWR. Can i use an adapter (12VHPWR to 3x 8pin) or ( 12vhpwr to single 8pin + 2x8pin to 8pin) to fix this problem???
Or should i switch my PSU instead?
Is there an adapter 12VHPWR male to 3x 8pin male???
Thank you and happy downsizing!

You can use 2x8-pin connectors by making an adapter for 3x8. The rtx3090 has a 2x8 pin in stock and can consume 400 watts. I used it with a consumption of 600+ watts, but I don't recommend it to anyone.
And of course you can have 12vhpwr to 3x8pin.
