Hello,
I have a power supply: Be Quiet Straight power 11 (850W).

I bought a video card: TUF-RTX5070TI-O16G-GAMING


Questions:
1. Will the power be enough, because it recommends 850W?
2. Can I connect via the Be Quiet 12VHPWR PCIE-E Adapter cable (which I also bought original), or is it better to connect via the manufacturer's (Asus was included with the board) adapter 3x8?

3. The VGA (Asus) manufacturer's adapter has more small pins than the power supply. I read that this has no effect, but is it really so?

PC Build:
MB: Z690 AORUS PRO (rev. 1.x)
CPU : i5-14600K
RAM: 32 GB
PSU : 850W (be quiet)
GPU: TUF-RTX5070TI-O16G-GAMING

PS: I don't want the VGA to "burn out" due to too little power or something like that. The internet is full of stories about bad adapters or bad connections...

Of course you can use the new adapter. A 300 W GPU with 600W cable is perfectly reasonable. As far as I'm aware the small pins are just grounded or open and don't have a sefeguard function with the Nvidia adapter.

Hello.
The PSU is a good one, the wattage is ok for that build, the only issue could be the multi-rail design because it requires load balancing.
I don't see any problem with using the Be Quiet! 12VHPWR cable, regarding the sense pins please read the last paragraph from this page:
I looked at the PSU manual and to achieve load balancing using the Be Quiet! cable you insert one connector into PCIe3 and the other into PCIe1, but you probably knew that already.
And everything should be fine. The cable connection to the PSU would be quite solid compared to having a 12V-2x6 socket.
