Hello and thanks for viewing my thread so as the titles says I bought an RTX 3090 FTW3 Ultra but.... The problem consists like this:
 
My PSU brand is Asus rog thor 850w Platinum, which is enough to run the card. The thing that I am most afraid is the PCIE cables which I heard they are quite a bit of a go and miss
 
What I mean by this is that I don't want to use a daisy chain pcie? ( first time I heard that ) or other pcie cables from other PSU's because I heard this is a very bad mistake
 
The psu came with 6 pin and 6+2 pin
 
I am not that familiar with the PSU and how the GPU voltage are working because I paid a lot for the gpu and do not wish to wake up with a Burnt gpu and a PSU
 
Can anybody please recommend me the cables that you guys are using? I am not overclocking anything and don't want to do that in the near future
 
My pc specs are:
i7 10700 non K
32 gb of Ram corsair vengeance
MSI Mobo 490z gaming
Psu its  there
GPU at the moment is 1080 ti which is of course EVGA! 
 
Thanks again and have a good day!
 
 

I did specify that my PSU is ROG thor 850w.
 
my question what brand of 3x8 pin pcie cables should I use in order to prevent unforeseen consequences
 
Thanks!

My question is again like this because it seems that people don't understand my question

Looking up the power supply you mentioned in your first post, the ROG-THOR-850P comes with three 6 + 2 PCIE cables. You would use those three cables to hook up the graphics card.

Nope it only came with 6 pin and 6+2 which would be quite odd this is what is powering my 1080 ti at the moment

 If that is the only cable you have I would definitely suggest reaching out to the manufacturer of the Power Supply as they would most likely have replacement cables to send/sell that would be compatible with your PSU.

You would have to contact the PSU manufacturer and see if they will send you or let you buy a third pcie cable. Honestly, I would get a Corsair RM1000x or a really nice Titanium or even a Platinum 1000w psu at a minimum. 

Is this what you have ?  ROG-THOR-850P
 
if not, what is the part number on your PSU ?

It's interesting...the specifications say it comes with 3 6+2-pin cables, but in the text on the first page it says it only comes with 2 lol

Thanks!

Always better to use 3 independent cables if the PSU permits it. 850 is the recommended spec but for efficiency I always go 100w above the recommendation by a manufacturer.  

Can you recommend me which cables?

it has UP  to (3) dedicated VGA (PCIe for GPU) power sockets ..... two for CPU

The ones ASUS recommends after you contact ASUS.

Otherwise, you can try aftermarket ones like cablemods.

IF you could find the technical spec sheet of the Pin out of the and it matched an EVGA PSU you could get away with ordering the EVGA cables but without that , you are doing the right thing by looking for the correct cables, I would look to see if Asus has/sells extra VGA cables, I would have thought that 3 would have came with the unit.  8 pin on one end and 6+2 on the card end is normal , having an extra 6+2 extra tag is normal , you just don't use that part, I am surprised you do not have at least 3 .
 EDIT: looking at Asus web site the package said it includes 3x cables
Power Cord x 1 Motherboard Power Cable x 1 (610mm) CPU Cable 1000mm x 2 (1000mm) PCI-E Cable x 3 (675mm) SATA Cable x 2 (810mm/860mm) Peripheral x 2 (450mm) Join the ROG badge x 2 ROG logo magnet x 1 ROG label x 3 *MB/ CPU/ PCI-E cables come with embedded capacitors in the middle.
