Thank you for your response, makes sense!

Thanks guys for the responses, despite the fact that most are in response to the other person. 
I've seen the shared chart with maximum wattages a few times and I know I'm not exceeding them. But here's the question:
Is the load evenly distributed across each cable, or is possible that the GPU may overdraw from one cable and not the other?
So if my 3080s are each hooked up with two 6+2s, and one part of that cable powers the riser, is it possible that the card will draw most of what it needs from just one cable, thus potentially overdrawing the cable?

you wont like this answer but the safest way to fix this is as follows.
cable a to jack a in gpu a and an extension to second plug on that cable a plug that into second gpu
cable b. copy that above
cable c copy that above
cable d one to a riser and use an extension to second riser.
this setup insures indentical shared load on all four cable. it also requires four pcie to pcie extensions.
every cable is used on both gpus loads are equal.
do,you need to do this maybe maybe not.
more likely to have runaway tdp on windows then on linux.
i do a few windows and my 125 setting on a single 3060ti does runaway to 195 or 212 once or twice a month.
never happens on my linux based smos.

Not taking side either but I've been mining crypto since 2016 before even knowing that bitcointalk forum existed, you don't have to judge him because he might be right, some have been into crypto for long and they are just joining this forum, let's all respect ourselves pls
How/where did you learn what sw to use, what hw to use etc to get started?

Here you go...all connectors and limits for ATX psu.
Respect wattage limits and remember no single connector or combination of connectors on the same chain should exceed the wattage ratings listed. Stay inside those ranges and no issue.

Harsh....
Not taking sides here but just because he started in 2019 on Bitcointalk doesn't mean he hasn't been mining prior to him signing up!

The 6+2 can be split to dual 6 pin and power 2 risers. There's no problem if you keep within
the original cable limits. Your cables are dual 8 pin (2 x (6+2) ). 8 pin is equivalent to 2 x 6 pin.
So one cable can power 2 x 8 pin, or 4 x 6 pin, or 1x 8 pin + 2x 6 pin.

Hi everyone,
I've followed all the advice on how to safely set up PSUs and power your GPUs to ensure there's no fire hazard. However, I can't find definitive answers on a pretty simple question in ANY of the articles or videos.
I am running RTX 3080s, and they require THREE 8pin connectors from the PSU. The PSU supplied cables have 8-pin to dual 6+2 pin Y cable. As a result, two cables are needed to power a single GPU, and we have FOUR 6+2 pin cables from them. However, we only need 3 to power the GPU, so can the remaining 6+2 cable that dangles off to the side be used via a 6-pin female to 6+2 male extension to power a riser?
Thank you so much for clearing this up.
