[SOLVED] powering rtx 3070ti and rtx 3080ti and its risers with corsair rm850x

[ueharajohji]

I bought this psu to power my two gpu (3070ti and 3080ti) and its risers. But the problem is rm850x only have 5 pcie slots.
4 slots are already given to 3070ti and 3080ti and the last slot will be powering one riser. I was told by other members here to buy corsair additional cables
but in my country the cables set is more expensive than the brand new psu itself (It doesn't make sense). So I am here to ask if I can split the pcie cable for the last pcie slot
to power my two riser w/o burning my house down. The splitter I am planning to buy is this splitter

ps. I am so learning server psu so I can end this nightmare with corsair power supplies :<

You have bought an 850w power supply to run two Ampere GPUs and you want to use a splitter?

Even if just mining, I'd maybe want something a little more powerful.

I just returned my psu 850 watt corsair. Now I am going with 1000 watt with 6pcie slot so I can end this nightmare lol.

Slot?

this time I made sure it has 6 pcie slots to power my two gpus and two risers.
