[SOLVED] PSU pcie cable solution

[cameul]

my PSU come with 2 PCIE cable which each of them come with spilt dual 6+2pins
my 3080 which need 3x 6+2pin for power up.
it end up i have use 3 of the 6+2pin and left 1 6+2pin from other spilt.
my question is. can i use the last 6+2pins from the spilt for power up other component ?

What make/model PSU?
For RTX 3080 - 750W PSU is recommended.

What exactly do you intend to power with remaining 6+2pin connector?

i have a CoolerMaster V1000 which rate at 1000W
the remaining 6+2pin from the spilt is for the another card whi ch is 3060ti.
will it work?
i was thinking to place the 3060ti on the motherboard PCIE slot and connect it with the remaining 6+2pin

1000W would be barely enough to power both those cards simultaneously.
But if you avoid any overclocking, this should work.

Why do you need 2 cards? Cryptoming or something?

yes just started to try mining.
my main concern is it safe to use the another split 6+2pin connect to another gpu instead connect to same gpu.

Should be safe, yes
(as long as you avoid any cpu/gpu overclocking).

Mining will put a pretty big stress on the video cards, which means decent power draw. Look up the tested high power draw off the cards, do some math and see how close that gets your system to your PSU max with a 20% or so headroom, so for a 1000W PSU, you want to keep it under 800 watt usage.

thanks for answering my question.
i just read some post about burning rxt3090
worry it will have the same incident because of my PSU cabling to GPU

i believe it is sufficient of watt for power up when all the cards are mining.
the only concern for me is can i use the split 6+2pins which the other spilt have connected to other GPU.
it mean 1 PCIE cable with dual spilt connect to 2 different GPU.

It should provide the power needed, no different than two of them going to one card. The best setup is to have power going form separate cables, but the split single cable still works.
