GPU/PSU help needed asap

[Rogue57Chevy]

So I have daily driven my 4090 for some time now but I would like to drive extra monitors from a 3060 12GB I have, problem is, I don’t have any spare 8 pin cables apart from the ones coming out of the connectors going to the GPU as pictured below, do I need a new cable or can I run the 3060 daisy chained from one of the connections going to the main GPU

What's your PSU ? With a good one you can disconnect one cable from the 4090 and use both ends of one pigtailed 8pin instead

Also depends on the max power usage of the 4090, if below 500W you'd be fine

DON'T EVER plug both connectors of one cable into both GPU, as the cable current regulation can't separate the loads !!

I have a 1050W PSU, power draw of the CPU is 253W, 4090 is 450W (afaik) and the 3060 is 175ish

But which model ? 1050W is a bit short for 975W consumption without peripherals (add 100ish..); a good one will work (but may be noisy and get hot), a bad one will fail

I believe what you are saying is for the 4090 to use 2 cables from the PSU, one as it currently sits and the other connected at the middle to one 8 pin and at the end to the other 8 pin which will free up the 3rd 8 pin from the psu for the 3060?

Thermaltake Toughpower PF1 ARGB 1050W, all of my peripherals apart from a headset are ran into a usb hub with it's own power supply

Exactly, 2 cables to the 4090, one connected with both GPU side 8pin connectors, the other with only 1 8pin, and the last cable to the 3060 (one 8pin only)

 

4090 will safely get up to 500W power (2x200 par cable +75 from Pice slot), even if their rating is 150W they can go higher and won't melt - not like the cursed 12VHPWR connector !

Isn't the 12VHPWR on the 4090's? I have a 12 pin going into mine

Still drives and RAM and lights etc run on PSU power, my rig needs 160W when my CPU+RAM need less than 100...

PSU should be safe but it'll be pushed at its limits with 1000+W... Risk is shutdown on GPU power transient surge (+100W at least)

12pins, that's 12VHPWR And you have a 4090 !

So, am I good to go with the cable setup or not? Keeping in mind that the 3060 won't be running anything intensive. What you mentioned about my gpu power connector has me concerned

Yeah there's all of a fuss about that melting connectors lately, check yours is fully plugged, not angled, light a candle, sacrifice a goat etc

Well you can try your setup and see if the PSU shutdowns or not, I don't think it's dangerous as the PSU seems safe (tier A)
