PC build question :)

I am on PC PART PICKER and I have saw an incompatibility and I am not sure exactly what it means. The error is:

Warning: The video card PCIe 16-pin power connector adapter is being supplied by three 6+2-pin power connectors. Please ensure that the three 6+2-pin power connectors are not daisy-chained and do not share the same power cable.

How do I know if the power connectors are daisy chained and if they share the same power cable?

My current list is below:
Video Card: Zotac GeForce RTX 3090 Ti 24 GB AMP Extreme Core Holo Video Card (£1986.48 @ **********)
Power Supply: Corsair RMx (2021) 1000 W 80+ Gold Certified Fully Modular ATX Power Supply (£149.99 @ **********)

Thanks for any help/advice

The warning is saying that you should have a psu which has 3 pcie cables and each cable should be plugged into just one power connector on the gpu. Daisy chaining is when you take one pcie cable and plug it into 2 of the power connectors on the gpu rather than just the one. https://youtu.be/GvItPB8z9mg?t=212 https://youtu.be/UL7KIVI_hJg
Hope that helps

If they share the same power cable then you have two connectors, so they're saying make sure you plug each one (on the graphics card) into a separate cable.

You get 3 cables with that PSU, I think.

Example of a daisy chain.

2 connectors for one cable. Dangerous if you put a huge amount of load on one cable with a GPU that can spike by 350 watts and the environmental temperature is high (30+ C).

This is an excellent psu and amongst the best you can buy. It will come with all the cables you need to power the 3090ti.

If you look at the picture of the connectors you can clearly see 6 x 8 pin cable connections that you can use for pcie cables to the gpu.

I would imagine that part picker puts that warning up evertime just to cover their legal backsides.
