Question PCIe daisy-chain cable vs PCIe single connector power cable for GPU?

[HWright001]

Hi everyone. I got my RTX 3060 and replaced my previous graphics cards with it. For power, I used one of those PCIe cables that has multiple connectors (daisy chain cable) but I'm NOT using it to daisy chain the graphics cards - I couldn't if I wanted to, the card only has one 8-pin connection slot. The cable only has one connection on it: the GPU.

My question is, should I have used a single connection PCIe cable or will the daisy-chain PCIe cables function the same as a single connection cable when only using one connection at the "end"? Is there like a "bleed off" of power or something due to the many possible connectors on the same cable? (As you can tell, I'm no electrical engineer. >-<)

I want to make sure my new GPU has the best possible scenario for power, as I am going to use it a lot for heavy gaming, video editing, and such. Does the "type" of PCIe power cable matter in this scenario? I've been using the card for a few days without issue, so I might just be paranoid but want a 2nd opinion. Thanks!

Edit: I'm using The Corsair RM750x PSU for reference.

Using a SINGLE PCIE 8-PIN cable is better if the GPU only requires an 8-PIN power connector. Which power supply/PSU are you using ?

Realistically it doesn't matter, but if your PSU came with both a single connector and a daisy chain you may as well use the single connector. I used my 1660 Ti (single 8 pin) on a daisy chain connector for quite a while because I didn't feel like re-routing a new cable when I did a GPU swap and had zero issues. Quality of PSU matters infinitely more than the cable type.

The Corsair RM750x. I looked through all my cables and it only came with 2 PCIe cables - both daisy chain. (The picture in link says 4 PCIe connectors, but they are kinda being slick and included only 2 daisy-chain cables with 2 connectors each (6+2 pin) = 4 "connectors" total. Kinda strange.)

There is what looks like a single PCIe 8-pin cable, but it was labeled as "CPU" on its connector and not PCIe as the other 2 were so I didn't use it. Plus, the previous GPU I upgraded from only had a 6-pin connector so I had to run the 6+2 cable at the time.

I am not in a hurry to crack open my case and start digging around with the PSU -which is quite cumbersome to deal with due to my case- to switch out cables unless I really need to. Can I just leave things as be?

I have the same power supply and I used the daisy chained cable for my RTX 2070 Super. Nothing bad came out of it. As long as you're using the ones that came with the PSU, there shouldn't be a problem, nor do I see a problem.
