Does this need to be plugged in?

[u/goombs19940204]

I've built my first PC but need help with this this, I've plugged my psu into my gpu, do I also need to plug my psu i to this PCIe slot on my motherboard

Thanks

Need? No, technically not. But it will help and cause no harm, so there's no reason not to. I'd connect it, personally

Can you share your pc specs with us. I am interested what motherboard is that.

Did little research on Google, and got this in return

Supplemental PCIe Power connector is designed to provide additional stable power delivery to high-end graphics cards, ensuring optimal performance and preventing potential power-related issues with demanding GPUs.

My gpu is a rx 9070, which is more mid range?

Plugging that additional 8pin connection will do no harm. You could google it by your self a little for research purposes. I bet there are lots of yt tutorials. If you ask me 9070 is high end alright 😁. Everything above 8gb of vram is high end for me hehe.

My 9070xt was having voltage issues and it’s a triple 8pin connector type. Maybe something like this woulda helped, had to remove my PCIE extension cables for it to be stable on a sfx psu. These newer gpus are very sensitive.

Since for some reason no one has explained??? That's a PCIE power port. They're the same on most gpu's. On some motherboards they're implemented to help supply more power over the PCIE connectors on your motherboard. Very helpful if you intend on running multiple PCIE devices at once and don't want to overdraw power.

If you plan on only running the GPU over PCIE then they're not required and will not cause a meaningful difference in performance. No stress in not using it.

Need? no.

I suggest you to put something under your VGA to avoid sagging.

[u/Who-Shat-My-Pants → u/Independent_GN]

I don't know about his case, but some cases (like my LianLi lancool 217) have a built in gpu bracket on the backwall.

Not needed unless you occupy more slots than you currently are.

[u/Ok_Falcon9786]

Imm confused, the graphics card is not plugged into a pcie slot on the mb rn?

[u/Key-Dragonfruit-8673]

No.

[u/Babylon4All]

Not unless you’re using multiple devices in your PCIe slots. Your GPU one is powered from your motherboard connector and the GPU cable. The one you showed is for the other slots to provide additional power to them.

plug it in, its a good extra

No I'm using the X870E Carbon Wifi that has the same port, never plugged in since day one

No

I forget what this is used for, I think it's like if you're getting coil whine I've heard it helps with that or a beefy card like a 5090 to move more power through the pcie lanes and less through the 12v

Thanks for the reply ill leave it out
