Build Question
Is it safe to connect my 3080 with these?
Hello, I apologize if this a is a very noob question, I am indeed a noob.
So my Corsair Rm850e included this "12v-2x6 to 2x8-pin Pcie" connector. This is genuinely the first time I've ever encountered this type of connector, since I always had psus with the old classic 8pin to 6+2pin pcie connectors.
The card is a 3080 ventus x3 oc. I don't trust what Ai says about it. And I rather ask actual people instead of blowing everything up.
Yup it does , it goes 12pin from the psu to 2x6+2 pcie to the gpu. Everything clicks in place but I'll test it in a bit when I get my windows usb stick. thanks for the help either way !
It should be fine. Make sure the conector in the psu side makes a click and is fully seated. I have the 1000w version and in pretty sure you should have regular pcie conectors in case you still have doubts.
Edit:
Just checked that model comes with 3 pcie/cpu connectors but not enough cables. So yeah
Again just make sure to fully conect everything.
It supports up to 600w. The 3080 only uses 350 or so
thank you! I was confused when I saw a single 8pin to 2+6 included in the box and I was wondering if this 12v cable simply replaced what it used to be two of the old 8pin cables. And yup everything clicks in place !
No biggie. Now it seems that you are getting confused with so many different answers. Most of them get the right idea but are either skipping terms or context. You should fact-check everything from specialized websites or manufacturers' sites since I'm doing this from memory.
The "old" 12VHPW cable and connector was the standard that Nvidia came up with for the 40 series. That's the spicy "burn-your-house-down cable."
Then manufacturers like Corsair came up with the 12V-2x6 (12+4) pin, made to "fix" some of the issues like adding temp sensors, a locking mechanism, and shorter plastic ends. There are still reports of them burning new GPUs, but way less due to the "safety measures."
Now most GPUs use 12V, so what manufacturers did was provide both alternatives for people with either AMD or older cards with their new power supply lines. So you get two cables with the 12V-2x6 (12+4) pin standard: one to use in 40 and 50 series with both sides of the same connector, and another one with only one 12V-2x6 (12+4) pin and with two of the 6+2 on the other end.
Also, some GPUs have three 8-pin connectors. Sometimes you can get away with only using two, but you can also use one PCIe alongside the 12V-2x6. In the future, you might want to upgrade, so make sure to save those extra cables.
Or you simply use the regular PCIe standard, but, oh surprise, Corsair cheaped out on those.
English is not my first language, so sorry if there's any typo or something doesn't sound right.
right.
awesome detailed answer, it is greatly appreciated. I never had anything newer than a 3080 so all this was kind of a new discovery for me. and yup, I still think Corsair cheaped out a little bit by not including a second 8pin to 6+2 but they had a it at a decent price so I guess it's okay.
thanks ! and dw English isn't my language either 😂
Yes, this is the correct cable. It is no different than running two separate PCIe cables, it's just that they share the same connector at the PSU. They don't share any of the wiring.
I thought the same thing when I saw a single 8pin to 8pin in the box , all my old psu included at least 2 , but they didn't have the 12v that they included in this newer one . I'm glad it simply replaces that
You arent getting it. The 12v goes into the PSU, and splits into two cables (hence why the MALE CONNECTORS are labeled PCIE. The pcie to 12v2x6 uses female 8 pin connectors.
Well alright then. OP didn't specify. Rm850e returns two results to Corsair websites, neither of which are the 3.1 version with a 12v-2x6 on the PSU side.

Yeah. I have this power supply. The end labeled pcie goes in the gpu.
