[SOLVED] 2 8-pins

[Undeafen]

I just bought the RTX 3070 and I don’t know what to do with these 8 pins… Zotac got the cables in the box, but it’s not even long enough. And where do I put those white pins?

the cables in the box, throw in the trash. you should have two hopefully separate 8 pin cables coming from your PSU. both of them, need to be inserted into the GPU.

if you don't have 2 eight pins, you need a new PSU

Which one is it from these two?

 

[Jacozeelie]

Both 8 pins must be plugged in

the cable on the right should be the 24 pin for the motherboard. The cable on the left has an 8 pin that plugs into the PSU and then has what looks to be 2 6+2 plugs on it.

If you can tell us the make and model of the PSU we could help you out more.

It’s Corsair RM750x

You should have 2 of the cables on the left in your picture, plug them both in and use 1 6+2 plug on each cable and plug them into the GPU

About the cpu power, how am I gonna plug two of these cables if one of the thing in the motherboard is only 4 pin? the motherboard is msi mag z490 tomahawk.

 

[faalin]

for the motherboard you will use both of the 4+4 cables. if you look at the end you can ether attach both 4+4 to make an 8 pin or leave them apart and only use one of the 4 pins, you just leave the other 4 pin part of the plug hang there.

Use two PCIe 8-pin cables from your PSU. In picture above - at upper row, right side.

I can’t plug the cpu cable. do you think I should remove this big ass cooler and just use the stock cooler of i7-10700?

Why you can't plug CPU cable? Which cooler you are using?

From picture it seems like Be Quiet! Dark Rock Pro 4. I have it - not that bad to plug in CPU power cable(s). However you should do that before cooler mounting. Otherwise cable replugging is quite difficult - but possible. Already did that once

Skip stock cooler - it is sad excuse of cooler FTW.

I don’t think my cpu cable fits because it’s 8 pins and the thing on the side will interfere… in the manual of the motherboard there was a 4 pin power cable...

Oh wait, I saw someone with the same problem and someone answered “The +4 pins are for extreme overclocking.”

If your PSU is Corsair RM750x as you stated above, then you must have two CPU power cables with 4+4 pin connectors. At least that is written in your PSU manual. Connect first one with to CPU_PWR1 socket (with both sides together) on motherboard. And one 4-pin half of other cable connector into CPU_PWR2 socket. Are it is too difficult?

Don't bother and connect both cables. You will be happy to be free of random glitches in very power slurping games later.
