I have just bought a gigabyte 4070 TI super upgraded from a RX 5700. My power cables do not match the cards will I need to change the cable?

You will want the full 6**+2** PCIe plug, yes.
Unplug that 2 into 1 cable you have. You can just plug those others right into the 4070.
Yes, you need 2 full 8 pin cables. The current 6 pin connect you have is dangerous
Aren’t those cable extensions? Or did you order custom cables?
My first question was how did they use a rx5700 to make a 4070?
Your power supply is not enough. You’ll need to change your power supply.
Get a atx3.o pcie 5 750w or higher rated psu
i think your psu is very old.
You will need to swap the power supply if they do not provide cables for that lay out. It’s not worth trying to make it work.
bro. bro. bro. youre supposed to research all your hardware for compatibility before you buy a component that is several years newer than all your other ones
The extra 2 pins are a “sense” and a “ground” connector. Considering how it’s routed the adapter it’s probably fine.
Also, for reminder, most of 8pin connector have the 2 extra pin connected to a pair of the 6 pins, so the 6 cables handle 150w just fine.
What PSU do you have?
Regardless, it shouldn’t even work. There’s an IC on the 12VHPWR end that would prevent it from booting before a disaster even happens.
(What’s with the downvotes? This sub has a problem with [facts](https://www.igorslab.de/en/this-is-how-nvidias-4-fold-adapter-for-12vhpwr-connection-of-geforce-rtx-4090-works-with-workaround/), doesn’t it?
If you upgrade from a 5700 to a 4070 to then get a new PSU to accommodate it and give it the extra power it needs. 700w and above just cause I’m the paranoid type but YMMV, modular and please two 8-pin and not the possible explosive hazard you got in the picture
no way i would plug that into a new video card! just asking for a fire
Is your PSU sufficient? That’s a big upgrade
Seems like those are extenstions. Use the wire directly from the PSU and you should be fine if you got 2 8 pins
I may be wrong, but those just look like cable extensions. The actual PSU should have at least two full 6+2 pin pcie cables. Might just have to get different cable extensions.
Alternatively if your PSU supports it, you can get a dedicated 12VHPWR cable from your PSU brand (that matches with your PSU model) so you don’t have to deal with the adapter and get a cleaner look overall.
I got one for my Corsair RM750 psu and it’s sooo much better than the split adapter from Nvidia.
What cpu are you using? I have the same gpu, but I wanna upgrade from the 12400f.
Follow up question:
My brother just upgraded to a 4070 ti super. We had to get a new power supply since the original only had one pcie cable.
The new power supply is modular and has a dedicated 12vhpwr port that came with a cable rated for 450w.
We ended up using the 2 pcie ports and the adapter that came with the card. Should we have used the 12vhpwr port instead? Are there any advantages to do it one way or the other?
