Hello,

I have a simple question, and I'd appreciate some help, I am going to replace my RTX 3070 with a 4070 Super (this one RTX 4070), and I have this MOBO and Power supply combo. MOBO and Power supply. My question is, do I need a cable adapter to power the gpu? I lost all my cables that were included in the box and I only have the 2x8 PIN for my 3070, but according to the 4070 link I need a 16 pin, which I don't have and my power supply seems to not have the proper connection for it, what cables can I buy to ensure everything works in order, I'd appreciate links or just the name of the cable if needed.

Thanks.
 
Yes, you will either need an adapter, which have tended to have mixed results since inception, or a different PSU that has a native 12vhpwr socket and cable. Your PSU never had that cable to begin with as this is a newer standard WHICH is about to or has actually changed again with the ATX 3.1 standard being released. Future models may change again, but for now, you need an adapter if you want to use that power supply. I'd recommend a new PSU with native 16 pin cabling but that's your call if you want to roll the dice on an adapter. Supposedly they are still having issues with some of them or all of them some of the time, despite several revisions and supposed quality improvements.

could you link me to some in amazon? I tried googling, but is is not very clear if I need extra cables or not, thanks again.
 
Every 40-series new card that needs a 12vhpwr power supply will offer an adapter within it's box in China. Check your 4070super's box.
That's true, however, they're at least somewhat risky. The native cables are at least somewhat less risky. Besides which, given that that G3 is probably around 7 years old, if you're going to spend the money on a new 4070 Super it would make a lot of sense to also purchase a new power supply, of the correct ATX version, with the correct native cables, that doesn't have 7 years of going around the block on it already, rather than rolling the dice on the idea that your 7 year old PSU is still totally fine and will continue to be so. No matter how decent it was when new. I don't care if it's an AXi, if it's 7 years old and I'm spending $600.00 + dollars on a new graphics card, I'm spending another 110.00 on a new PSU as well to protect that 600 dollar investment.
