Do I need to buy a new cable for my MSI 4070 Ti GPU?

I'm currently upgrading my GPU from a 3070 Ti MSI Gaming X Trio to an MSI 4070 Ti SUPRIM X and I have a quick question about the power cables. My cooler is a Cooler Master V850 SFX Gold PSU, which has four 8-pin PCIe outputs. However, the 4070 Ti requires a single 16-pin power connector and didn't come with the necessary adapter since I bought it used. I found a cable on Amazon that seems to be a potential solution, but I want to make sure I'm making the right choice. Can I use this cable to connect three of my PSU's 8-pin connectors to power the GPU's 16-pin, or should I be looking for an official adapter? I really want to avoid any risk of damaging my setup!

You shouldn't need to purchase anything extra! Your Cooler Master V850 SFX PSU should have a 12VHPWR or 12V-2x6 cable included for that 16-pin connection. It's a common feature nowadays. Check again, you might have it stowed away in the box or with your cables.

If you really canโ€™t find the cable, you can definitely use that Amazon cable by plugging three 8-pin connectors into it. Just double-check the adapterโ€™s specs to ensure it can handle the power draw. Itโ€™s always better to be safe than sorry when it comes to power delivery!

I actually checked and couldnโ€™t find that cable either, so itโ€™s possible you have an older model of the PSU that didnโ€™t come with it. Make sure to look for the exact model; your PSU might only support ATX 2.31 and not the later versions that include those cables.
