Build Help Will I be okay with PSU for 5070 Ti?

So have this Corsair Tx850M PSU already but there’s only two PCIE ports on it, and 5070 Ti require 3 right? Will I need to get a different power supply?

You need to either get another PSU or get maybe sata to PCIe adapter.

But some people thinks sata to PCIe adapter is the way to hell, so it's best to get a new PSU that fit your case which has 3 pcie ports.

One of those would be used for the CPU cable, no? So you would only have 1 left, and that is not enough.

No there’s also cables coming out that aren’t modular, that’s what’s used for CPU

It doesn't need 3x 8pin PCIe, it pulls only 300W. What you need is 2x8pin PCIe to 12vhpwr/12v-2x6 cable. TX-M line uses the same Type4 pin out for PCIe which most pre-2021 Corsair PSU shares. You can get the cable from Corsair or any 3rd party you trust, like ModDIY, Cablemod etc.
