Is the Cougar GEX X2 850 ATX 3.1 suitable for an RTX 4070 Super GPU?
I purchased a Gigabyte RTX 4070 super gaming OC and had the Cooler Master MWE 750 80+ bronze, but it was listed with a C in the tier. I knew it wouldn't be sufficient for the RTX 4070 super, so I looked for a better PSU. I found an ATX 3.0 model and heard about issues with 12V 4W power supplies, so I searched for an ATX 3.1 model with 12V 2x6 new and safer connectors. I discovered the XPG Reactor ll VE 850 and the Cougar GEX X2 850. In reviews, the Cougar is said to be better—does that really hold up?

Both units should handle the task. Are these the only options available? What about Corsair or Seasonic?
The Cougar offers solid performance; an 850W setup works well, and even 650W would suffice. You're all set with this choice. It outperforms the XPG Core Reactor II VE as well.
I looked for a PSU compatible with ATX 3.1 for Gigabyte RTX 4070 super. I found three options: couger gex x2 850 w, MSI MAG A850GL 850 w, and Xpg reactor ll ve 850 w.

That's it.
Are you certain you have the correct PSU? Checking the tiering rules for Tier A in the PSU list shows:
And it confirms that the PSU's specifications are sufficient.

Even though the caps come from Elite and CapXon rather than the top-tier manufacturers, that doesn't imply they're of low quality.
Additionally, the Tier A requirements don't mandate that all caps must be Japanese-made or that the PSU's fan needs to be semi-passive.
Therefore, according to the Tier A guidelines, the XPG Core Reactor II VE qualifies as a Tier A PSU.

It's not bad in itself. Tier B+ improves upon other same tier PSUs, though it doesn't reach the level of Tier A.
One reason it isn't Tier A is that the 12+4 pin PCI-E rating at 450W corresponds to wire gauges of 16AWG to 28AWG, whereas for Tier A the minimum gauge should be at least 18AWG and not thinner (meaning it excludes 20, 22, 24, 26, 28 AWG, etc.).
