Which one should you choose, the Corsair RM850x Shift or the Seasonic Vertex GX 850?
I can afford either, but I’m looking for the more secure option for the long run.
I don’t know which is better.

Hello
BueTera
It’s tough for me to give a direct answer right now. Are you integrating this into an existing setup or planning something new? Could you share the complete specifications of your current rig, including the manufacturer and model of your existing power supply?

If you have a 40 series GPU (or a 3090 Ti) with the 12+4 pin connectors, the SeaSonic Vertex GX850 might be a good choice. But if you don’t possess a GPU with the updated connector, the Corsair RM850x Shift could offer cleaner cable management. I’m unfamiliar with either option.

I’ve been interested in newer PCIe 5.0 / ATX 3.0 power supplies, but none have really caught my eye yet. For now, I lean toward traditional models. The Super Flower Leadex are the ones that fit EVGA G2/G3/P2/T2 power supplies. I own both the EVGA and Super Flower versions. The main distinction is that the Super Flower models don’t have sleeved cabling and may have different fan curves—though I haven’t personally observed this.

The titanium variant linked here is currently discounted to $155 USD.
Additionally, a new 12+4 pin cable compatible with this unit was released recently for $17. There’s one customer review suggesting that NewEgg’s support might send the cable free if you contact them directly. I haven’t verified this.

No matter your budget, you have several choices.

Thank you for your detailed response. It's also challenging to find PSUs these days. There are simply too many choices.

Ensure you are prepared for the side-mounted cable setup of the shift.
