Hey everyone, I'm looking to go with the Corsair RM850e PSU, which is ATX 3.0. I've heard that ATX 3.1 and 3.0 models have the same connectors, just with some differences in the sensor pins. My main concern is whether the 3.0 PSU is safe for my RTX 5070. I'm planning to use the 12-pin cable directly from the PSU without any adapters. Can I trust this setup to avoid risks like melting components? I've read that the 5070 shouldn't draw enough power to cause issues, but I'd like to confirm. Additionally, for my AM4 CPU, I'm considering the Ryzen 7 5700X3D for better gaming performance. However, the Ryzen 7 5700X is cheaper and could save me on cooler costs, making both options similar in price. Which one would you recommend for gaming?

The RM850e is a solid choice! For the power supply, you're right, there's very little risk involved as long as you're using the cable correctly. Your setup should handle 1440p gaming just fine, especially with the RTX 5070 being comparable to the 4070 Super. Regarding the CPUs, since you mentioned wanting good gaming performance, the 5700X3D would give you that little extra edge in frame rates, especially in the demanding titles. But if money's tight, the regular 5700X is still a very capable CPU.
It sounds like you're building a solid rig! The Corsair RM850e should be more than enough for your RTX 5070, especially since you're using the direct 12-pin cable. As for the melting concerns, there shouldn't be any risk. The 5070 isn't a power hog, so you're good there. Now about your CPU choices—while the Ryzen 7 5700X is definitely a more budget-friendly option, if you're prioritizing gaming performance, the 5700X3D is likely the way to go. It's known for better low-end performance which can make a noticeable difference in gaming. Just keep in mind the budget and future upgrade plans!
Totally agree with you! The 5700X is a great chip, but if you're after those extra frames, I'd say the 5700X3D is worth the investment for gaming.
Exactly! If budget permits, go for the 5700X3D. As games get more demanding, you'll be glad you did!
