Is my 750W PSU enough for an RTX 5070?

Hey, I just got myself an Asus RTX 5070 Dual OC and I'm curious if my PSU, the Seasonic B12 BC 750W (80+ Bronze), is adequate to power it. Should I consider upgrading my power supply, or is it safe to stick with what I have? Any recommendations for solid and reasonably priced PSUs would be greatly appreciated! Here's what I'm working with: - Ryzen 7 7700 - Asus Dual RTX 5070 OC - MSI B650M-B motherboard - 1x16GB Kingston Fury DDR5 5600MHz CL36 - 1TB NVMe M.2 SSD - Seasonic B12 BC 750W 80+ Bronze - Kolink Observatory HF Glass ARGB with 6 case fans Thanks in advance for your help!

It's not the worst option, but not the best either. Just make sure you're monitoring your power usage. You should be fine with what you have.

You're good to go! The RTX 5070 has a minimum recommended PSU of 650W, so your 750W should be more than adequate. I'm using a Seasonic Focus Gold 650W with my setup (5700X3D and 5070), and I havenโ€™t faced any issues at all.

Absolutely, 750W is more than enough for that setup! You shouldn't run into any power problems there.
