I'm putting together a PC with the following components: an AMD Ryzen 7 9700X CPU, Asus GAMING B850-PLUS WIFI motherboard, 32GB Corsair RAM running at 5600MHz, a 120mm RGB case fan, a Corsair HydroTitan RX360 liquid cooler, a Gigabyte GeForce RTX 5070 Ti Windforce GPU, and a 2TB Samsung SSD 990 PRO NVMe M.2. I've been advised to use an 850W power supply for safety and future upgrades. However, I already own a Corsair 750W power supply from my previous build. Can I use the 750W to save some money, or should I stick with the recommendation for an 850W?

If your current PSU is reliable, using the 750W is perfectly acceptable for your setup. Generally, anything between 700W and 900W is fine for your components, so you’re in a good spot with what you have!
You can definitely use the 750W power supply, as your estimated requirement is around 700W. Just keep an eye on your system's power consumption, and you'll be fine for now! If you plan to upgrade down the line, you can always get a bigger PSU then.
Sounds good! I just wanted to make sure I'm not cutting it too close.
The 750W should work fine given your specs, but if you ever intend to upgrade to a significantly more powerful GPU or add more components, consider investing in the 850W now. It's usually a good idea to have some extra headroom.
Thanks for the advice! I guess I can always upgrade later if needed.
Great! That helps me decide not to spend extra right now.
