I'm working on a new PC build and could use some assistance. Here's what I have so far: a Ryzen 5 7800X3D for the CPU, a Radeon AMD 9070 XT for the GPU, and a Gigabyte B850 Gaming X WiFi 6E motherboard. My cooling solution is the Arctic Liquid Freezer 360 Pro, and I'm running 32GB of DDR5 RAM along with a Samsung 990 Pro 2TB SSD. Currently, I'm looking for a power supply unit (preferably 1000W). Any suggestions? Also, I'd appreciate feedback on my other components—are they good choices, or should I consider changing something? Lastly, I'm uncertain about which brand of the 9070 XT to get. Are there significant differences among them?

I have an 850W Be Quiet Platinum PSU with similar components, and it works perfectly. For the 9070 XT, I'd recommend going for brands like Sapphire, XFX, or PowerColor—they are well-regarded.
You might want to check out this build link I found: [pcpartpicker.com/list/62MsYX](https://pcpartpicker.com/list/62MsYX). With your setup, you actually don't need a 1000W PSU; an 850W will do just fine.
But what if I want a quiet PSU and plan on slightly overclocking? Would 850W still be enough?
I use an MSI 1000W fully modular PSU, and I’ve been really happy with it. Just make sure you choose a reliable brand and don’t skimp on the PSU—it’s crucial.
