I'm searching for a suitable SFX, SFX-L, or ATX power supply (less than 140mm) to fit into my NCASE M3 Round for a powerful AMD build. My current setup includes an AMD Ryzen 9 9950X3D processor, Arctic Cooling Liquid Freezer III 280 AIO, Asus ROG STRIX X870-I GAMING WIFI motherboard, 96GB Corsair Vengeance DDR5-6000 RAM, a 4TB Samsung 9100 Pro SSD, and an Asus ROG Astral GeForce RTX 5090 OC Edition graphics card. Any recommendations for a power supply that can handle this build effectively? If you see any issues with my specs, I'd love to hear your thoughts!

You don’t have a lot of high-power SFX PSUs to choose from, but the Corsair SF1000 is a solid pick for your setup. It should handle the load well enough without issues.
If you're willing to spend a bit more, the Corsair SF1000 Platinum ATX3.1 is a great choice for SFX. However, to be safe at maximum load, you might want to consider going with an SFX-L like the ASUS ROG Loki 1200T, although it’s quite pricey. For a smaller ATX option, check out the Montech Century II 1200W or FSP Group Hydro PTM X Pro Gen5. I found some helpful links to better power supply options too!
Is the SF1000 really enough power to run both the 5090 and 9950X3D at full load?
