Which 850W PSU Should I Get for My Mini-ITX RTX 5070 Build?
Asked by

I'm upgrading the power supply in my compact mini-ITX system because the current unit isn't powerful enough for my new Gigabyte GeForce RTX 5070 WINDFORCE OC 12GB. I'm looking for a reliable 850W PSU that will fit an ITX build, preferably from Corsair or Seasonic. The rest of the system includes a Ryzen 7 5800X3D and an ASUS ROG STRIX B550-I Gaming motherboard. Which specific model would you recommend?
Answers
Corsair offers several suitable options in this range, including 750W, 850W, and 1000W compact units. For this build, a quality 850W SFX or SFX-L model—such as the Corsair SF850—would be a sensible choice. Just make sure the form factor matches your case and that the PSU includes the correct GPU power cable.

MellowOrbit42: That makes sense, but I couldn’t figure out which specific Corsair or Seasonic model would be the right one, so I wanted to ask before buying.
