I'm building a new PC with the following components: Corsair mp700 with an air cooler, AMD Ryzen 9950x3d processor, Corsair Vengeance RGB 64GB DDR5-6000 RAM, MSI GeForce RTX 5090 32G Ventus graphics card, MSI MAG X670E Tomahawk WIFI motherboard, a Corsair iCUE LINK QX120 RGB Expansion Kit (120mm, 2-pack), a Corsair iCUE LINK QX120 RGB (3-pack), a Corsair 3500X ARGB case, and a Corsair Nautilus 360 RS ARGB cooler. I'm not sure which power supply will be suitable for my setup and if it will fit the Corsair 3500X case.

I recommend getting a fully modular power supply that has an 80+ Gold efficiency rating. It's also smart to check out a tier list for the best options. For your build, you might need around 1000 to 1200 watts to handle everything without stress.

That sounds great! But how can I verify if the PSU will fit in my case?
