VR Build - i5 9400 good enough? 600w PSU for 3080 Ti?

My HTPC has the following

  • Intel Core i5 9400
  • ASRock Z370M-ITX/ac
  • Corsair Vengeance LPX 16GB (2x8GB) DDR4 3200MHz
  • Noctua NH-U12S w/ Noctua NF-F12 PWM
  • GIGABYTE GeForce RTX 3080 Ti 12GB (On its way)
  • be quiet! Pure Power 11 600W Power Supply
  • Fractal Design Meshify C TG ATX (On its way)

Questions on this. Is the 600w PSU good enough for a 3080 Ti? My desktop which has a 2080 SUPER has a Phanteks AMP Series 750W 80 PLUS Gold. Should I swap the two around?

Is the i5 9400 good enough for this build? It was cheap and since this was just a basic HTPC, it didn’t matter. I do however have an 8700K in my NVR (Blue Iris) and I could swap the two around. Should I swap this, or is the CPU not going to be an issue?

Yes, I am aware the ITX board in an ATX case is going to be really weird looking. This is currently in a Phanteks Enthoo Evolv ITX which can’t fit the GPU, and has terrible airflow

Thanks!

Is it technically fine, yes
Would I recommend it, no

Your CPU won’t consume more than 100w turbo, and the graphics card Is rated for 350w but let’s say you crank the power limit to 400w

PSUs age and degrade the amount of power they can deliver and respond to, you also have other power consuming parts in the system as well

So while that power supply will work, I’d only use it as long as it takes to get a higher wattage

Sounds like throwing the 750 in there is a no brainer then, especially since I’ve decided to throw the 8700K in there too
