PSU for 14900k & RTX 4090 (audio/3d/gaming)

Hey y’all, just looking for some PSU advice here! I’ve got parts coming in for a music production / 3d rendering / gaming build as follows:

  • Intel i9 14900k
  • PNY Verto XLR8 OC RTX 4090 (450w limit)
  • G Skill Ripjaws 2x32GB 6400
  • Arctic Freezer II 420mm AIO (top exhaust)
  • 2TB Samsung M2
  • 4TB Samsung M2
  • 4TB Samsung SSD
  • 3x 140mm Corsair front intake
  • 1x 140mm Corsair Elite exhaust
  • 4x 120mm Phanteks T30 side intake
  • Arctic 10x fan hub
  • Corsair 7000D Airlflow

I’m looking for a reliable PSU for this build even after scouring the net as one does. I’ve got a be quiet! Dark Power 13 1000W on the way as it is an “A tier” PSU and found it at a good price.

 

Since ordering, I read up on voltage spikes and the 1.5x (or +50% GPU) wattage overhead recommendation.
 

My question is: am I good with the 1000w ATX 3.0 Titanium rated PSU that I’ve already purchased? Calculators suggest my components draw a peak 900~1000W, and I could only envision that scenario for rendering (and obv benchmarks) which would be my use case maybe 5% of the time. My understanding is that the ATX 3.0 handles the potential transients even though my particular GPU is limited to 450w. Will the Titanium put me in good hands with its higher efficiency at higher loads or should I opt for 1200/1300/1500W?

 

I have had my eye on the Corsair HX1500i as well as the RM1200x Shift as they are higher wattage, both ATX 3.0, and have a similar 10 year warranty like the be quiet! I have on the way. That said, these are lower efficiency if that matters much; I’ve heard it doesn’t.

 

Thanks for any and every insight! H

Imo the Plat and Titanium rated PSUs are all very overpriced,  the additional 2% efficiency is useless, and they cost like double a Gold one !

You'd better with a Gold 1200W like the PP12

most definitely. The be quiet units at the high end have never had problems with transient power spikes, and the 40 series is a little lighter on transient spikes than the 30 series was.

I WILL find your ITX build thread, and I WILL recommend the SIlverstone Sugo SG13B

Draws 400 watts under max load, for reference.
