- I'm running 1200w on my 5090 + an undervolt / OC . 1200w is sufficient even without the undervolt so with an undervolt there's plenty of headroom.
- Just got a 1200w PSU, hopefully that’s enough.
- 1200 should be fine, you don't need a 1500W psu
Cons
- 1200w overkill, 750w be fine

a high-quality 1200W PSU is enough for this build, with a safe margin. The 1500W is nice-to-have but not necessary unless you want that extra absolute headroom or ultra-silent operation at low load. Quality > sheer wattage, so focus on a top-tier 80+ Platinum or Titanium unit rather than just going higher for the sake of numbers.
