    With efficiency in mind probably 1300w.

    I use an Asus Thor 1200W (3090 KPE + 10900K 5.3GHz) in gaming I see around 650W total and in benchmarks close to 800W.

    3090 kingpin draws around 480w while 5950x draws around 200w if you oc it. Plus other system components, I would say the whole system sustain power is around 750W
    Since most power supply at best efficiency at half load. I would suggest a 1300W or 1600W power supply. Since you are going to run 24/7, I would suggest a Titanium power supply.
    I think EVGA SuperNOVA 1600 T2, 80+ TITANIUM 1600W would be a good choice.

    Get something with high efficiency (Titanium or Platinum) that's in the 1000W+ range and you should be gravy.  Make sure it's quality unit.
    If the eVGA P2 1200W was in stock anywhere I'd highly recommend it, I've had more for a few years now & it's powered all kinds of setups ranging from SLi Titan Xp's to a soon to be Kingpin setup.
    I think going with a 1600W would be some expensive overkill, but you would be right in the half-load sweet spot most PSUs have in their efficiency curve.  But if you get a Titanium or Platinum unit, it should be very efficient at any load ranging from 50-100%.

    I have been happy with the 1200W P2 from EVGA but it's almost impossible to find right now.

    same, psu have 90% efficiency at 50% load, 1300watt is the best choice

    I would personally not get an EVGA or Corsair PSU I would go for a 1000w or Higher titanium from enermax, cooler master, or seasonic. I have had issues with my 1000w evga p2 psu and I have 2 of them in 2 different systems. I have also had some questionable issues with Corsair.   I have a new enermax platinum 1050 and it has had no issues with 1.43bios vcore 10900k and 3090 ftw3.
     
    Alot of people here will say EVGA PSU but I wouldn't buy another one.

    Hey guys, also going to have a K|NGP|N and a 5950x in the near future. If the estimated wattage is like 800W, can someone explain to me why you all are recommending 1300+ W? Is it because 800W is the bare minimum and the system almost always draws more than that while in use? I understand the headroom to OC parts but, a 500W headroom seems like a ton.

    2 1080's SLI
    RIP nVidia SLI Driver support jan. 2021, so future owner of a RTX 3090 K|NGP|N
