What PSU should i get?

I'm looking for a new PSU I need it to be 1000w or more. Specs i9-9900k 3080 and a bunch of fans and things. The current PSU's I'm looking at are: CORSAIR - RMx Series 1000W ATX12V 2.4/EPS12V 2.92 80 Plus Gold Modular Power Supply ($204.99) USD. Or Corsair HXi Series HX1000 1000 Watt 80 Plus Platinum ATX Fully Modular Power Supply ($299.99) USD. If you don't think I should get any of those please recommend me something else. Also, the power type I will be using is both 110v and 220v.

The RM 1000x is a pretty good psu. I actually have one of those in my system and it is working perfectly. When it comes to power supplies you cant really go wrong with wrong with a Corsair unit. Superflower and BeQuiet also have decent 1000W models but it all depends on your budget. 

CPU: AMD Ryzen 9 - 3900x @ 4.3GHz with a custom loop| MBO: ASUS Crosshair VI Extreme | RAM: GEIL Evo Potenza 16GB DDR4 3600MHz | GPU: Zotac GTX1080 Founders Edition | SSDs: Intel 660P 512GB SSD and Intel 660P 1TB SSD | HDD: 8TB Seagate Backup Plus | PSU: Corsair RM1000i | Case: Cooler Master C700P Black Edition

A 9900K and RTX 3080 doesn't need anywhere near 1000W. A 750W would be more than enough, and even 650W would run it.

I saw a lot of video's on this most people said after market 3080 tend to draw more power in the range of 450w with an OC i9-9900k that's about 750w and I have 9 fans in my build and light strips it all totals to 800w but I don't want to get a 850w and have only 50 spare.

What are the Bequit and super flower unit's? Are they better than corsair? If you were me which one would you get?

...no, a 3080 will likely PEAK at about 400 even under a decent OC and that's peak draw, not sustained. And your RGB strips and fans are completely seperate from your other components in that they are not on the same voltage rail (at least I'm aware). A good 850 watt gold unit is far more than enough even with all that stuff as you will likely be under 750 watts even at peak and probably sustain about 650, 700 tops. You do not need a 1000+ watt PSU.

The Gigabyte Eagle draws around 338W so only 20W more than the founders edition. The Kitguru review is running an i9 10900K @ 5.1GHz on all cores.

 

If you look at total system power draw it is 475W when running 3D Mark Time Spy.

You aren't running your PC at 100% CPU and GPU load, are you ? 750/850W PSU is fine. Corsair RMx is a good choice, be quiet! Straight Power 11 Gold (not Platinum) and Super Flower Leadex II/III are too. We also have a PSU tier list here pinned at the top, take a look.

Tag or quote me so i see your reply

So the price difference between the Rm850 and 1000 is little does it hurt my PC if I get the 1000? Also, the reason I said 1000w is that when I told someone my build and that I will have 9 RGB fans plus 3 light strips plus an AIO with a 3080 and an i9-9900k they said that my PSU will short circuit and or die faster.  have done many builds before but this will be my first build with a lot of fans and RGB. Thank you for all the help!

Well, it seems like you're just absolutely set on going with 1000W, so what's the point of even arguing about it anymore?

No, going with the RM1000 instead of the RM850 won't "hurt your PC".

My advise is to go bigger now than not have enough...then you'll be spending more money for a bigger PSU in the future because you screwed up and got one that can't meet demands a couple years down the road from now.
