Question Which Power Supply do I choose ?

[Alxe66022]

I am new to the world of PC builds and finally I am building my own one. Since I will use it mostly for gaming, game developing and graphics design, what would be better between a Corsair RM850i or Asus ROG STRIX 850w?


My build until now is this:


CPU: AMD Ryzen 7 9800X3D
COOLER: ARCTIC Liquid Freezer III 240 A-RGB
MB: Asus PRIME X870-P WIFI
GPU: Gigabyte WINDFORCE MAX OC GeForce RTX 4070 Ti SUPER
RAM: 4X Corsair Vengeance RGB 16 GB DDR5-6000 CL30
STORAGE: Western Digital WD_Black SN850X 1 TB M.2-2280 PCIe 4.0 (I will buy one more)
CASE: Corsair 4000D Airflow ATX Mid Tower Case

Good luck finding very much technical information on power supplies. Almost every thing else computer related you can find very detailed recommendation from many location. Power supplies you are lucky to even find a independent review that has independently collected data. Most are just re posts of information from the company marketing material....and some of the lesser known companies tell massive lies.

Making this even worse is the manufacture will sometime change the parts used inside but keep the same part number on the outside.

There is also the problem of so many models and so many submodels with very similar names.

I suspect either of those is fine. Neither company really manufactures themselves. Corsair more than Asus is known for power supplies but Asus is a big company so they likely have their own design engineers.

The only real comment I have is why are you looking at liquid cooling. If you look at pretty much any of the cooler test reviews from the last almost 5 years air coolers have improved a lot. Unless you are going to go to a 360 aio their are lots of air coolers that will actually exceed 240 aio for a fraction of the price. It is more a air cooler the worst thing that can happen is you need to replace a fan. AIO will eventually fail even if it is just the coolant evaporates though the lines and there is no way to add coolant.

do you have the parts for this build already at home or just planning on buying them for now ?

first thing - don´t buy 4x 16gb sticks of memory ,
but rather buy 2x32gb or 2x24gb or 2x48gb combination
(depending on how much memory is needed for your work) -
it is not adviced to have all 4 slots populated , that way you can run into all sorts of issues with a memory controller on your motherboard and 4 ram modules may have problems running at full speed .

9800X3D is great for gaming but not so much for anything else
depending on how serious you are about your work or how much time you spend doing
developing and graphics design you may consider getting a different cpu maybe ...

both those power supplies are good -
rog strix is made by seasonic and it is atx 3.0 certified
and therefore better equipped to deal with modern graphics cards
but this unit is usually pretty expensive in most regions

RM850i is made by CWT and it is an older unit - meaning it is not atx 3.0 or 3.1 certified -
i would not buy it brand new , if you want to go with corsair try to find RMx 3.1 (2024) revision ,
or at the very least RMe (2025) .

where are you located ?
what is your budget ?

Firstly I'd like to second not buying 4 sticks of DRAM if you plan on actually running 6000.

Hardware Busters is a very good source of testing and hardware information: https://hwbusters.com/best_picks/best-atxv3-pcie5-ready-psus-picks-hardware-busters/4/
