Advice for PSU with a new PC build

[Stayle]

Hello everyone, I'm currently building a PC and one of the remaining components is the PSU/Power Supply, I need to ask for advice.
I'm currently leaning to the Corsair RM850x Gold or maybe the RM750x gold, if the RM850x is way too overkill.
Also if I buy the RM850x, does it mean I'll use more energy in the end ? So my electricity bill will be more expensive than buying a RM750x.
Sorry, I have no knowledges about that kind of stuff.
This new pc is for gaming and streaming as a main usage, but also encoding videos, and editing pictures/drawing primarly .
I also plan to upgrade when the new Nvidia 3000 series get out and in two years I'll probably upgrade for the new 5000 AMD series.

This is my PC specs:

GPU : RTX 2070Super 8 GB
CPU : Ryzen 3900x
Cooler : Noctua NH D15S
RAM :32GB Corsair Vengeance LPX 3200
Motherboard : Asus TUF X-570 Plus
Storage : Sabrent 1TO, Saegate hard disk 8TB
Case : Fractal Design Define R6
Case Fan : Not sure if I'm planning to buy a set, or using the case fans, but in the end it will be 3 fans, either 120mm or 140mm.

Peripherals:

Dual monitor 24''
Webcam : Logitech G922
Microphone : Blue Yeti
1 mouse
1 RGB Keyboard
1 headphones
1 osu tablet

Thank you for the help in advance !

The amount of waste wattage between the 2 will be negligible as they're the same efficiency you'll just be at a slightly different point on the curve.

If both psu are close in price I'd opt for the 850.

I would buy a seasonic Focus GX over either though I personally hate the RMX cables more than any other similar psu line.

Thank you for the info,
I'll look at the seasonic too.
Now I'm thinking, would be a 650w too short for my usage?

 

[oxrufiioxo]

With a high quality unit it will be fine. I would still opt for a 750w unit though to give you slightly more headroom for future GPU/CPU upgrades.

Thanks, I was browsing the forum, and saw someone said the Corsair Vengeance 32GB wasn't a good match with Ryzen ? Is it true, what is the issue with that ?

Sorry for too many questions.

No problem, I think the issues is corsair more so than other ram vendors changes revisions rapidly so you end up in a scenario where one kit works great and another won't even boot. It's more of an issue with older kits.

Oh I see, I bought this one https://www.amazon.co.uk/Corsair-CM...97121&sprefix=corsair+ven,aps,169&sr=8-1&th=1
Should I change it ?

I don't expect you to have issues but you can always switch to something on your boards qvl if you're worried about it.

True, I will try atleast to put on my motherboard and see it, it should work fine. Thanks for the help, I can finally buy my PSU !

Both are a great choice TBH....I personally like Corsair, but Seasonic has great quality as well. I have the RMx 750 and i did not like the cables as well, so i just had custom ones made for me.
