Hello, I'm trying to figure out the right power requirements for my new build, but the numbers from different sites seem inconsistent.
I understand that buying 1000W might be sufficient, or perhaps I'm misunderstanding how it should be calculated.
I prefer efficiency and would like a bit more than just the minimum needed for future upgrades.
My planned components are:

GPU
Sapphire nitro+ 7800XT
CPU
7 7800X3D
MOBO
Asus TUF Gaming X670E Plus
SSD
WD Black SN770 2TB gen4
RAM
G.Skill Ripjaws S5 6000 2x16 CL32 white
PSU
Lian Li SP850 SFX 80 Plus Gold
Gigabyte UD850GM PG5 80 Plus Gold 850W (about 104 euros)
CASE
Lian Li O11 AIR MINI snow
COOLER
DeepCool AK620

I'd also like advice on whether the Lian Li SP850 is a suitable PSU.
Would an 850W unit be adequate or excessive? I'm still unsure if my setup truly needs 1000W... it doesn't seem like a top-tier GPU/CPU build after all.
Any suggestions for improving the build would be greatly appreciated.
Thank you!

Everything looks fine.
Just a note, if you have extra wattage beyond what you're using, you'll end up more efficient, especially by examining the efficiency curve of your PSU. A 1KW unit can help delay the need to replace it during future upgrades.

Hope that was a typo regarding the motherboard, as the 6xx series is required for the CPU.

I don't see any benefit in purchasing a PSU sized for SFX when your case accommodates ATX PSUs. Power supply calculators are extremely precise. If you understand the requirements, you might find what you need now. A 750w unit could suffice at present. A PSU functions best within its middle range of capacity. It only draws the power it requires, not more than its maximum. This suggests opting for a more robust PSU than necessary. The main drawback remains the expense.

Thanks for the feedback. I hadn't considered the significance of the sfx. I'll adjust it to something more substantial. I'm moving toward a dual chamber design just for this purpose.
