Pc configuration good, what can I improve?

What can be improved, the GPU should definitely be an asus, and only asus and Corsair. I'll buy the pc when the prices fall, limit 2 euro (wait until everything falls that's why it's so expensive) I want to play with the pc but also stream a lot and all games (Minecraft, Hel let loose, Train sim world) on highest settings in WQHD, or maybe even play 4K with mid.60 FPS

CPU: 5 5600x

GPU: Asus Tuf 3070 oc

CPU cooling: H115 Elite capellix (Corsair)

Mainboard: ASUS Rog Strix b550 e Gaming (need wlan)

Power supply: Corsair RMX 850w (no 750 because permanent 90% utilization, and hardly any Auffüstoptiomen

Housing: Corsair 4000x or Corsair carbide series delta rgb (graphics card should be vertically mountable), rgb lighting controllable

RAM: 32 GB dominator platinum 4x8 GB

Ssd: Corsair FS MP600 per 1 TB

Hdd: seagate barracuda compute 2 7200rpm as a data grave

Monitor: Gigabyte G27QC, wqhd for 319 euro

would get the PC for Christmas, and if it is too expensive buy the missing parts and monitor on my birthday (March), the system should go through Corsair

iCue or asus Aura can be controlled.

Why not a Be Quiet! Power supply and case? They are the best

Your configuration looks very good. There are only 1-2 things that bother me a little (your opinion may be different):

A mainboard with Wi-Fi is unnecessary. You can just buy a motherboard without Wi-Fi that is better (no Wi-Fi for the same price) and buy a 5 euro Wi-Fi stick later. It does the same job as the mainboard WLAN and that for less money
2 * 16 GB While theoretically better. In the end, it's your decision

Otherwise the configuration is perfect. Hope for you that by then you will get the parts for the normal price and not spend too much

The configuration is quite solid. However, she has some room for improvement:

The beQuiet Straight Power 11 650 watts is easily sufficient for the power supply
A good air cooler (beQuiet Dark Rock 4 Pro) is sufficient
A cheaper Kingston A2000 is easily sufficient as an SSD

A 650 watt power supply is by no means sufficient, for overclocking and other things, I don't have any upgrade options without having to replace the power supply. According to be quiet, my PC consumes about 700 watts. I'm also a fan of RGb, and water cooling is the most effective, and the fan would hide the mainboard's lighting

I'm still thinking about the 2. 4 sticks simply look better from the rgb than 2;) but thank you very much for the rating

Of course that's true. Also believe that you can easily get there with 32 GB.

And a pc is only as fast as the slowest component, so a cheap Kingston makes no sense, but thank you for your answer

Maybe even at 16 but I don't want to risk that.

BTW because of you I have now changed the power supply to be quiet

Because I'm a RGbist and a comfortable is out of the question for me, not with the case, power supply I would still have to look
