71-90K Need advise for components to build a new high end gaming and productivity system and need tips/guides for windows and bios optimisation.

[OMEGA44-XT]

I will soon be getting a RTX 4090. I have a 13700k cpu, Gigabyte Aorus Master Z790 motherboard, DDR 5 (16x2gb) 6400mhz ram, three noctua fans, NHD15 cromax cpu cooler, 24” Viewsonic monitor
Which converter you suggest I get for the 16amp plug.
Did you see the image I posted of the MX converter.
Also please check out the link, it’s a different product but looks like it should also work.

I used an el cheapo converter, nothing branded. IMO it should be fine. You need to 15A to 5A converter, that's all.
