Question Is 650W PSU enough for a R7 5700X & RTX 4060?

[FoxBat25]

I would like to know what kind of PSU Wattage should I get for a gaming PC i am building.

CPU: AMD Ryzen 7 5700X
GPU: MSI RTX 4060 VENTUS 2X BLACK 8G OC
Motherboard: Gigabyte B550 AORUS ELITE V2
Cooler: NZXT T120 RGB
RAM: XPG SPECTRIX D35G 16GB 3600MHz DDR4 x 2
SSD: M.2 x2
HDD: 2 HDD x2
Case: NZXT H5 Flow RGB

PSU: I am thinking Cooler Master MWE 650W V2.

*Which* MWE 650W V2? There are several, and they range from decent to junk.

Cooler Master MWE 80PLUS Bronze 650W V2

The full range or the 230V only? The latter is much more cheaply made even beyond being 230V only.

The full range one is OK-ish, as it's a decent budget one but I'd personally not pair it with such a modern platform. The 230V only is a definite, bright red "no."

Why need so much wattage? I put your system in psu calculator and it only need around 450w or more. Is there something I'm missing? I'm a beginner correct me if I'm wrong

For several reasons. One of the most important reasons is headroom (someone may want to upgrade and/or may not want to run PSU at higher loads where there may be less efficiency). Another is that there are very few quality PSUs below 550-600W these days. Many of the costs for a PSU are fixed (the employees, the real estate, the marketing, the shipping) so it's a hard sell to market a quality 400W PSU that will cost almost what the 600W does.
