Power consumption

[Curioisman]

So I have been thinking, and I seek answers.

 

Okey so I have a gtx 1650, the no external power model, and motherboard ideally cap at 75w power to PCI-E slots right? but the manufacturer recommends a 300w psu minimum for the card, why is that so, My own personal cpu (i5-9400f) has a TDP of 65, idk if it uses 65w or 75w, but adding all those up, 75w+75(?)w = 150 and adding to that like the other extra stuff, ram storage keyboard etc. adding like +30, so it would be 180w, why wouldn't some1 want a 200w psu or 250w. I am just thinking.

 

P.S I did just order a 750w power supply and a new case to make my current pc more future proof.

The graphics card manufacturer doesn't know the rest of your system specifications. While you have an i5 9400f CPU that only draws 65W someone else might be using the same GTX 1650 in a system with an i9 11900k which can draw 150W+ which would increase the overall system power consumption.

Take the power supply recommendations provided by the graphics card manufacturer with a grain of salt, they're basically meaningless as you can't determine the power requirements of an entire system based on only one part.

The GPU manufacturer has no idea what system you're putting it in, so they err on the side of caution. 

 

Similarly how you did when you bought a 750w PSU incase you have more stuffs or better stuffs later.

I see makes more sense, I just had to be more sure because I originally had a prebuilt pc with i3 and gtx 1050, but I never really upgraded the PSU and if I remember right it was something like 150 or 180w PSU, so back then I upgraded the parts whit matching power consumption, both have no external power cables and same power consumption

Hotter your climate in the world, the more power you are likely to use, GN explains it as....using up to 4% more Power per increase of 10*c or something like that.
