Heat ?

[theam123]

Hello.

 

I'm considering getting a 650w because of a good offer that I got.

I got a single GPU and the system I got really only needs a 500w. 

Will a 650w produce more hear than a 500w, and why ?

It won't. If you look at the efficiency curve, the 650w will actually produce *less* heat than the 500W

This is why you should always get a PSU that's 100-200W above what the TDP of all your components needs

Also it leaves room for expansion, you won't kill your system if you miscalculate, etc.

Nope.

Your psu will only use as much power as needed. Modern units won't even bother ramping up the fan unless you are really stressing it
