Does a 650W PC power supply always use 650Watt?

With normal use such as Surf the Internet, watch Netflix, use YT, Office and so also 650W or only when playing games where it is very strenuous.

Fl

650 watts is the maximum that is output, so you usually never get this value.

In principle, the power pack is just a distributor and regulator. It only takes what it takes plus a small excess as a hedge. The 650watt are just the maximum output.

Sy

No, this is the specified performance that the power supply unit can bring when it is loaded.

Am

How much would he take with e.g. Watching Netflix or surfing the internet

Sa

As many watts are "used" as are required by the system. The 650 watts are the maximum that the power supply can provide.

Si

Depends on the components. It always differs, for CPUs with integrated graphics units, this can be less than 200 watts. The problem is that a Cpu has a basic consumption. Laptops are often more than just under 100 watts or under 50 watts.

So: CPU: AMD FX-6300, 6 x 3.5GHz

Graphics card: nVidia GeForce GTX 950 (2GB GDDR5)

How about that then?

Wtf your power supply is completely exaggerated, your CPU draws 95 watts and your CPU 90 watts. So you probably come in and of itself. Over 200 watts, which is nothing. If he is really not under load etc. I think that you are on 100watt. With good active cooling, probably even less.

Is it bad that the power supply has 650w? So does it make a difference?

(Isn't my PC, one from eBay)

Definitely not. I even have an 850 W power supply in my computer. Do you seriously believe that I would have gotten one if that was the constant consumption? The only purpose is to ensure that the computer is still adequately supplied even under maximum load.

You should pay attention to the maximum consumption of the individual components and then choose the power supply so that there's still some reserve, otherwise in the worst case it can happen that the computer is restarted when it is doing the most demanding things because the power supply does not provide enough power so that it can do everything it should.

In the worst case, the power supply unit may be so overwhelmed, especially when the system is under maximum load, that the internal fuse blows, which then leads to the computer being as if it had been completely switched off at such a moment. What that means for HDD hard disks, namely a probable hard disk crash, from the lack of cooling of the CPU (main processor), GPU (graphics processor) processors - where the main processor always has its own cooler, the graphics processor at least also with good graphics cards accordingly own fan is actively cooled) and secondary processors not to mention. Therefore, you should always make sure that the power supply unit can deliver at least a little more power than the computer with all its components can use under maximum load.

If, however, the full power is not required, the power supply unit only supplies the computer with the power that the computer needs at the time.

No, dog even better because you now have good upgrade options
