What happens if your laptop uses more than the provided 65W charger adapter without the battery?

[Microsoft Windows 8]

I am just curious. My laptop charger is rated for 65 Watts output.


I am now going to create the most ridiculous scenario:

What if, I wanted to play Crysis 3 at Ultra 4K settings. It would max out the GPU, (GeForce 840M)
30W is used.

Say, I was also playing a game using integrated GPU, (Intel HD 4400) 10W from what I've seen.

If I also wanted to do CPU benchmarking. Maxing out the CPU (i5-4210U), Its a 15 Watt CPU, and with the Integrated GPU maxed out, It would be using 25 W.

Display at Full brightness. Maybe 3-5W

If I was also burning an image to DVD, Another 5 Watts.

Random/Sequential Writes to 3 External HDDs, Probably 10W


Would be about 75W. What if I was using my laptop without the battery? then the Charging adapter alone would have to give my lappy 75 W instead of the rated 65W

What would happen? Would my laptop shutdown? Or will the charging adapter fry out?


On idle, my laptop uses 4-5 Watts. In gaming, 30W

Problem is you'll never be able to make the laptop draw that much power.

Would so! (Taking in to account the enormous amount of time I will need)

Why ever not? Maybe it would thermal throttle, but still, what if I decided to charge 3 iPads all at once on my USB ports?

Because you presume the CPU can keep too many things can active at the same time. Try it and you'll realize the laptop is designed not to exceed the PSU rating.

Laptop's don't HAVE a PSU, although it may be considered the charging adapter. Using OpenHardwareMonitor, CPU wattage may go up to 25W. GPU TDP is 30W, and my laptop surprisingly never thermal throttles.

Without a battery, the charger is the PSU (you obviously know what I meant).

Well, yes, and no for the last part.
