So office and so? How much more than a laptop? With i5 3470 processor?

Can test with NEN electricity meter ^^

This generation - with the internal graphics around 20 to 40W - with a dedicated graphics card 30W to 50W.

I guess 80W

Wr

That's a lot

On
PC with a modern multi-core processor from Intel and a dedicated graphics card consumes around 135 watts per hour. With four hours of operation a day, this corresponds to an annual one
Power consumption of around 200 kWh. At a kWh price of around 30 cents, that's around 60 euro.

Mine runs almost 24/7

A laptop doesn't even need 15 watts including a monitor

It depends on the laptop, which can use 30W an hour.

As someone wrote above, it's best to measure it. We learned much higher values in school, but the technology wasn't that advanced.

You really have to consider whether a PC is worthwhile or a laptop is better because the monitor also consumes 30 watts

Of course, it depends on the area of application.

Think about the old tube monitors / televisions, what they used up. A lot has really happened there.
