You have a maximum power supply of 600W, you can assume for a simpler calculation that it consumes 500W at the maximum load, you have such a load 7-9 hours a day. Treat the rest that it uses 300W

As for me, a pointless question, because for about PLN 40. You can buy a wattmeter, which is enough to connect, extend to which the computer is connected with the monitor and you have already got a reliable measurement, even converted into kilowatt hours, and knowing them is not a problem how much money you need to add to the bill through such a computer. It is impossible to estimate this, the more that each energy company has a different rate, so this amount will vary depending on the energy supplier.

This is estimated to be around 5kW a day x 30 days a month. You have the price per kWh + transmission costs on your energy bill. The calculations are rough and a little overstated but you have the magnitude of the problem.

Why make such nonsense assumptions? First, the 600W power supply will consume more than 600W at maximum load - to deliver 600W on the secondary side with an efficiency of 85% it will consume about 705W from the network. The components of this computer will NEVER pull 500W off the mains. When browsing the pages, the power consumption will be much lower than 300W.

If you go the easy way, you can use someone else's tests. XFX HD6950 1GB + I7-2600K is a fairly similar platform in terms of power consumption.

With a load of 250W, we have 67W at rest. The tests of the power supply show that it will have an efficiency of about 86% at 250W, at 100W, about 85% (for the sake of simplicity, it can be assumed that it is usually about 85%), so the platform will consume about 294W at maximum load, about 79W from the socket when loaded. when walking on the pages.

Such calculations are best done by measuring the unit's current consumption with a wattmeter in two situations: under load (game) and without load (desktop / www). Theoretically, you can try to calculate it all roughly (assuming a certain error in these calculations).

The hour of playing games (I incorrectly assume the maximum load all the time, so it will not work worse) is 294Wh (let's count 300Wh), i.e. 0.3kWh. You play 5-7 hours, so it will use 1.5-2.1kWh of energy.

Walking on the pages and watching movies is a rather low load, you can count 80W rounded, i.e. after 0.08kWh it will be consumed. Let it be 0.1kWh.

So it can be assumed that you will use 2-3kWh per computer per day. For a month, with these assumptions, it will be 60-90kWh. I do not know exactly how much electricity costs (due to the transparent pricing policy of my supplier), I estimate about 50-60gr / kWh (including all possible fees, i.e. dividing the invoice amount by the actual consumption without thinking). So a month I would shoot that it would be PLN 30-50 on the electricity bill.
