Good question, a gaming PC can consume lots of electricity while running, but the specific wattage highly depends on your hardware. Salad will run your GPU at peak performance, so find the power consumption for your particular model. For example, an NVIDIA GTX 1070 uses around 150W at peak. Assuming that you pay 10 cents/kWh, running it for an hour would cost you ~1.5 cents.
Luckily, Salad’s hourly earnings should outweigh that cost for the 1070, but this might not hold true for every graphics card, or every electric bill. So be sure to check your local electricity rates and compare these costs to your earnings,and this is not in our best interest, but a competitor of ours has a really nice profitability calculator to help you with the math! nicehash.com/profitability-calculator.
