For comparison, 445 Watt average continuous is enough to heat my office in winter to a nice -& comfy temperature, I don’t need central heating in that room when hashcat is running for many hours.You might wonder if 445 Watt is enough for that, given that electrical heaters typically come in 1000+ Watt models. But electrical heaters don’t consume electrical power constantly to heat a room, they have a thermostat that shuts of current flow regularly when the desired room temperature is reached. They are more powerfull so that they can heat up a room faster. While my desktop computer requires 445 Watt continuously when cracking with the GPU.Didier Stevens Senior handler [blog.DidierStevens.com](http://blog.DidierStevens.com) Keywords:[0 comment(s)](/diary/Password+Cracking+Energy+More+Dedails/31242/#comments)
