Digging Into the Electrical Cost of PC Gaming
New submitter MBAFK writes "My coworker Geoff and I have been taking power meters home to see what the true cost of PC gaming is. Not just the outlay for hardware and software, but what the day-to-day costs really are. If you assume a 20 hour a week habit, and using $0.11 a KWH, actually playing costs Geoff $30.83 a year. If Geoff turns his PC off when he is not using it, he could save $66 a year."
Running PC games can easily take 300-500W with a high-end graphics card. Posting on Facebook probably uses 30-50W on a modern desktop PC (plus whatever the monitor uses in both cases).
