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."

      Yeah every now and then Slashdot has these silly articles about PC power consumption, "kill a watt" etc.

      The power consumption of modern PCs (post P4) has gone down to a level where most home users would usually be better off looking for savings in other areas. Driving more efficiently, not using as much cooling/heating (and making it more efficient - insulation, sealing etc).

      As for gaming, sure a high powered gaming rig will use a few hundred watts (and usually less if you're not doing SLI). But that's far from the most energy hungry way of having fun. Your hobby could be drag racing, or hiking/rock climbing somewhere that requires a 1 hour drive, or even baking cakes. FWIW even cycling and other sports might be more energy hungry if you replace the calories burnt by eating more of stuff that requires a fair bit of energy to produce ( e.g. US corn fed beef).

      From various sources:
      1 pound of beef = 13-15 pounds of CO2 ( http://www.usatoday.com/news/nation/environment/2009-04-21-carbon-diet_N.htm )
      1 kWh = 2.3 pounds of CO2 ( http://cdiac.ornl.gov/pns/faq.html )
      so 1 pound of beef = 5.6-6.5kWh

      So if all that exercise makes you eat an additional half pound of beef (400kcal), that's about the equivalent of running a 300W gaming rig + monitor for 9 to 10 hours.

      In contrast 1 pound of chicken = 1.1 pounds of CO2.

      I've even seen many people here who say they still prefer to use incandescent lighting. It doesn't take that many bulbs to use as much as a gaming rig, even fewer for a facebook/browsing PC/notebook. A single fluorescent tube lamp uses about 40W already.

    What about switching out power hungry gaming cards for newer, more efficient cards? This year's mid-end model may have comparable performance to last year's mid-high end model but might draw half the power. Over time, the lower power consumption adds up, not to mention you can get by with a smaller power supply. Likewise, trading in your hard drives for a solid state drive (maybe using a green HDD for extra storage)? And for old timers, switching out CRTs for LCDs? Overall, I think it'd be easier for people to upgrade to more energy efficient components than it would be for them to change their PC usage habits. Lowering the sleep/HDD shutoff/monitor shutoff timers can make a big difference too without having to remember to shut down your PC every day or waiting for it to reboot. Not an option for everyone, but gamers usually aren't on a shoe-string budget or else they wouldn't be able to afford the PC and the games in the first place.

High end gaming machines put out a lot of heat too. Since many gamers are using SSD's these days, sleeping your computer is great, they resume so fast. It's just common sense. I make sure everyone in my house shuts down or sleeps their machines at night if there is not a valid reason why they are on. It really does help. The real problem with this list is where is the spec list? That dual or triple GPU machine, that is water cool, and has a huge overclock will use a ton more power then your i5, single GPU machine.

    Considering that yearly electricty bills routinely reach about a $1000+ for a standard household, this added 10% due to gaming is pretty insignificant when compared to other hobbies...like racing cars for example.

    Sure, there may be cheaper hobbies, but I honestly don't think anyone well-settled enough to be practising a daily hobby and deriving enjoyment from it finds it a problem to spend 8 bucks 50 cents a month for their recreation.

    I have a meter as well; one thing to consider with replacement appliances is the reliability and longevity of the appliance.

    I have a 33 year old Sub Zero built-in refrigerator in my new house. It's so old that it has only one knob for temperature adjustment, and the refrigerator compartment on top is slave to the freezer setting. I've removed the cover to the compressor and coils to clean them, and I've found some indication that a service or two have been performed over the years, but compared to a friend's brand new LG unit that's had to be serviced twice in eight months and had cost them $1600 to purchase, I'm happy to use this fridge for the moment. Plus, a new built-in refrigerator will cost between $4000 and $8000 depending on what brand and features are chosen. This unit can run for a very, very long time for $4000 worth of electricity.

    As for TVs, one doesn't necessarily have to use the fancy, big TV all of the time either. For many years I had a projector screen that could roll down in front of the entertainment center, blocking the 27" TV in it, so I could use my projector when I wanted to watch something of substance. Now, I have the projector in a different room from the TV we watch the news on, and we only use it when we actually want to watch a movie or some other thing where surround sound and a big image matter. Obviously the roll-down method won't work with a fixed TV, but putting the fancy home theatre TV into a different room would.

    My current PC (an old Dual-Xeon box) has a hardware sleep switch that ties into some pins on the motherboard, and when pressed the computer drops down to a low power state. When I'm done using it I just put it to sleep, and when I want to use it again it comes back in about three seconds. Works well, keeps all of my programs running fine, and saves power.

    There are lots of techniques that can be used to save power, but the biggest hogs in the house (HVAC, hot water heater, refrigerator, oven/range/cooktop) don't hold a candle to the consumer devices that everyone always panics about. If you want the most bang for your buck, insulate your house. Change your windows. Plant some trees that increase shade on the structure. Turn your thermostat up a couple of degrees and install some high efficiency ceiling fans to keep the air moving a little. Sure, turn off the electronics you're not using, but don't assume that it'll be earth-shattering on your power bills just by doing that.

    My home has on average 100 watts of power available. I can use more in the short term, but doing so depletes the battery and means I'll have to use much less for some part of the week. The wind turbine which is my sole source of power is rated at 750 watts, but only generates that much in absolutely perfect conditions. So I know quite a bit about how to use power economically. I can light my whole house effectively with just 18 watts of LEDs. They're strategically placed, yes - but you can easily read more or less everywhere.

    In this situation, the graphics card on my computer (Radeon HD 6850 at 127 watts TDP) is actually the biggest power drain I've got. Obviously, my gaming is limited to two or three hours a day... Power is worth thinking about.
