PS3 Slim uses half the power of PS3 'Fat'

Sony heralded the new PlayStation 3 Slim as more energy efficient than previous models, but that's an easy feat considering the older PS3 'Fat' models were some of the most power-hungry home video appliances available, with power consumption similar to that of a 50-inch plasma TV, for example.

To test Sony's claim, we put the PS3 Slim through a battery of power consumption tests and the results really are impressive: the PS3 Slim generally uses less than half the power of the original 60GB PS3, no matter what task it's performing. Check out the comparison:

All measurements in watts.

Whether the PS3 Slim is a "green-friendly" device depends on your perspective. As you can see from the chart, the PS3 Slim still uses much more power than a typical standalone Blu-ray player like the Samsung BD-P3600, so if you're going to do mostly Blu-ray playback, the PS3 Slim is a real power hog. On the other hand, the Xbox 360 uses about 187 watts while playing a game, which makes the PS3 Slim look like the HD game console for the environmentally conscious. The Nintendo Wii uses a paltry 19 watts, but is standard-def only.

If you've got an older PS3, you might be wondering how much this extra energy consumption is going to cost you over the course of a year. Unless you're playing a lot of video games, the difference isn't that much. If you generally play for about 20 hours a week, you'll save $13.74 per year using a PS3 Slim vs. an older model. If you're hardcore enough to rack up 50 hours of gaming per week, you'd still only save about $100 over a three-year period. In other words, the PS3 Slim may make you feel better, but it won't make much of a difference in your bank account. (Our cost estimate uses the average price of energy in the U.S. during 2008, which is 11.4 cents per kilowatt per hour according to the Energy Information Administration.)

Wow, quite impressive. If they add in ps2 backwards compatibility via firmware download I will upgrade. The way I see it, it will take up less space, runs quieter, runs cooler and uses half the power. I want a second bluray player for my upstairs living room, I would be more than willing to use my 'fat' ps3 for the living room and a slim in my theater room. But given I own 80 ps2 games in which I still go back and play quite often (God of War, Ico, Shadow of the Colossus, Sly Cooper, etc) I am not giving up BC. And before anybody starts in with "buy a ps2" crap. I don't want yet another console, more wires. Not too mention I have no desire to go back to memory cards and wired controllers. Playing ps2 games on my 'fat' ps3 in the living room, isn't much of an option, 32 inch TV vs 58 inch. TV speakers vs 5.1 surround sound. Not too mention the living room TV gets used with the family, not a place I can game in. Overall I love my BC ps3 (original 60 GB hardware unit), but would upgrade if the Sony releases the update many of us are waiting for.

they couldn't add ps2 backwards comparability with a firmware upgrade , they would have to add the "emotion engine" that was in the ps2's and the early ps3's
by chrkeller August 28, 2009 4:26 AM PDT
Later ps3 units had BC without the emotion engine hardware. Sony has emulated ps2 BC before, they can do it again.

Seriously?? Backwards compatibility is still a major issue for the 2 or 3 hundred of you dumb enough to go off and sell the PS2??

The PS2 slim takes up hardly any shelf space (I have mine sitting on my HTPC and PS3 slim sitting just below that shelf), and if you were smart, you would have picked up a couple of Logitech wireless controllers for the PS2, it makes life much easier. And as far as "more cables" go, the component cables that I have on my PS2 are the ONLY component cables in my setup, hardly adding anything to the 3 HDMI cables I currently have running to my tv. As far as that goes too, clean up your damn cables you lazy bastards, wire ties at "The Shack" are literally dirt cheap and make stuff much more easier to manage. And for the "memory card" issue, slap 2 original Sony's in and forget about it. Were you all the same people that complained that you couldn't save your PS1 saves to a PS2 memory card? Go whine to Sony directly on their forums, not here on Cnet, Digg, Engadget, etc, we are all tired of hearing it.

I've never owned a PS2; I've always played my PS2 game on my PS3. I only own one PS2 game, but it's Okami, a major epic that I want to be able to play over again should I decide to do so. Yes, there's a Wii version, but there are reasons for keeping the PS2 original, such as the end credits (left off the Wii version).

If Sony can port PS1 games to the PS3, and they've already done software emulation on a version of the PS3 that I've already got, then it shouldn't be too much of a stretch to offer it again.

"Later ps3 units had BC without the emotion engine hardware. Sony has emulated ps2 BC before, they can do it again."

The launch PS3s have both the PS2 CPU (Emotion Engine) and GPU (Graphics Synthesizer) included on the motherboard . The next wave of systems removed the CPU, but kept the GPU. So BC was done using a hybrid between hardware and software. As a result the BC compatibility was slightly less. The current systems don't have either the PS2 CPU or GPU. There's always a chance they could add PS2 BC back in purely via software emulation (as PS1 BC is handled), but it is incorrect to state that they have done it before.

Bought a PS3 Slim last night!! I actaully went in to buy madden 10 for 360, but then I saw they had tons of Slims everywhere in the store already. Having been looking at blu-ray for quite some time, I decided to pull the trigger on the Slim.

Now that you've got one, if you have a taste for RPG-style shooters, check out Valkyria Chronicles. It made me glad to see SEGA's still 'got it'.

As to the BC issue, I own a PS2 slim and an a not-so-old PS3 [120Gb] and I suspect I'm not the only gamer in that boat. My only problem is only having 2 fib-opt inputs on my HT system, other than that, I'm happy enough [too many digital devices, not enough 'input' ports, switch boxes can only take you so far...]. .

Less power means less heat, which means less noise. Still, the PS3 Fat is pretty respectable considering the average mid-range desktop PC draws about the same. I always turn off the switch at the back of my PS3 at night so it doesn't draw phantom power.

That's pretty impressive. Do you guys know how much the later fat PS3s used in terms of power? I know they used a smaller die on the later CPU and GPUs, so I'd assume there would be some sort of power (and heat) savings with the later 80GB BC consoles and eventually the current 80 and 160GB ones.

by Absolution2009 August 27, 2009 10:44 AM PDT
Crap, I have the 60 GB model (lucky to have one that doens't make noise) but I didn't realize it took that much energy. Mine is always constantly on because while I'm at work, my roommates or their g/f's watch movies or play games or listen to music with it (we have a bose surround sound system).

When I get home, I start using it to play movies or games online. Would you guys reccommend I change from 60GB to the slim and just turn off the 60GB?

This is a comparison to the first generation Fat version though...Compare it to the refreshes and the numbers will be much closer as they shrank the fabrication process for the GPU and CPU.

I purchased a 120 GB Uncharted Bundle for Christmas last year that does not have BC. I am curious on where the power usage lines up with the analysis above. My understanding is that it uses less power than the original console, but I have to leave the door of the enterainment system open when playing a game or watching a movie.

PS3 slim has no BC for PS2 games. Read the research on Wikipedia.

Why waste the footprint space for TWO Playstations when Sony could give me everything I want in just ONE footprint? It's not a whine, it's a reasonable consumer expectation.
by Absolution2009 August 27, 2009 3:05 PM PDT
Download it on PSN!

Or go on ebay and buy the original 60 GB model while you still can. People are still selling it and it's less than what it cost when it first came out $599.99. Not sure if it will last that long though. <3 Emotion Chip

He isn't whining, nobody wants extra systems, controllers.... who wants to deal with memory cards and wired controllers? The Wii offers BC. The 360 offers BC. Sony should as well. I am disappointed with the lack of BC given the ps2 had a glorious lineup.

"On the other hand, the Xbox 360 uses about 187 watts while playing a game, which makes the PS3 Slim"
Ding! Ding! Ding! Fanboy alert. Why are you comparing the just released Slim with the original, launch Xbox 360? Did you think people wouldn't notice that little detail? Compare it to the Jasper units which have been on sale for the last year. BTW, you forgot to mention the new Slim's Blu-ray pickup is about 10%-20% slower. Also, the newer (cheaper) ones Sony has been using tend to fail after a year (just out of warranty) and the repair cost is $150. Google YLOD or Yellow Light Of Death. Interesting that while the newer 360s have been getting more reliable and more features (and cheaper), the newer PS3 are getting more unreliable and removing features.

Ding Ding Ding fanboys alert. You set off your own damn fanboy alarm with your fanboyism. The man is just stating the truth. He also did mention the wii not just the xbox360. If he wouldve just mention the xbox360 then yes its a little fishy but he didnt. Go rant your nonsense somewhere else, loser.

@DLPTheSmartChoice Fanboy...who's the fanboy.. you sound like the typical sour xbox owner... all he did was point out the power consumption. And you get all angry and make crap up. PS3 owners had to put up with this site and fanboy users like you bash us constantly for 2 years. The media bias was outrageous against the PS3. And one site says one thing against the rrod machine and you get mad about it....hmmm... It's a fact that rrod was known by MS, why stick with a brand that intentionally ripped off it's userbase, made previous xbox 1 owners buy a new system when the last was only out for 4 years and they dropped all support..meanwhile Sony is still supporting the ps2 almost 10 years later and its still making green. The PS3 has always been the best bang for your buck, fanboys just had a high price to bash on, now is not the case and you fanboy are grasping for straws....

Fact the PS3 Slim uses half the power of the PS3 og model, fact it uses half the power of 360, fact less heat == better reliabilty! Fact 360 is still getting rrod and e-74, Fact Game informer did a poll on 5000 console owners and 54% have had to send their console back to MS.... Fact...Ps3 offers more features, built in wifi, blueray, blue-tooth, laptop hard drives, more movies, internet browser, free online play, half the power, and cures cancer....for the same price as the 360 that doesn't have wifi, has proprietary hard drives at 10x the cost, a rip off Toll Tax to play your games online and still made to see ads, no internet., twice the power consumption, unreliable, RROD, Don't get it twisted... its a fact .. the PS3 slim is a better deal and has more newer real Exclusives.

The title of the article as it appears on the CNET homepage is misleading. 'PS3 Slim: Half the power of PS3 "fat"' sounds like the hardware is inferior, or runs slower, or what have you. People who just glance at those headlines are going to get the wrong idea.

damn the 360 us 187 watts of power? is that per hour or what?

"Power" is an instantaneous rate of energy usage. A watt is equivalent to one joule (energy) per second (time). Put another way, a joule is a watt-second. Run your 360 at 187 watts for an hour, you've used up 187 watt-hours, or 0.187 kilowatt-hours. Run it constantly for a thirty-day month, and the energy consumption is 5.61 kWh.

Ok, we need to restate that sentence about playing time, and cost savings! Let's try it this way....

"If you generally play for about 5 to 10 hours a week, you'll save less then $10.00 per year using a PS3 Slim vs. an older model. If you're hardcore enough to rack up 20 hours of gaming per week, you'd still only save about $50 over a three-year period....

[Now for the new stuff]

... If you have absolutely, positively ZERO life, and spend 50 hours a week playing video games as a couch potato only to find that the hot girl you met online is actually a dude, you'd still only save about $100 over a three-year period.

Seriously people, I like video games and all, but 50 hours a week!? I don't think I've done that in any week, no less consistently.
