VGA Power Consumption

Life is not as affordable as it used to be, and items such as gasoline, natural gas, and electricity all top the list of resources which have exploded in price over the past few years. Add to this the limit of non-renewable resources compared to current demands, and you can see that the prices are only going to get worse. Planet Earth is needs our help, and needs it badly. With forests becoming barren of vegetation and snow capped poles quickly turning brown, the technology industry has a new attitude towards suddenly becoming "green". I'll spare you the powerful marketing hype that I get from various manufacturers every day, and get right to the point: your computer hasn't been doing much to help save energy... at least up until now.

To measure isolated video card power consumption, Benchmark Reviews uses the Kill-A-Watt EZ (model P4460) power meter made by P3 International. A baseline test is taken without a video card installed inside our computer system, which is allowed to boot into Windows and rest idle at the login screen before power consumption is recorded. Once the baseline reading has been taken, the graphics card is installed and the system is again booted into Windows and left idle at the login screen. Our final loaded power consumption reading is taken with the video card running a stress test using FurMark. Below is a chart with the isolated video card power consumption (not system total) displayed in Watts for each specified test product:

* Results are accurate to within +/- 5W.

The ASUS EAH5870 V2 pulled 28 (158-130) watts at idle and 265 (395-130) watts when running full out, using the test method outlined above. The idle power consumption test is right on the factory number of 27W, and the load value is 77W above the 188W factory spec. That's about normal for this test, as it isn't possible to isolate the CPU load from the power measurements. You also have to factor in the efficiency of the power supply, which changes at different load levels. I think it's fair to say that the card pulls every bit of the full load current that is specified by the manufacturer, and maybe a few watts beyond that.

So, no major surprises in the power consumption area; it's ATI's biggest GPU, running at high clock rates. A good thing it's built on 40nm technology, otherwise those two billion transistors would be pulling a lot more power and generating a lot more heat. I next offer you some final thoughts, and my conclusions. On to the next page...

# Excellent reviewAdos 2010-06-16 09:05
Excellent review, one of the best I have ever red on a graphics card. Perfectly examined power section, built quality, overclockability. Do you think will I be able to run this card overclocked in my system? I think it would be ok, but maybe wee bit close to maximum for my powersuply. I run QX9650 at 3.5 GHZ (10.5 x 333 on Gigabyte mATX G31 ESL2 board, 2x2GB DDR2 corsair DHX, and the most important - PSU Enermax MODU82+ II 525W with 3x12V 25 amps on each but 40 amps maximum combined. Thank you for your opinion. And once more what a GREAT REVIEW!!!

# Thanks.Bruce Normann 2010-06-16 11:32
Thanks for the positives...it's always appreciated. Your Enermax is an excellent PSU, and it should do the job. My only concern is if you are doing Folding or Benchmarks all the time. Even then, the total PSU load will probably stay under 400W.

BTW, I was reading that one of the 12V rails is dedicated to a single PCI-E connector, while the other two are sharing the current between PCI-e and the MOLEX and SATA connectors, so verify that and use the dedicated connection if you can.

# Also....Bruce Normann 2010-06-16 14:12
The ASUS EAH5870 V2 comes with an adapter cable to convert two 6-pin PCI-e cable to one 8-pin connector. If you use this adapter, you will be spreading the load on all three rails.

# Thank you!Ados 2010-06-16 18:03
Thank you very much for quick reply and advice. Much appreciate it. Just to clarify things, here is a picture of 12V rails layout - ##anandtech.com/show/2487/6 - so considering that I have two graphics sockets connectors on the PSU and two cables to connect them to of which one of the cable has only one 6+2 pin connector and the other cable has 2x 6+2 pin connectors I should plug the 6+2 pin connector to outer one dedicated graphics power socket on the PSU and the second cable with 2x 6+2 pin connectors to the inner graphics power socket and then spread that output by using and included adapter to convert those 2x 6+2 pin cable to 1x8 pin cable to spread the load properly, right? But I wont be probably spreading the output on all three rails anyway because one 12V rail according to the pictures in the link is probably dedicated to CPU only. Am I correct? Thank you for your seamless advice and help.

# Or the otherwayAdos 2010-06-16 18:31
When I looked at that picture with power distribution on 12V rails again ( ##anandtech.com/show/2487/6 ) I think all what is needed is actually connect that 2x 6+2 pin cable to inner graphics power sockets on the PSU because I think its obvious that that one combines both 12V2 and 12V3 rails and then just plug that 2x 6+2 pin cable to the graphics card. What do you think?

# Looked CloserBruce Normann 2010-06-16 20:36
Your right, each red connector on the PSU has both rails contained in it. 12V2 is dedicated to the grphics cards only. It's the one with the yellow sleeve on the internal wiring, and when you plug the connector in, on the outside of the unit, it will be the set of wires closest to the edge. I would use that for the 8-pin connection, and the other set (12V3) for the 6-pin.

# re: Looked CloserAdos 2010-06-16 22:49
I think only the inner red connector has both 12V2 and 12V3 rails and to that one I will plug that cable which splits into two 6+2 pin PIC-e cables. Enermax did a good job marking the wires on that cable so its obvious which one of two 6+2 pin connectors will use the 12V2 and which 12V3 and as you said I will use the 6+2 pin on 12V2 to power the 8pin on the card and the another 6+2 pin will use 12V3 and I will plug it to 6pin on the card. BTW: I am going to use this card in this mATX case - ##tomshardware.com/reviews/4-barebone-cases-compared,1901-5.html - its so smartly designed that it can take even such a long card even with connector placed where they are on that card. Sorry for any confusions and thank you very much for your time and effort as well as for prompt replies and advices. Thanks to the discussion with you I understand it now and have the correct idea how to plug that card into my PSU in the best way possible. Wish you all the best in whatever you do! :-]

# RE: ASUS Radeon EAH5870 V2 Video CardxGreg 2010-06-16 18:59
Bruce Excellent review.

I just bought this card (After reading your review), but now I'm VERY worried about if my power supply (Corsair VX550W) can handle this card...

My System:

Q9650 Stock
Gigabyte GA-EP45-UD3P
2x2GB DDR2 1066MHZ OCZ Reaper Series
Western Digital Caviar Black 1TB
Western Digital Caviar Green 500GB
Western Digital Caviar Green 2TB
Zalman 9700NT
Antec 900 (4 Fans 120mm, 1 Fan 200mm)

Thank you for your consideration of this matter.

# I wouldn't worryBruce Normann 2010-06-16 20:40
I actually own one of these, and it is rock solid. Even theough it is not modular, it has the exact cables you need for this graphics card, one 6-pin and one 6+2 pin. Check out the review on jonnyguru.

# RE: I wouldn't worryxGreg 2010-06-17 23:52
Thank you for you answer.

You said maximum power draw of this card is 265 (395-130) watts when running full out. What do you mean with 395 watts? Total System Power Consumption?

Maybe the power supply will work too forced? Or Maybe will work too forced if I overclock my CPU and Graphic Card?

Perhaps it will reduce the life of the power supply? I've been told when used heavily or over an extended period of time (1+ years) a power supply will slowly lose some of its initial wattage capacity.

My PSU is two years old, and I use it 24/7.

Thank you for your consideration of this matter.

# Total System PowerBruce Normann 2010-06-18 06:46
The entire system used a total 395 watts of power from the wall receptacle while running FurMark. This is an extreme load for the video card, and you would not see that kind of sustained load while gaming.

What are you running on the PC during the 24/7? Is it just idling most of the time, or are you running applications that put a significant load on the PC?

At 80% load, your PSU will probably only last 10 years.....just a guess.

# RE: Total System PowerxGreg 2010-06-18 16:37
Hello again Bruce, and thank you for your answer. I really appreciate it.

And Yes, Is it just idling most of the time. However, I play games almost every night and weekends. Very Demanding games like Bad Company 2 for example.

I have another question about your review. Does the CPU is also in full load? Or is it just the graphics card?

I've been thinking, and I think my supply might not be sufficient in the near future, when I change my current processor for an i7 or add a sound card, etc.. Am I right?

I dont know whether to buy a new psu or stay with the one I have.

What would you do if you were in my situation??

# Your Upgrade PathBruce Normann 2010-06-19 22:01
Well, if I was on an upgrade path like what you describe, I would probably start looking for a good deal on a Corsair HX 850. In the mean time, why don't you buy one of the KILL A WATT power meters, and try stressing your system with Furmark and OCCT? They are only about $25... Then you will KNOW what your VX550 is up against. OCCT will print graphs of all the major system voltages (12V, 5V, 3.3V...) and you will see for yourself if it is holding up at the highest possible loads for YOUR system, not someone else's.

You can recoup some of your costs by selling the VX550, as it has a very good reputation.

# RE: Your Upgrade PathxGreg 2010-06-20 19:17
Hello again Bruce.

I'n going to buy a new PSU, and will be a Corsair HX750 from Amazon. I think a Corsair HX850 is too much (Power and Price lol), unless I get $ 20 extra.

Thank you for everything ;)

# Alternative PSUBruce Normann 2010-06-16 20:55
BTW, for anyone who absolutely cannot power this, or any other powerful card (Fermi, Cough Cough!).... Thermaltake makes a neat PCI-e only (12V DC) power supply that fits in two 5.25" bays and provides 650 watts just to the graphics card(s): ****thermaltakeusa.com/Product.aspx?C=1265&ID=1544 It has modular connections, so cable management is good, too. Folks mainly use it for building dedicated folding machines, where they run quad-SLI.

Will this card supported 3 monitor???

EAH5870/2DIS/1GD5/V2

what does it meant of 2DIS-----> is that meant will just support 2 monitor???

If they are all DisplayPort models, you can connect three monitors. Otherwise, this video card will not support three DVI monitors.

The 5870 will show a tremendous increase in performance over the 4870... but if you read the reviews you would already know that.
