Power Requirements and Specs For Popular Graphic Cards Guide

[saaiello]

This is a reference to help guide you in the right direction for a power supply based on you graphics card.

Tom's did a really good review sometime back on Graphic's cards and Total System power consumption its a little old but still a good read.
Tom's Hardware Power Usage Review

Power Supplies
Guide to buying PSUs
A list of PSUs (a bit out of date but most recommendations still apply)

■Suggested Brands
Corsair, Antec, SilverStone, Seasonic, and OCZ. Read the reveiws for the OCZ's some arent as good as others so be careful when choosing a power supply.

■350 watt This will be enough for any processor and an entry level GPU

■400 watt This will be enough for any processor with a low to mid range GPU

■500 watt This will be enough for any processor and just about any mid range GPU

■550 to 650 watt This will be more then enough to run just about any single GPU, except for the HD 5970,HD 4870 x2, GTX 480, and GTX 295.

For Dual GPU setups add another 75 to 100 watts for low to mid range GPUS for the upper midrange to the high end add a 150 watts on average per GPU. See my list for more info on some popular GPUs and what I suggest for them.

To figure out how many amps you need on the 12 volt rail use this formula (watts / 12 = amps) so if the card requires 650 watts simply divide 650 by 12. This formula only works for 12 volt for different voltages there are different dividers.
■650/12=54.16 so if it requires 650 watt PSU it will need 54 amps on the 12 volt rail, for PSU with multiple 12 volt rails you will need to find the max combined output for it. Now this number may be a bit higher then it actually needs but it will give you a rough estimate since AMD and Nvidia dont give the amperage requirements for all their cards.

Can't you just go to
http://www.gpureview.com/
And get specs and power requirements?

You very well could but that does not bring hits to tomshardware.

I will be sitting down with this tomorrow and update with all the new cards that are out.

 

[saaiello]

This is a very helpful thread.

So at the moment I have a seasonic x750 to go with my i7 2600k and 6950. However I just found a deal for a couple of gtx 570s.

If I run the 2600k oc to around 4.2Ghz plus the 570s SLI oc to 800, will my 750w be good? what would you recommend?

Your Seasonic will have no problems running a couple 570's and the I7 with its OC. The unit will be getting close to its max rated but the x750 should it just fine. You should even have some headroom for a liquid cooling setup if that is in the future for your rig.

 

[gc_sama]

Thanks for the quick reply. I have a follow up question too.

Since the power supply will be nearing its max with my setup, do you think an x850( or whatever 80 plus gold you recommend) would be better for this setup plus a SSD?:

[saaiello]

If you already have the SeaSonic x750 I see no reason at all to upgrade to the 850. The x750 is plenty of power supply for your rig.

 

[MasterZoen]

SAAIELLO, I have to say, this is one of the best threads on the web. I'm building a new enthusiast rig based on the 6970 and I hope you'll have the amps up soon.
Thanks for all the great work you put into this thread!

Hello folks,


Here's one question for power supply requirements concerning my Z800 system with:


Liquid cooling option

2x X5680 CPU

6x 4GB ECC RAM

4x 7200rpm SATA disk

2x SATA SSD

1x DVD-Burner

1x BluRay burner

1x AMD HD6950 2GB


I went for the 1110W supply, which should translate to a 1250W (according to site prep guide) on the 220V power grid I'm running it on.


However, the site preparation guide classifies my intended setup (2x 130W CPUs with a second 6950 (so 2x 200+W graphics cards) as a "High Risk" combination and the maintenance and service guide states "Requires memory and CPU configuration restrictions" for 2x225W cards. Neither of them elaborates on the exact nature of those restrictions and how to determine the limits.


1. What exactly is the risk I'm running i.e. what is the worst which could (realistically) happen?

If it's "just" the power supply burning out, that I could (somehow) live with (even though spending another few hundred for a replacement doesn't really get me all excited). What I absolutely can't have is large parts of/the whole rig dying on me; I need it for work, it's a considerable investment for me and I has to last for 4+yrs (just like the XW9300 it replaced)


2. So, do you think the PSU can take the second 6950? Which 12V-rails should I have the graphics cards draw power from? The 1110W has 2 separate PCIe 6-pin (both in the single 6950), but I'd obviously need 2 for each of the 6950. Should I split the VG rails or give each card one of them and add another split from the drive rail?


3. On the whole, I don't really know how to properly determine the power requirements of the system as a whole. Taking the specs of the components and adding a safety buffer, I top out at 950W somewhere with my guesstimates.

I also did a pessimistic (reading: assume more components, taking more power than specified) with one of the psu calculators online I get the following: With 1110W (@1250W for 220V, if that is even true) is that 1080W too close?

(NOTE: i'm not really overclocking, I don't have 12 sticks of ram, only 6, the pcie slots really are empty except for the 6950,etc.etc., but as I said: safety first)


Many thanks

Where's the GTX 560 Ti?? Would love some info on power requirements for this one as it is sitting in my Newegg shopping cart atm.

 

[fermata]

Good thread. One thing I noticed is that you have the 5870's core clock at 870mhz when its actually 850mhz

Mee too,I have the same one at 870mhz

 

[saaiello]

The 560 TI will run fine on a good quality 500 watt power supply. It is a relatively low powered card an has almost identical requirements and power specs as the GTX 460 in fact Nvidia claims it uses 10 watts less at full load but recommends 50 watts more for the power supply figure that out lol.

Liquid cooling option

2x X5680 CPU

6x 4GB ECC RAM

OK I looked this over 4 times very confusing your post was , but I checked it over 3 times for your system with dual 6950's you are looking at around 900 Watts MAX. A more realistic number is more like 850 watts.

2x X5680's 130 watts each
High End Dual CPU motherboard & RAM 100 watts
DVD & BluRay 10-15 watts each
4x hard drives 10-15 watts each
2x SSD's 5 watts each
2x 6950's 150 watts each

760 watts

Now I am gonna be generous and add about another 100 watts for a few extra PCI cards and some firewire and USB devices so 860 watts is a realistic number.

The 1110 watt power supply should be enough, but I have no clue how good of a unit comes with those systems. It would be interesting if you could find out how many amps are on each rail if you can.

Also to determine power for liquid options I would have to know the setup you plan on using but add another 50 to 100 watts depending on the setup.

 

[saaiello]

2 cards missing there.

6990 and the GTX 590

Hello,

I apologize for confusing you and therefore thank you all the more for taking the time to reply:

The components are all original HP parts (except for the 6950 and the BluRay), so the liquid cooling solution is the one specified here

from Asetek
http://www.asetek.com/products/oem-custom-products/hp-z800-workstations.html

Is the 6950 rated at 150W? I though the max power draw is 200W for that card.


Answers to the items you mentioned:

1. According to specification the PSU has the following rails

+12 V-CPU0 Input to onboard regulator that supplies power to CPU0 and CPU0 fan
+12 V-CPU1 Input to onboard regulator that supplies power to CPU1 and CPU1 fan
+12 V-M0 Input to onboard regulator that supplies power to memory on CPU0
+12 V-M1 Input to onboard regulator that supplies power to memory on CPU1
+12 V-B Input to onboard regulators that supply 3.3V and 5V, system fans
+12 V-S PCI, PCIe, and system fans
+12 V-D Storage (hard drive, optical disk drive, diskette drive), and input to
miscellaneous onboard regulators
+12 V-G1 PCIe auxillary connector for both connectors on 850W and one for 1110W
+12 V-G2 Second PCIe auxiliary connector on 1110W power supply
V12N PCI and serial ports
+5 V-SB Sleep circuitry

On the 1110W/1250W PSU each of the 12V rails can supply 18A, with a total maximum output of 92/104A.

quote from service and maint guide:
"Do not exceed 92.5A amps (1110 watts) of 12-volt (CPU0/CPU1/M0/M1/B/D/S/G1/G2) power
combination for the 1110W power supply."
"Do not exceed 104.2A amps (1250 watts) of 12-volt (CPU0/CPU1/M0/M1/B/D/S/G1/G2) power
combination for the 1250W power supply."

2. I cannot say much on the quality of the HP PSU, but here are the specs

1110W Wide Ranging, Active PFC*

The 6970 only has a max draw of 157 Watts under full load and in reality you would never hit those kind of numbers ever the 6950 which is the same card just a tad scaled down has a max draw of about 150 watts. Now overclocking of these cards will drive up their consumption a tad, but 200 watts is not gonna be pulled from these cards.

From the numbers you posted for the power supply it looks like a very capable unit you should be fine with your setup. The liquid coolers that the HP comes with is not a true liquid setup and does not use up any extra power to use it besides the power for the fans which is a few watts per fan.

So in conclusion it looks like you will have a killer setup and will have plenty of power for just about anything.

That 500 watt unit you have is not enough it only has 22 amps on the 12 volt way to weak for alot of graphics cards. Wait for the TP 750 before you run even one 560 TI.

that psu can produce 35A on the 12V so it can pull a 560 with ease. The 500 series got a current limiter chip as well so if the psu runs low on juice it slows the card down to use less power.

Hello,

I'm rather new in PC self-customization and am looking for guidance.

I must say, I think I may have made a little boo-boo with my PSU choice and seem to be getting a little uneasy on how things are going.

Now, before I go about changing my PSU (due to a problem I'm experiencing here: http://www.tomshardware.com/forum/304232-28-surge-help), I just want to ask on whether this current PSU is ideal for the graphic card in use in my desktop.

PSU used is Silverstone SE ST60F-ES (600W), graphic card used is Radeon HD6850.

Yes that power supply is fine for your setup. I read thru your thread and as others said your problem is poor regulation inside the power supply itself. Without testing the unit with a digital multi-meter its hard to tell for sure if its the power supply or the motherboard reading the voltages wrong. It is very bad for your hardware if the PSU is indeed over volting your system. I suggest changing it ASAP and stop trying to boot it, you could cause damage to the rest of your hardware if you do.
