7970 Quad-Fire

post #1 of 52
Thread Starter 
I am currently working on a new build that will have quad-fire 7970s in it. Anything I should know about any known issues with doing this?

Also, since I want to at some point liquid cool these puppies I want to know who should I go with for a maker and what version of the cards would I be happiest with? I have one XFX Double-D Black Edition 7970 but it is not the PCB ref design and will be hard for me to find a suitable water block for it.

Thank you guys in advance!

You will need Refrence Cards if you want to put waterblocks on them. The XFX Double D does not have a waterblock out there for it. Also you are going to need either a 1500 Watt PSU or you will need Dual PSU's.

Yeah I noticed that. Been digging and I found a card I am going to use, the HIS IceQ2 7970 seems to be a soild card and many people make full water blocks for it. As for the PSU thanks for the tip on that. I have not really be able to find any real data on what I should use.

How would I go about tieing two PSUs together?

I will be using the ASUS Rampage IV Extreme board for this project. How well do you think this will hold up?

Thanks buddy for your info!

Also upon more digging and running more calulations I am going to need at least 1700 watts to run this and that is with almost no head room. Looking into the legendary 2000 watt PSUs.....

I agree 1500W should be more than enough for your setup.

From this Guru3d review they calculated the power consumption of a 7970 to be 195W. So say 250W per card overclocked is only 1000watts. That leaves you 500W for everything else which is plenty.

And it has a 5th set of PCI-E cables so you can sue the EZ plug on the RIVE.

Just one issue with this, according the Enermax they only make the Platimax up to 1350W. The Enermax Maxrevo however goes up to 1500W. It's 80 Gold though.... not as good at Platinum.

Well there are only a couple percentage points difference between Gold and Platinum. The question is does it really matter to you if your PSU is 88% efficient instead of 90%? The 80 Plus rating shouldn't have an effect on how stable your voltage are though which is what matters most.

Having a higher efficient psu means you pull less power from the wall but with a 2-3% difference between gold and platinum your looking at like a 25-30 watt difference max of power pulled at the wall.

http://en.wikipedia.org/wiki/80_Plus

Like I said, the 80 plus rating shouldn't have too much to do with whether a psu is quality or not as far as the ripple and voltage output are concerned.
