EK GTX 780 Classy block on a GTX 770?

post #1 of 6
Thread Starter 
Hey guys,

Been searching around for a water cooling solution for my SLI GTX 770 Classifieds with extended PCB, turns out do not buy these cards if you want to put them on water.

I found EK released a block for the GTX 780 Classified with extended PCB and am wondering if this would fit the my cards? I have been looking at the PCB and it looks like all but one screw is in the same place, and the vrams etc are all located in the same spots as well. Can anyone give guidance?

The 780 classy block will not fit. The swiftech block is the only one that was "made" for that card. I've heard that the older 680 classified block will also work, but its the same situation of it only being made by swiftech.

Should I just go with a universal block at this point then?

Cooling Configurator is your friend :)

 

Here are the cards that the 780 Classy block is compatible with:

I'm assuming one of these are your cards:

So unfortunately that's a no.

 

Does your 770 Classy come with a "reinforcement baseplate" like the 780 Classys do?

That'll make sticking a uni GPU block on there super simple.

 

You could always do something like this as well (780 Ti KPE)

Here is my card: http://www.evga.com/Products/Product.aspx?pn=04G-P4-3778-KR

Their site says I have the baseplate. How does that make sticking a universal block on my card easier? Does that mean I don't need to cool the vram etc?
post #6 of 6

Yeah. I mean you could get away with the baseplate cooling the memory vrms if you wanted, but if you really want to push your 770 classy you'll probably still want to put some small passive sinks on the board. Overall though it keeps the uni gpu block "system" a lot cleaner looking imo compared to cards without the baseplate. As always you should be sure to have at least SOME air flowing over the card.
