The guys over at EKWaterbloks, in their usual short and to the point fashion, have issued the following cautionary statment.

- 21/02/2012

Caution! All currently available Radeon HD 7770 (PCB# 109-C44157-00) series graphics cards are NOT compatible with EK-VGA Supreme HF series water block via Mounting Plate VGA Supreme HF HD6770.

 

Reason for this is the VRM (voltage regulation module) which is located too near the GPU itself. EK Water Blocks has no plans in making the water block for Radeon HD 7770 at the moment.

 

On the other hand it seems all reference design Radeon HD 7750 graphics cards (PCB# 109-C44557-00) are compatible with EK-VGA Supreme HF series water block via Mounting Plate VGA Supreme HF HD6770. There seems to be no components obstructing installation.
