It's worth noting that even with our 90° barbs, the Poseidon is still fairly wide when watercooled and thus you should make sure that you're not looking to fit it into a narrow chassis.


As always with some extra cooling it would be easy to imagine that there is a swathe of extra performance on tap, but as we know well the silicon lottery ensures that, barring some major cherry picking, you'll more than likely end up with a chip that performs much the same as any other.

So it is in some regard unsurprising that the Poseidon hits nearly 200MHz more than it comes out of the box. We'd expect nothing less from a ROG branded card. The primary function of the cooler though is to cool, as we'll see in our temperature graph.

With air-cooling the Poseidon is right on point, with a maximum of 73°C under loading. Given that some compromise has to be made for the water-cooling element, this is very good indeed. Under water it is vastly superior, as we'd expect. It's a fantastic way of demonstrating the difference between air and water. 30°C is nothing to sniff at.

Tom, one small suggestion, usually I'm not a grammar Nazi as long as I understand what anyone is trying to say but the way you pronounce "Poseidon" made me cringe when I was watching the Rushkit video Quote

I really like this card, it looks absolutely awesome. In my opinion though Asus need to drop the price by £30-40 to further distance that gap between full cover and this hybrid cooler.

Personally, if I was going all out to watercool my rig and considering the costs of the Poseidon is the same as a 780 with a full cover block, I would go for the full cover over this.
But, if the price of the Poseidon was that £30-40 cheaper then I (and many others) would be more than likely to go for it.

For the convenience and warranty issues and all the rest of it, it is worth it though.Quote

I really do like this card, very good design. A well deserved innovation award.

It was a shame ASUS were unable to change it to a 780Ti variant, but that's more nvidia's fault than anyone else, releasing a new gaming flagship without any notice.

I do hope we will see more cards of this design in the future.Quote
