Announced back in April, Galax's GTX 1070 Katana caught our attention for counting itself among the few single-slot gaming graphics cards available today.
In fact, to the best of our knowledge, this is the only single-slot, air-cooled GTX 1070 in the world, as anything with a thermal design power of 75 watts or higher is typically paired with a dual-slot cooler for the added heat dissipation.
There's no doubt that this is a niche product, but it should call to compact system builders who would rather not sacrifice an additional expansion slot, which could otherwise be used for hardware such as a dedicated sound card, an NVMe SSD, a Thunderbolt 3 controller, or extra SATA ports.
This card may also become a popular choice for those building workstations with multiple high-end graphics cards because you only need a single slot between the cards for SLI support rather than the typical two slot spacing, which is to say that pair of Katana cards should deliver better operating temperatures than bigger dual-slot cards on boards such as the Asus ROG Strix Z270G Gaming or Asrock Z270M Extreme 4, for example.
Covering the entire front side is a pancake-like aluminium fan shroud which has been painted gunmetal grey.
What we found was a 4+1 VRM which is the same configuration used by Nvidia's Founders Edition model, though the VRM has switched sides and is now placed behind the display outputs.
