Kuroutoshikou Galakuro Gaming GeForce RTX 5080 Triple Fan OC

Manufacturer: Kuroutoshikou

The Kuroutoshikou Galakuro Gaming GeForce RTX 5080 Triple Fan OC is a desktop graphics card based on NVIDIA's Blackwell architecture, manufactured on a 5 nm process with 45,600 million transistors. It features a triple-fan cooling setup and comes with RGB lighting, fitting into a card measuring 303 mm in length and 125 mm in height. With a 3-year warranty and support for up to four simultaneous displays, it covers a broad range of use cases from gaming to content creation.

On the technical side, the card runs at a base clock of 2295 MHz with a turbo frequency of 2625 MHz, delivering 56.45 TFLOPS of floating-point performance alongside a texture rate of 882 GTexels/s. Its 16GB of GDDR7 memory operates over a 256-bit bus at an effective speed of 30,000 MHz, yielding up to 960 GB/s of memory bandwidth. The card supports DirectX 12 Ultimate, OpenGL 4.6, OpenCL 3, ray tracing, DLSS, and Intel Resizable BAR, and connects via one HDMI 2.1b port and three DisplayPort outputs. With a TDP of 360W and a PCIe 5 interface, it requires a suitably capable platform and power delivery setup.

Pros
  • Supports up to four simultaneous displays, making it suitable for multi-monitor setups
  • Includes ray tracing and DLSS support, enabling more advanced rendering capabilities in compatible titles
  • 16GB of GDDR7 VRAM with 960 GB/s of memory bandwidth provides substantial headroom for memory-intensive workloads
  • ECC memory support adds a layer of data integrity for error-sensitive tasks
  • Comes with a 3-year warranty, offering extended post-purchase coverage
  • Intel Resizable BAR support allows the CPU to access the full GPU frame buffer, which can improve data transfer efficiency
Cons
  • 360W TDP places significant demands on system power delivery and cooling infrastructure
  • No USB-C display output, which limits compatibility with certain modern monitors and devices
  • Does not support water cooling, leaving users reliant solely on the triple-fan air cooling solution
  • XeSS (XMX) is not supported, reducing upscaling options to DLSS only
  • At 303 mm in length, the card may not fit in smaller or compact PC cases
Who is this for?

This card is well-suited to users running demanding rendering and compute workloads, where the combination of 56.45 TFLOPS of floating-point performance, 16GB of GDDR7 VRAM, and ECC memory support can handle large datasets and complex scenes with greater reliability. Content creators and technical users who work with memory-intensive applications will benefit from the 960 GB/s bandwidth and the broad API support across DirectX 12 Ultimate, OpenGL 4.6, and OpenCL 3. It also fits well in multi-display workstation setups, given its four-output configuration and Intel Resizable BAR support, making it a practical choice for users who need both screen real estate and computational throughput.

Who is this NOT for?

Users working within space-constrained or compact builds may find the 303 mm card length a limiting factor, as it simply will not fit in many smaller form-factor cases. The 360W TDP also makes this card unsuitable for systems with modest power supplies or those not designed for high-wattage components, since running it in an underpowered setup risks instability. Additionally, users who rely on USB-C display connectivity or require water-cooling integration will find this card lacking, as neither feature is available here, which may be a drawback in specialized setups or premium cooling configurations.
