Kuroutoshikou GeForce RTX 5080 Triple Fan OC

Manufacturer: Kuroutoshikou

The Kuroutoshikou GeForce RTX 5080 Triple Fan OC is a high-specification graphics card from Kuroutoshikou, based on NVIDIA's Blackwell architecture and manufactured on a 5nm process node. It ships with a factory overclock that raises the boost clock to 2760 MHz, up from a base of 2295 MHz, and includes RGB lighting along with a triple-fan cooling configuration housed in a 341mm x 145mm form factor.

On the memory side, the card carries 16GB of GDDR7 VRAM across a 256-bit bus, delivering a maximum bandwidth of 960 GB/s at an effective speed of 30000 MHz. Compute capabilities reach 59.35 TFLOPS of floating-point performance, supported by 10752 shading units, 336 TMUs, and 112 ROPs. The card supports DirectX 12 Ultimate, OpenGL 4.6, ray tracing, DLSS, and Intel Resizable BAR, with display output handled through one HDMI 2.1b port and three DisplayPort connections for a total of up to four simultaneous displays. Its TDP is rated at 360W, and it connects via a PCIe 5.0 interface.

Pros
  • Supports up to four simultaneous displays through a combination of one HDMI 2.1b port and three DisplayPort outputs
  • ECC memory support adds a layer of data integrity for workloads that require reliable computation
  • The 256-bit memory bus paired with 16GB of GDDR7 VRAM delivers a maximum bandwidth of 960 GB/s
  • Ray tracing and DLSS are both supported, expanding compatibility with modern rendering techniques
  • Intel Resizable BAR support allows the CPU to access the full VRAM pool, which can improve frame delivery in compatible systems
  • RGB lighting is included for users who want visual customization in their build
Cons
  • At 360W TDP, the card places a substantial power demand on the system and requires adequate PSU headroom
  • The card does not include water cooling support, relying solely on its air-cooling solution
  • No USB-C output is available, limiting direct connectivity with certain modern monitors and displays
  • The one-year warranty period is relatively short for a product in this category
  • At 341mm in length, physical fitment may be a challenge in smaller or mid-tower cases
Who is this for?

This card is well-suited to users running demanding rendering and compute workloads, given its 59.35 TFLOPS of floating-point performance, DPFP support, and ECC memory — making it a practical choice for those working with 3D rendering, simulation, or precision-sensitive tasks. Gamers and content creators who want to take advantage of ray tracing and DLSS in modern applications will find the architecture fully capable of supporting those pipelines. The four-display output configuration also makes it a strong fit for users who require a wide multi-monitor setup, whether for productivity, creative work, or immersive gaming environments.

Who is this NOT for?

Users working within a power-constrained system may find this card difficult to accommodate, as its 360W TDP demands a robust power supply and adequate airflow — making it a poor match for compact or low-wattage builds. Those looking to install the card in a smaller chassis should also take note of its 341mm length, which can create fitment issues in mid-tower or mini-ITX cases. Additionally, users who require USB-C display output or water-cooling compatibility will find neither option available here, which may limit its appeal for certain specialized or space-efficient setups.

Final Verdict

The Kuroutoshikou GeForce RTX 5080 Triple Fan OC is a well-specified graphics card that brings together the Blackwell architecture, 16GB of GDDR7 memory, and a 960 GB/s memory bandwidth into a package built for users with serious rendering, compute, or multi-display demands. Its support for ray tracing, DLSS, ECC memory, and DPFP gives it genuine versatility across both creative and precision workloads, while the four-output display configuration adds practical flexibility. That said, its 360W power draw and 341mm length mean it requires a well-equipped system to operate at its full potential. For users whose setup can accommodate those requirements, this card represents a technically complete solution for high-demand workloads.
