KFA2 GeForce RTX 5090 1-Click OC

Manufacturer: KFA2

The KFA2 GeForce RTX 5090 1-Click OC is a high-end graphics card from KFA2, built around NVIDIA's Blackwell architecture. It ships with a factory-overclocked configuration, running a base GPU clock of 2017 MHz and a boost clock of 2407 MHz. The card carries a 32GB GDDR7 frame buffer across a wide 512-bit memory bus, pairing substantial on-board memory with the bandwidth demands of modern rendering workloads. RGB lighting is integrated into the card's design, and it measures 326 mm in length and 137 mm in height.

On the technical side, the RTX 5090 1-Click OC delivers 104.8 TFLOPS of floating-point performance alongside a texture rate of 1637 GTexels/s and a pixel rate of 423.6 GPixel/s. Its 21,760 shading units are complemented by 680 texture mapping units and 176 render output units. Memory bandwidth reaches 1792 GB/s at an effective speed of 28,000 MHz, supported by ECC memory compatibility. The card draws power at a rated TDP of 575W via PCIe 5.0 and is fabricated on a 5 nm process containing approximately 92,200 million transistors. It supports DirectX 12 Ultimate, OpenGL 4.6, OpenCL 3, ray tracing, and DLSS, and can drive up to four displays simultaneously through one HDMI 2.1b port and three DisplayPort outputs.

Pros
  • The 512-bit memory bus paired with 32GB of GDDR7 VRAM provides substantial frame buffer capacity for texture-heavy and high-resolution workloads
  • A maximum memory bandwidth of 1792 GB/s ensures rapid data throughput, reducing memory bottlenecks during complex rendering tasks
  • Support for ray tracing, DLSS, and DirectX 12 Ultimate enables compatibility with a wide range of modern rendering techniques
  • ECC memory support adds a layer of data integrity, making the card suitable for workloads where memory accuracy matters
  • Intel Resizable BAR support allows the CPU broader access to GPU memory, which can improve data transfer efficiency
  • RGB lighting is integrated into the card's design for users who want visual customization in their build
Cons
  • A 575W TDP places significant demands on power supply capacity, requiring a high-wattage PSU and adequate system cooling
  • The card measures 326 mm in width and 137 mm in height, which may not fit in smaller or compact cases
  • Air-water cooling is not included, meaning users must rely entirely on the card's default air-cooling solution
  • Only one HDMI port is available, with no USB-C or DVI outputs, limiting connectivity options for certain display setups
  • XeSS (XMX) is not supported, restricting upscaling options to DLSS only
Who is this for?

This card is well-suited to users who regularly work with demanding rendering, compute, or high-resolution gaming workloads, where the combination of 32GB GDDR7 VRAM and 1792 GB/s memory bandwidth can be meaningfully utilized. The inclusion of ECC memory support also makes it a practical choice for professional and compute-oriented environments where data integrity is important. Users who want access to ray tracing, DLSS, and DirectX 12 Ultimate across up to four simultaneous displays will find the feature set well-aligned with those needs, particularly in spacious full-tower builds that can accommodate a 326 mm card and manage the 575W power draw.

Who is this NOT for?

Users working within compact or small-form-factor builds are likely to find this card impractical, given its 326 mm length and 137 mm height, which may not fit within tighter chassis constraints. The 575W TDP also makes it unsuitable for systems with limited power supply headroom, as meeting that requirement demands a high-wattage PSU and sufficient airflow. Additionally, users who depend on USB-C display output or DVI connectivity will find no support for those interfaces here, and those seeking XeSS-based upscaling will need to look elsewhere, as only DLSS is available.
