Maxsun GeForce RTX 5070 iCraft OC

Manufacturer: Maxsun

The Maxsun GeForce RTX 5070 iCraft OC is a desktop graphics card based on NVIDIA's Blackwell architecture, manufactured on a 5 nm process with 31,100 million transistors. It carries an overclocked boost clock of 2572 MHz and delivers 31.6 TFLOPS of floating-point performance, making it a capable option within the RTX 5070 product line. The card includes RGB lighting and supports up to four displays simultaneously.

On the memory side, the iCraft OC is equipped with 12GB of GDDR7 VRAM running across a 192-bit bus at an effective speed of 28,000 MHz, yielding a maximum bandwidth of 672 GB/s. It supports DirectX 12 Ultimate, OpenGL 4.6, OpenCL 3, ray tracing, and DLSS, along with Intel Resizable BAR. Display connectivity is handled through one HDMI 2.1b port and three DisplayPort outputs. The card has a rated TDP of 250W, measures 320 mm in length and 132 mm in height, and connects via PCIe 5.

Pros
  • Supports up to four simultaneous displays, offering flexibility for multi-monitor setups
  • GDDR7 memory running at 28,000 MHz effective speed delivers 672 GB/s of bandwidth across a 192-bit bus
  • Ray tracing and DLSS are both supported, enabling access to advanced rendering capabilities
  • ECC memory support adds a layer of data reliability for error-sensitive workloads
  • RGB lighting is included, allowing for visual customization within a build
  • Intel Resizable BAR support is included, enabling the CPU to access the full GPU frame buffer
Cons
  • No USB-C display output is available, limiting connectivity options for certain modern monitors
  • Air-water cooling is not supported, restricting cooling to the card's built-in air solution only
  • At 320 mm in length, the card requires a sufficiently spacious case to fit properly
  • The 250W TDP places notable demands on the system power supply
  • XeSS (XMX) is not supported, ruling out that upscaling option entirely
Who is this for?

This card is well-suited for users running demanding graphical workloads that benefit from ray tracing and DLSS, such as modern AAA gaming or real-time rendering tasks. The 12GB of GDDR7 VRAM paired with 672 GB/s of bandwidth makes it a solid fit for content creators and developers working with large textures or GPU-accelerated compute tasks, particularly those who require ECC memory support for data reliability. The four-display output capacity also makes it a practical choice for users building expansive multi-monitor setups.

Who is this NOT for?

Users working in environments that demand silent or highly thermally efficient solutions may find this card limiting, as it relies solely on its built-in air cooling with no air-water cooling option and carries a 250W TDP that places real demands on system power and airflow. Those with compact or small-form-factor cases may also struggle to accommodate the 320 mm card length. Additionally, users who rely on USB-C display connectivity or XeSS-based upscaling will find neither supported, which could be a meaningful limitation depending on monitor hardware or preferred upscaling workflows.
