The PNY GeForce RTX 5080 Slim OC delivers the full 10,752 CUDA core performance of NVIDIA’s Blackwell architecture in a strictly two-slot, 300mm-long footprint designed for space-constrained and small form factor builds. It combines a factory overclock with the latest GDDR7 memory to drive high resolutions in chassis that cannot accommodate standard oversized coolers.

True two-slot cooling for space-constrained builds

Modern high-end graphics cards frequently require three or four expansion slots, severely limiting case compatibility. This PNY model is engineered specifically to solve that problem. Measuring exactly 40mm in height, it adheres to a strict two-slot width, ensuring it will not block adjacent PCIe slots or suffocate against power supply shrouds in compact cases. At 300mm long and 150mm wide, it fits comfortably inside many popular Mini-ITX and Micro-ATX enclosures.

The thermal solution relies on a dual 120mm fan configuration, which moves a high volume of air over the heatsink to manage temperatures without requiring an extended card length.

Blackwell architecture with a 2730 MHz factory overclock

Under the cooler, the card is powered by the NVIDIA Blackwell architecture, featuring 10,752 CUDA cores to handle demanding rasterisation and ray tracing workloads. PNY has applied a factory overclock to this model, pushing the boost clock to 2730 MHz from the standard 2295 MHz base clock. This elevated frequency translates directly to higher frame rates in competitive titles and faster render times in creative applications. The card operates with a 360W Thermal Design Power (TDP), balancing high-end processing capabilities with a manageable thermal output for its size.

16GB of GDDR7 memory

Memory bandwidth is a critical factor for high-resolution gaming and complex 3D rendering. This RTX 5080 utilises 16GB of the latest GDDR7 memory, operating at 30 Gbps. Running across a 256-bit memory bus, this configuration delivers a total memory bandwidth of 960 GB/s. For the user, this means high-resolution textures load rapidly, and the GPU can maintain consistent frame pacing even when VRAM is heavily populated by modern titles or large video editing timelines.

PCIe 5.0 and DisplayPort 2.1b readiness

Connectivity on the PNY RTX 5080 Slim OC is built for high-refresh-rate displays. The card connects to the motherboard via a PCIe 5.0 x16 interface, ensuring maximum bandwidth between the GPU and the rest of the system. The rear I/O features three DisplayPort 2.1b outputs and one HDMI 2.1b port, supporting up to four monitors simultaneously. These advanced display standards allow the card to output ultra-high resolutions, supporting 8K at 165Hz with Display Stream Compression (DSC) or 4K at 480Hz for competitive gaming setups.

Power requirements and included adapter

To support the 360W TDP, PNY recommends pairing this graphics card with an 850W power supply. Power is delivered through a single 16-pin connector. For builders using older power supplies that lack a native 16-pin cable, the card includes a 16-pin to 3x 8-pin adapter in the box, ensuring compatibility with existing ATX 2.0 hardware. Note that this model does not support NVLink, operating entirely as a standalone GPU.
